Do-it-yourself filing of the roof cornice allows you to protect the roofing pie from external influences and give the roof an attractive appearance. Currently, there are many options for plating. We will focus on the most popular in this article.

Binder Features

Work on sheathing the roof overhang is recommended to be carried out after the installation of the truss structure, but before the arrangement of the crate for laying the roofing. Before filing the eaves, it is necessary to lay the waterproofing of the roof and it is desirable to perform roof insulation from the side of the attic. In addition, it should be noted that it is preferable to sew up the roof overhang before the start of external insulation of the walls of the house, so as not to damage the wall covering during work with the eaves.

At the first stage of work, the protruding parts of the rafters should be sawn off in one line, which should be parallel to the adjoining wall of the building.

The overhangs of the pitched roof are sewn up in such a way that gutters can be installed and ventilation of the roofing pie can be ensured. For these purposes, various materials and mounting technologies can be used.

Material selection

Traditionally, roof eaves sheathing is done using edged and planed boards. To make the roof look aesthetically pleasing, you should use boards that are the same in thickness and width. In addition to the board, various materials are widely used today, which should:

provide reliable protection of the eaves of the roof from moisture, frost, precipitation;
provide the necessary ventilation of the roof;
have resistance to external influences and durability;
have aesthetic appeal.

Popular materials for arranging a cornice overhang include:

lining (wooden and PVC);
soffit (vinyl and aluminum);
corrugated board.

Edged and planed board with a thickness of 1.5-2 cm is a practical material for mounting the filing, which makes it possible to ensure high-quality and uniform ventilation of the roof. To do this, the elements should be stuffed with a gap of 1-1.5 cm.

Wooden lining. This material should be chosen with great care: the roof eaves filing is operated outdoors, respectively, the lining must be made of high-quality medium-moisture wood and have a sufficiently large thickness - this will avoid warping.

It is recommended to use wooden lining that has been stored outdoors for at least a month, as its humidity corresponds to that of the environment.

PVC lining. It is an inexpensive and easy-to-install material. Moisture resistant lining is designed for a long service life. For the installation of this material, you should immediately purchase U-shaped plastic strips for sheathing the edges and special corners for attaching joints.

Soffit. This is a special aluminum or plastic panel with which the roof eaves are hemmed. Outwardly, the soffit resembles siding, but it is made of thicker plastic and is equipped with perforations, which allows you to create the necessary air ventilation under the roof. The advantages of aluminum and plastic soffit include high weather resistance and durability. UV stabilizers are added to plastic for the manufacture of spotlights.

Soffit panels are cut along the length of the cornice overhang and installed perpendicular to the wall.

Decking. Profiled sheet of galvanized steel with a color polymer coating is usually used for filing roofs made of the same material. The profiled sheet has a sufficiently high rigidity, is resistant to external influences and extreme temperatures. Corrugated board panels are cut according to the size of the cornice overhang. The ventilation gap of such a filing is equal to the height of the corrugated sheet wave.

Eaves sheathing frame

The roof eaves are hemmed after the roof frame is installed and the protruding edges of the rafters are adjusted to size. After sawing off the rafter legs, the first board of the crate is mounted along the line, which later serves as a guide for work in the following stages. Next, you should complete the sheathing of the overhangs, choosing the appropriate type of construction.:

Do-it-yourself filing of the roof eaves includes the creation of a roof overhang box. In both versions of the sheathing device, it is performed in the same way: a board is stuffed onto the crate along the gable, it is required to measure the distance from it, which should correspond to the width of the overhang. Then the board is nailed parallel to the gable wall.

Binder installation

Sheathing the roof eaves with soffit requires the use of a J-shaped strip, which is fixed with self-tapping screws along the eaves and along the wall. Soffit sheets are mounted between the slats. The length of each panel must be equal to the distance between the mounted strips minus 6 mm for thermal expansion of the material. If the roof overhang exceeds 900 mm, subtract 12 mm. The frontal board is closed with a special frontal bar. The use of soffit and special elements make it possible to create a durable, functional and attractive roof overhang.

Before sheathing the roof eaves with an edged board or wooden clapboard, the material cut to size should be impregnated with antiseptic, fire-resistant and water-repellent compounds. This allows you to extend the life of the binder.

The width of the edged board is adjusted depending on the size of the overhang. Elements should be mounted in 10 mm increments, creating ventilation gaps. If the cornice overhang is sewn up with clapboard, the planks are laid with a tenon-groove connection, and special ventilation grilles should be installed every 1.5 meters.

To sew up the roof overhangs with corrugated board, it is necessary to screw the pre-cut sheets to the frame parallel to the wall and along the eaves. Self-tapping screws are used as fasteners. The junction of the wall and sheet material is closed with an inner corner and a frontal bar. The inner corner should be attached to the profiled sheet, the frontal bar - to the frontal board. The fastening of the outer corner is carried out along the outer joints of the profiled sheet.

Along the pediment, the corrugated board is mounted along the wall, along the outer edge of the roof overhang. Then the corners and the end plate are installed. To provide air access for roof ventilation, the width of the corrugated sheet should be 2 cm less than the width of the overhang. It is important to bear in mind that the filing, made of metal sheet, is prone to corrosion in places where moisture accumulates and its service life is inferior to other options for finishing the cornice overhang.

Roof eaves filing: options and their features

One of the stages in the construction of any roof, giving it a finished look, is filing its overhangs or cornices, which protect the walls of the building. It can be made in various ways and using various materials, which have their own advantages and disadvantages. Therefore, in this article we will consider what the filing of roof eaves can be: options and materials used in this case.

When to do a roof overhang

There are two ways of filing roof eaves: before and after laying the roofing material.

It is best and most correct to file the roof overhangs before installing the roofing material, immediately after the construction of the wooden roof base (rafters, battens) and laying the waterproofing material. This is especially true in the case of modern roofing materials. At this stage, the brackets of the drainage system are also often fastened and the roof ventilation device is installed.

Previously, the filing of overhangs was done after the installation of the roofing material, and this was the final stage in the construction of the roof. And now this often happens, especially if the roofing material is asbestos-cement corrugated sheets or, in a simple way, slate. Sometimes this method is also used for roofing with other, more modern materials, such as metal tiles or corrugated board, in the case when there is no means to make both the filing of overhangs and the roof at the same time, or for other reasons. Sometimes the filing is performed after the external insulation of the facade, after applying the reinforcing layer, but before finishing.

Which option to choose, everyone decides at their own discretion, depending on the design of the roof, the type of roofing material, circumstances and availability of funds.

Roof eaves filing options

Currently, there are quite a few options for filing cornices (overhangs) of the roof, both in terms of the type of material used and the method of its fastening. For such a binder, the following materials can be used:

Each of these materials has individual properties that determine their advantages and disadvantages when used for filing roof overhangs. In order to choose the best option, consider their features in more detail.

planed board

Dry planed boards, 10-25 mm thick, treated with an antiseptic, are suitable for filing overhangs. At the same time, the boards can be laid and fixed both along the surface of the walls and perpendicular to them. The first option is most often used. It is convenient to fasten the boards to the crate with self-tapping screws using a screwdriver. It's better to work together. To ensure ventilation of the under-roof space, ventilation holes or slots are made in such a filing every 1-1.5 m.

Advantages of filing with boards:

Relatively low cost, especially in timber-rich regions;
Environmentally friendly material;
Simplicity and speed of work on filing the overhang, which allows you to do it yourself.

Not very presentable;
Boards have more weight than other materials and load the crate to which they are attached more heavily;
Wood, even treated and painted on the outside, can absorb moisture;
Boards can warp and twist over time;
Wood needs to be treated and painted periodically.

Roof eaves lining with wooden clapboard

Wooden lining differs from boards in its smaller thickness and the presence of a longitudinal sample for connecting to each other. For an overhang, it is necessary to use a lining that is dry and treated with an antiseptic. To ensure ventilation of the under-roof space, ventilation grilles are mounted in it every 1.5 m. The lining can be attached parallel or perpendicular to the wall. In the first case, the lining is attached to the crate every meter. In the second case, the elements are fastened along the edges, and with a wide overhang (more than 0.5 m), also in the middle. Fastening is carried out using nails or self-tapping screws.

The advantages and disadvantages of wooden lining are almost the same as those of planed boards. But the lining has a smaller thickness and weight. In addition, it has the best appearance and goes well with almost any type of roof and facade. But it is also more expensive than a board. The cost of high-quality wooden lining is from $ 4 per 1m 2.

Plywood or chipboard

Another option for filing the roof eaves can be moisture-resistant plywood or OSB chipboard. From sheets of such plywood or chipboard, strips of the required dimensions are cut out and, using self-tapping screws, are attached to the prepared crate.

Filing with these materials is simple and fast. But on the other hand, moisture-resistant plywood is not such a cheap material: the average market price is from $ 5, OSB boards - from $ 3.5. In addition, both plywood and OSB will have to be painted after filing.

Plastic lining

This is another fairly popular budget option for filing the roof eaves.

PVC lining is cut into pieces along the width of the overhang and attached perpendicular to the wall. It has insufficient rigidity, so it is not advisable to lay it along the wall. In addition to the lining itself, for filing the overhang, you will need shaped elements - fillets: U-shaped starting, H-shaped connecting, as well as external and internal corners. Fillets are attached to a wooden frame or crate using staples (stapler), kleimers or small carnations. Plastic lining is cut into pieces smaller than the width of the overhang by 4-5 mm and inserted into the grooves of the fillets. Depending on the width of the overhang, the lining is additionally attached to the wooden frame with brackets or clamps in 1-4 places. Since the PVC lining does not have perforations, for ventilation of the under-roof space, every 1.5 m of the filing, plastic ventilation grilles are installed in it. The average cost of plastic lining is small - from $ 3.5 per 1 m 2. Among the shortcomings, one can single out the low strength of the material and the tendency to burn out under the influence of UV radiation.

Hemming of roof eaves with a metal profile (profiling)

Decking or metal profile is a fairly durable material, as it is a specially curved (profiled) steel sheet coated with a protective layer. The latter can be in the form of galvanization or with an additional polymer coating. Most often, polymer-coated corrugated board is used, as it not only looks better and can be of almost any color, but is also more durable. The average cost of 1 m 2 of this material is from $ 7.

The advantage of corrugated board (metal profile), in addition to strength, is that it is laid in large planes (up to 1.2 m), it is lightweight and easy to install. But working with it requires care so as not to damage its protective layer.

The corrugated board for filing the roof eaves can have different ridge heights (from 8 to 20 mm) and sheet thickness - 0.4-0.5 mm. For filing the overhang, in addition to the corrugated board itself, you will also need shaped elements: profiles, strips, corners. Installation of profiled sheet strips is carried out in them with gaps of 0.5-1.0 cm, taking into account the thermal expansion of the metal. If these gaps are not enough to ensure reliable ventilation of the roof, then special ventilation grilles are mounted for this.

Hemming roof eaves with soffit

Soffits are essentially siding panels specially designed for filing roof overhangs. They differ from conventional siding in greater thickness and resistance to ultraviolet radiation. They can be vinyl or aluminum, non-perforated, fully or partially perforated to provide ventilation.

Soffits are much stronger than plastic lining. Their use does not require the installation of ventilation grilles - it is enough to use perforated panels. They are durable and do not fade in the sun. Among the shortcomings, the following can be distinguished:

Soffit panels are smaller than corrugated sheets;
Relatively high cost - on average from $ 9 per 1 m

You can even install spotlights with your own hands, especially if you need to hem a simple roof overhang. Due to their rigidity and strength, spotlights do not require a special frame for their installation. An exception can only be complex roofs with curved or multi-level elements.

For the installation of spotlights, additional elements are used:

From the side of the wall - U-shaped profile, which is attached directly to the wall or J-shaped, which is attached to a horizontal rail;
From the side of the end of the rafters or wind board - an L-shaped wind bar, which is attached so that its groove is in the same plane with the grooves of the J- or U-shaped profile;
To connect the soffits at the corners - an H-shaped connecting profile, which is attached to the carrier rail. Corner joints can be diagonal or at right angles.

Soffit panels should be 5-6 mm shorter than the distance between the grooves into which they will be inserted. In this way, it will be easier to insert them and thus their deformation during thermal expansion will be prevented. The elements of the filing are fastened with galvanized self-tapping screws with press washers. The panels are connected to each other with locking joints.

Sheet metal hemming

This is another option for inexpensive filing of roof eaves. For this, strips of sheet steel with a thickness of 0.5-0.8 mm can be used - galvanized or polymer-coated. Aluminum or copper sheets can also be used, but these are quite expensive.

Strips of metal are attached from below to a wooden frame or crate. For ventilation of the roof, perforation is made in the metal or ventilation grilles are mounted. Places of cutting steel sheets and their perforation must be treated with a special paint or anti-corrosion compound. The average price of steel sheet metal - from $ 4

Roof eaves filing: options and their features

What can be the filing of roof eaves: options and materials. Features of filing the roof overhang with soffit, profiled sheet and clapboard.

How to hem a roof eaves

After the installation of the roof, it is necessary to carry out work on its sheathing. The binder will perform three functions at once:

she will give the house a finished look;
provide roof ventilation;
protect the façade.

How to hem a roof eaves

Today we will talk about how to hem a roof eaves and what you need to use for this.

Varieties of overhangs

Front overhang

The main function of the front overhang is to protect the facade. In fact, these are the lateral edges of the roof slopes, therefore, the hip roof, which has 4 slopes, does not have such edges.

If we are talking about a gable roof (and in most houses it is), then the supporting beams installed on the rafters are released outside. It is also often possible to see an overhang from the boards of the lathing laid under the roof over the vapor barrier. The main cornice board is attached to them, which is subsequently sheathed (more on this later).

Side overhang

Every sloping roof has such an overhang. It is created by rafters extending beyond the walls of the building. The length of the protrusion depends on the blind area and the height of the building, but in most cases it is from 60 to 70 cm.

Despite the norms, sometimes there are narrower cornices. This can be fixed in two ways:

reliably protect the wall from the wind, because with oblique rain it will get very wet;
installing fillies to increase the length of the rafters is a more time-consuming procedure that few people want to perform (after all, you will have to open an already made roof).

Therefore, the required length of the cornice should be considered at the design stage.

Throughout the eaves, the rafters are fastened with boards - in the future they need to be covered with facing material.

How to make roof ventilation through filing

As already mentioned, cornices protect the roof and facade of the structure from precipitation. But at the same time, they should not become an obstacle to the natural ventilation of the space under the roof. And this applies not only to attics, but also to ordinary "cold" roofs.

The heated air, rising from below, must freely overcome the eaves, pass between the roof and the vapor barrier and exit through the ridge. That is why during the installation of the overhang, mounting foam or sealant should not be used, otherwise condensation will occur and, as a result, the insulation will get wet.

Note! Only the side cornices should be ventilated, while the front ones must be sealed tightly.

About the choice of materials for the overhang

Today there are a lot of materials for the eaves, each has its pros and cons. Nevertheless, all of them are very effective in providing ventilation and protecting the roof from moisture. When choosing one or another of the materials, pay attention not only to its appearance, but also to the service life.

Sheeting from corrugated board

This material is galvanized steel coated with polymer spraying. The corrugated board is resistant to heavy loads, temperature extremes, it has suitable rigidity. Between the layer of corrugated board and the surface of the wall, you need to leave a gap that would be equal to the height of the waves of the material.

Soffit lining

A more popular material used in the construction of roof eaves, which is nothing more than siding, but with ventilation holes. Another difference of the material is the use in the production of special ultraviolet stabilizers that protect the cornice from the harmful effects of sunlight.

Soffits are divided into several types depending on the material used in the manufacture.

A characteristic feature of copper spotlights is durability and presentability, but at the same time high cost. Such spotlights are very durable and non-flammable.

A characteristic feature of copper spotlights is durability and presentability.

Metal soffit is a sheet of high-quality galvanized steel coated with a polymer coating

Lining from lining

No matter what new materials appear, and even today, overhangs made of real wood are quite common. In this case, you need to carefully select the material, because the cornice will be located on the street and, therefore, be exposed to aggressive environmental influences. No need to save money and buy a thinner lining - try to make the material thickness at least 2 centimeters. Humidity lining should be medium.

Lining from lining

Note! Too wet lining is categorically not suitable, because it will definitely “lead”.

Boards should be nailed two centimeters from the wall to ensure good ventilation.

Methods for filing a cornice

You can hem the overhang using one of two available methods:

Methods for filing a cornice

The overhang along the rafters is only suitable for roofs with a slight slope. This method is complicated by the fact that as a result, the edges of the rafters must form a flat plane. This is not always possible, so the only way out may be small boards from the edge of the canopy to the wall, fixed to the rafters. To nail them evenly, you first need to pull the twine and align with it. For fasteners, use iron corners or screws.

Wooden box eaves are perfect for roofs with a significant slope. To build this box, you need to take a board 40 mm thick and fix it between the rafters and the wall surface. If one edge of the board is attached to the leg of the rafter, then an additional installation of a second board, vertical, will be required.

The box is finished, now you can start attaching the skin.

Note! It is necessary to fix the skin with screws, but not with nails - this will provide the necessary rigidity.

Soffit technology

The installation procedure consists of the following steps.

First stage. It is necessary to equip the spotlights with a pair of special strips in the form of the Latin letters F and L. The first must be fixed from the side of the cornice, the second - on a special rail attached to the wall. All fastenings are carried out using self-tapping screws. It is advisable to pre-mark everything so that the planks lay flat.

Second phase. Then you need to measure the eaves and subtract 6 millimeters from the resulting figure - this will allow you to make a gap to compensate for thermal expansion. Next, you need to cut the spotlights into strips of the required length.

Third stage. Soffits need to be bent a little and inserted into the installed profiles. Self-tapping screws are also used to fix them.

What you need to know when installing spotlights

It is undesirable to carry out work at temperatures below 15 ° C, even if manufacturers keep talking about the possibility of installation even in winter.
Soffits should only be mounted at an angle of 90°C.
Soffits should be stored only on a flat surface, in stacks of 15-20 pieces.
You should always leave a gap, as mentioned above.
To cut spotlights, you need to use a “circular” with a reverse tooth arrangement (you can also use special metal scissors).
The length of the screws must be at least 3 mm.
The step between the fasteners should be a maximum of 40 centimeters.

Technology of filing with corrugated board

First stage. First, a bar should be nailed to the wall in a horizontal position, strictly at the level of the overhang. In parallel, a second bar is attached at the same level, this time along the rafters.

Second phase. Then you need to cut strips of corrugated board (not forgetting the same thermal expansion) and attach them to the bars with screws.

Third stage. The joints are decorated with planks of the outer and inner corners.

Actually, the installation of corrugated board is completed.

Lining technology

The scheme of filing the overhang with clapboard

This procedure is preferably carried out from below, using a ladder or scaffolding.

Note! The cornice can be hemmed only after the completion of external insulation, installation of moisture insulation and cladding.

First you need to check if all the rafters have the same length and if they are installed parallel to the wall. Then you need to fix the wind boards on them and only after that proceed with the installation.

First stage. Screw the board to the wall in a vertical position. The bottom edge of the board should be flush with the rafters.

Second phase. Fasten the next board between the previous one and the rafters, lining up along the bottom edge. The result is a base - on it you need to install a crate.

Third stage. The frame is sheathed with boards. Traditionally, a slight gap should be left between them and the surface. The boards should be even, about 20 millimeters thick.

Note! To ensure ventilation, it is desirable to install special grilles every one and a half meters.

Although it is worth noting: few builders do this, relying on the fact that the tree has the ability to "breathe".

Conclusion

As a result, I would like to note that at the end of the installation, the installed material must be treated with an antiseptic agent - it will be additional protection for it. If you follow all the selection and installation instructions given here, then the curtain rod will stand for a long time and will look great.

Sheathing of roof overhangs: sheathing options and execution technique

The protection of the roof of the house and its attractive appearance are issues that require careful consideration. One of the possible solutions is a neat finish of the overhangs, which will reliably protect the truss elements from atmospheric influences and ensure the aesthetics of the roof.

The cornice overhang of the roof of a house is usually called its lower part, protruding beyond the boundaries of the walls. It is designed to protect the walls and the blind area of the foundation from getting wet during rain.

Hemming of roof overhangs according to the requirements of SNiP is not considered a mandatory operation. Nevertheless, many experts recommend not neglecting the filing of roof eaves. It will solve a number of important issues, for example,

in strong winds, ascending air flows arise, which, having penetrated under the overhang, tend to tear off the roof, and the filing of the roof overhang will become an obstacle in their path and will not allow oblique streams of rain to enter the under-roof space;
filing the roof overhang will hide the truss elements, the release of the layers of the roofing pie and the roofing from the attic side and more.

Finishing the roof eaves is the final stage in its construction, therefore, hemming the roof overhangs is performed after

her devices;
insulation and finishing of external walls;
drainage installations.

Types of overhangs

Eaves or side. These are horizontal overhangs that are formed by the lower part of the slope. Ventilation of the space under the roof also passes through them. After passing through the overhang, the air moves towards the ridge, drying the layers of the roofing cake along the way. Hence the conclusion that it is impossible to close them completely. But after all, it is also extremely undesirable not to sheathe the structure. So, you need to find a reasonable option, how to hem the roof overhangs, so as not to block the access of air under the roof, but for birds, insects or rodents - yes.
Fronton. They are formed by the sloping edges of the roof slopes and do not take part in under-roof ventilation. Therefore, the need to finish the roof eaves for gable overhangs is due to other reasons, namely the inclined plane of the structure. It is highly susceptible to the destructive effects of moisture, which is blown by the wind. This is especially dangerous for a mansard roof, since the edges of the insulation are not protected from getting wet. Gable cornices must be completely sheathed. Thus, the filing of the gable overhangs of the roof will become impenetrable.

How to finish the edges of the overhang

Both on the gable and eaves overhangs there are unclosed elements: the ends of the rafter elements and the end part of the lathing outlet, respectively, which must be finished before the roof eaves are hemmed.

The choice of material for finishing the edge of the cornice or its end part depends on the main material of the roof covering. Quite often, manufacturers supply ready-made edge finishing kits along with the roofing material. The sheathing process itself is performed according to one of the following algorithms.

All protruding truss elements or fillies are cut in one straight line strictly parallel to the wall, that is, vertically. Then the ends of the rafter legs are connected with a strapping board. A frontal roofing board is attached to it, the dimensions of which should allow the ends to be covered: completely or partially with a minimum shortage. It is on it that the gutters of the drain will be installed in the future.

The frontal board is made of metal or wood. For roofs made of tiles of known types, such a board is included in the set of roofing material. The frontal board is attached to the ends of the truss elements using galvanized nails or self-tapping screws.

The elements of the crate that protrude beyond its limits are cut parallel to the wall at the same level. An end board is nailed to them and tied to the end of the roofing beam. If the board is standardly fixed only to each element of the crate, then it will not be possible to achieve a sufficient degree of rigidity, therefore it is recommended to use a T-shaped connection.

To do this, additional elements are hemmed from boards or bars, placing them between the frontal board and two adjacent purlins, starting from the second, in increments of one interval, that is, every second and third are chosen.

Binder options

In principle, the filing of roof overhangs is performed by any convenient method. But on closer examination, all of them can be combined into two techniques.

One of the options for filing is directly along the truss elements. The main requirement in this case is the location of the open ends of the rafter legs in a single plane.

This method is suitable for roofs with a slope angle of not more than 30˚, the overhang of which does not exceed 0.4–0.5 m.
Hemming strips are stuffed onto the base of wooden parts nailed to the rafters.
You can sheathe the base both along and across.
Installation begins with the installation and fastening of the initial and last trim strip.
Then a building thread is pulled between them and, observing a verified level, the rest are put up.
When hemming the corner of two slopes, the planks must be fixed to the corner rafter on both sides.

Horizontal sheathing of roof overhangs is used on steep slopes. Installation of the roof eaves is quite fast.

A box is knocked down from wooden beams, which is attached to the adjacent wall and the base of the roof, and the wall beam must be placed 1 cm higher than the beam attached to the lower section of the rafter legs. Thus, they maintain the slope necessary for the flow of water that has fallen into the cornice due to the wind.
To ensure the rigidity of the box structure, the fastening of the bars with screws is duplicated with additional fasteners on metal plates and corners. Then proceed to filing it with some convenient material.

Various materials from metal, plastic or lumber are suitable for filing the eaves of the roof.

The most common is the filing of roof overhangs with a board 15–20 mm thick. The width of the material depends on the overhang of the cornice and ranges from 5–25 cm. The aesthetic appearance of the sheathing depends on the exact observance of the constant width of the boards.

The undoubted advantage of a board for filing roof overhangs is its ability to provide high-quality ventilation of the under-roof space, since the air in this case evenly enters there along the entire perimeter of the roof. The gap between the boards is 1–1.5 cm.

If the boards used for hemming are of sufficient length, they are screwed at several points to prevent deformation.
The boards are joined, adhering to a checkerboard pattern. In this case, it is necessary to leave a sufficient distance between the two joints.
The only exception is the corners of hip roofs, where the wooden planks are cut down when joined, dividing the right angle in half.
All elements are treated twice with antiseptics and fire retardants: before and after installation.

Another popular material is wood lining. Given the susceptibility of wood to all sorts of vagaries of the weather, special requirements are imposed on its quality:

strips should not have a small thickness;
humidity level. The natural humidity of the lining, which was stored in the open air for at least a month, is considered optimal.

The planks of the lining are laid tightly, leaving no gaps between them, as in the case of a board. Ventilation holes are cut out on the finished skin with a step of 150 cm, which are covered with gratings.

Sheathing of roof eaves with corrugated board coated with polymers is performed according to a simple algorithm.

When sheathing cornices with a profiled sheet, sheets of the desired size are preliminarily prepared. They are screwed to the finished frame parallel to the wall. For fastening use special screws.
The joint formed by the plane of the wall and the profiled sheet is closed by installing additional elements: a frontal bar and an inner corner. The corner is attached to the profiled sheet, and the bar, respectively, to the board. To close the external joints of the profiled sheet, use the outer corners.
The filing of the gables of the roof (photo above) is performed along the walls. Planks are fixed to the outer edge of the cornice and hidden under the end plank and corners. Sheathing strips should be approximately 2 cm narrower than the width of the overhang. Thus, the air intake will occur due to the height of the profile wave.
When installing the roof cornice, the profiled sheet can be finished in color by choosing the appropriate one from a variety of options.

PVC siding is a fairly affordable and effective option for filing roof eaves. This material often goes on sale in a special configuration. Plastic panels are supplemented with U-shaped strips, necessary for the design of edges, corners, as well as ventilation grilles. The sheathing is attached parallel to the edge.

Plastic strips are attached to a wooden frame at two to four points.

For filing the roof cornices, special plastic panels are produced - soffits. These panels are thicker than siding and usually have special perforations through which ventilation of the roof space passes. In addition, UV stabilizers have been added to the plastic for spotlights, which provide the material with high resistance to ultraviolet radiation. Soffits for filing are cut along the length of the cornice and installed at a right angle to the wall.

Sheathing of roof overhangs: sheathing options and execution technique

To give the structure of the house complete completeness, it is necessary to file the roof overhangs. Materials such as lining, board, siding,

Roof overhangs are filed for several reasons. One of the main ones is an aesthetic appearance, since the absence of spotlights gives the overall picture some incompleteness, and therefore the design is not accurate enough.

Manufacturers of modern building materials have taken care to make the process of arranging this section of the roof as easy as possible. If earlier various improvised materials were used to close the lower space of the overhangs, such as moisture resistant plywood, cutting boards, siding or lining, today on sale you can find special profiled sheets of certain sizes, as well as the necessary fittings for them. Due to the ease of installation of such parts, even a not very experienced craftsman who knows how to work with the simplest construction tools can install them. All you need is a screwdriver, an electric jigsaw or metal shears, depending on the material used to make the spotlights.

Naturally, when performing this type of work, it is necessary to observe appropriate precautions, since the main process will take place at a height.

Types of spotlights and their design

The word "soffit" is translated from Italian (" sofitto”) as “ceiling”. These parts are panels made of metal, wood or plastic and are intended for filing eaves and gable roof overhangs, as well as other horizontal surfaces. In terms of their functions, they can be compared with such popular materials today as siding or lining. However, these panels have a number of differences that take into account the scope of their application. And one of them is their width, which can even reach up to 800 mm.

Soffits are divided into types according to various criteria:

- according to the design features;

- according to the material of manufacture;

- by area of application.

Design features of soffit panels

According to their constructive structure, spotlights are of three types - they are perforated, partially perforated and completely closed.

Perforated the variant is a panel that is evenly covered with small through holes over its entire surface. This type of material is intended for filing horizontal surfaces of overhangs that do not fall under the direct action of atmospheric precipitation. Perforation is able to provide effective ventilation not only for the overhangs themselves, but also for the entire under-roof space of the roof structure. A constant air exchange must be provided here. This is necessary to prevent the accumulation of condensate, dampness, and as a result, the onset of putrefactive processes on the wood and the appearance of mold or fungus.

Perforated panels perfectly protect the space under the overhangs from the penetration of birds and insects (for example, wasps) into these cavities under the roof, since the holes have a very small diameter.

Partially perforated panels have ventilation holes not over the entire surface, but only on one or two sections of the profiled sheet. Thanks to such hemmed materials, it becomes possible to adjust the air exchange in a peculiar way. Partially perforated soffit panels are used for filing the external horizontal surfaces of the house, as well as the ceilings of terraces, gazebos, verandas or porches. Therefore, this type of material can be called universal.

Non-perforated the panel variant does not have holes on its surface, and is intended for sheathing areas that, with a high degree of probability, can be directly exposed to precipitation. Such areas may include overhangs on the gable part of the roof, as well as vertical walls along the eaves. In addition, soffits without perforation can be used for facing the vertical part of the gable.

Everything except wooden homemade soffit panels , howplastic, and metal, have special locks with which they are fixed on the overhang and connect with each other. After the spotlights are docked and fixed oncrate overhang, locks it is seen will not.

Standard sizes of vinyl and metal soffit profiled panels can vary in width from 300 to 800 mm, and their length usually is 3050 mm.

If the work on filing will be done independently, then it must be taken into account that the wider the panel is selected, the faster the installation can be carried out soffits in place.

Varieties of spotlights according to the material of manufacture

According to the material of manufacture, as mentioned above, finished spotlights can be divided into plastic and metal (steel, aluminum and copper) options. Sometimes natural wood is also used. To determine the choice of soffit panels according to the material of manufacture, it is worth considering their characteristics in more detail.

Plastic (vinyl) panels

Plastic spotlights are made from the same composition of material as for finishing facade walls.

The service life of such plastic in outdoor conditions declared by the manufacturer is 30 years or more, which, you see, is very long. It is easy to look after it - it is enough to periodically clean it from dust. The material does not require dyeing, as it has a constant color - the dye is introduced into the vinyl structure at the stage of production of the plastic itself. In specialized stores, a wide range of panel colors is presented, which allows you to choose the one that will be in harmony with the shades of the facade color and the color of the roof. The panels are sold in packs of 16÷22 pcs.

The group of metal spotlights includes panels made of aluminum, steel and copper. However, the most popular of the metal panels are steel as the most affordable. The second place is occupied by aluminum, and after it comes copper, but not because of low quality, but because of the high cost.

Each of the metal options has its own drawbacks.

It has already been said that the most affordable of metal panels are steel spotlights, which have an enamel protective and decorative coating. After cutting the parts for filing, the cut edges require processing, otherwise, with the inevitable exposure to moisture, they will become centers of the appearance and further development of corrosion.

Aluminum can also be damaged by oxygen corrosion, and to prevent this from happening, its cut must also be treated with a special compound.

Copper, although it has the highest cost, is also subject to oxidation. Therefore, the material for these products is often subjected to an oxidation process. True, the oxidation of copper does not lead to a violation of the structure. Therefore, such products are often considered as not having any limited shelf life.

Copper panels are becoming more expensive due to the fact that they are usually purchased with a drainage system made from the same material.

The positive characteristics of metal soffits include the following qualities:

A wide range of colors for steel and aluminum soffits.
A very presentable appearance of the copper version of the sheathing of the cornice overhangs, especially if it comes in combination with a copper roof.
With appropriate processing of cuts, the material becomes resistant to atmospheric aggressive influences.
Complete inertness to the occurrence of fungus, mold, moss, to biological decomposition.
material strength and quite high resistance to mechanical damage.
Inert to ultraviolet radiation and temperature extremes.
The operating temperature range lies in very wide limits - from - 60 to +100 degrees.
The material is environmentally friendly, does not emit toxic fumes.
The relatively low weight of the materials facilitates installation work. In addition, due to this quality of the material, it can be used on old buildings. Such decorative sheathing slightly increases the load on the supporting structure.
Easy care for the created design.
Long service life, which should be at least 30 years for steel and aluminum. They have already said about copper - there are no special restrictions on the duration of operation.

Wooden spotlights

Quite often on wooden and stone buildings you can see overhangs hemmed with boards or wooden planks. Home craftsmen most often make such spotlights on their own. Another option is to order them in carpentry workshops.

However, when choosing this material for filing overhangs, do not forget about the need for ventilation. To ensure it, gaps are often left between the wooden planks, and so that insects cannot settle in the under-roof space, a metal mosquito net is fixed to the overhangs before fixing the narrow boards.

Planks of wooden spotlights can be fixed along the cornice or perpendicular to it. Their location depends on the choice of the owner of the house, the overall design of the facade and the width of the roof overhang.

Additional structural elements of the filing of cornice overhangs

When installing soffit panels, additional profile elements will be required, which play not only a functional, but also a decorative role. For soffits, fittings from the kit used when facing walls and other surfaces with siding or plastic clapboard are used.

To frame and fix the edges of the panels, a J-profile is fixed on the crate of the plumb lines, which can have different widths, depending on the model of the kit.

Siding prices

A finishing strip is used to decorate the upper edges of the panels fixed to the windboard. It is the final element of the design. This element is fixed along the upper edge of the wind board and the edge of the panel is hidden in it.

The H-profile is necessary for joining individual panels in places where it is impossible to use locks located along the edges of the spotlights. For example, you can’t do without it when decorating the corner zones of cornice overhangs.

The use of the H-profile simplifies the diagonal mounting of the panels and masks their unevenly cut edges. In addition, the H-profile must be installed between the panels in cases where the eaves overhang has a length of more than 8000 mm. The connecting element will give rigidity to the structure and make it more reliable.

To install soffit panels on the wall of the building, not only J-profile is used, but also F-profile. It is convenient in that it fixes the panel not only from below, but also from its upper part. In this profile, fixed along the line of the wall, the panels slide in and are firmly held in one position.

The profile, called the outer or outer corner, is usually mounted at the junction of the lower edge of the wind board and the overhang crate, into it installed windboard cladding panels and overhang soffits.

In addition, the outer corner can be used in other cladding areas where two panels need to be joined at the corner line.

Inner corner - this profile will be necessary if the house has an L-shaped or U-shaped layout in plan, and also if the porch, veranda or terrace of the house protrudes beyond the main building.

The inner corner is also suitable for joining soffit panels and siding boards or lining used for wall cladding along the wall.

J-bevel - great for cladding the front board, at the same time creating conditions for attaching soffit panels

J-bevel is a wide profile, the bottom edge of which is S-shaped. It is designed to install the front edge of the soffit panel into it. This profile element can be used when installing spotlights if there is a wind (frontal) board in the overhang design. When choosing the size of this profile, it is necessary to focus on the width of the windboard.

An example of using a similar J-bevel is well shown in one of the illustrations above.

Additional fittings for mounting spotlights are selected depending on the design that the eaves overhang lining will have. Sometimes different profiles can be interchanged. For example, instead of an internal corner, two J-profiles are installed, turned in different directions. However, it is best to use the profile element that is directly intended for a particular area of joining or framing panels.

In order not to miss any of the elements for mounting the structure when purchasing material, it is recommended to draw up a diagram in advance and measure the length and width of the surfaces of the overhangs and the windboard. In a hardware store, according to the drawn up scheme, the sales assistant will help you decide on the choice of sizes and shapes of profiles, as well as their length and quantity.

Soffit panel mounting options

How the soffit will be installed depends on the width of the overhang, that is, on the distance that has formed from the wall to the end of the rafter (or filly), and also, often, on the height of the latter.

If the width of the overhang is less than 400 mm, then the soffit panel can be installed in profiles fixed horizontally on the wall of the house and at the ends. In this case, additional crates are not even required.

If the width of the overhang is more than 400 mm, but less than 500 mm, then along the entire perimeter of the overhang, a bypass rail or beam is fixed to the ends of the rafters, to which J is fixed - a profile into which the edges of the soffit panels will be installed. Such a strapping will strengthen the overhang and become a place for additional fastening for spotlights. That is, the step of their fixation will be less, which means that they will hold on more securely.
If the overhang has a width exceeding 500 mm, then it is necessary to mount a crate under the soffit panels. To do this, bars are fixed on the wall, as well as on the edges of the rafters, and then between them, along the entire length of the overhang, resulting in a reliable basis for the panels. Guide profiles are fixed on the bars fixed along the edge of the rafters and on the wall - which one to choose is determined in advance. In these profiles, soffit panels will be installed and fixed. It turns out that each of the panels will be fixed at six points.

If the wind board has a small width, then one long, but narrow one, which is installed along the roof overhang, can be used for its sheathing. If the frontal board has a width of more than 150 mm, then the panels are recommended to be fixed vertically. Regardless of how the panels will be installed, before installing them, it is necessary to fix the corresponding profiles under the roofing material, as well as along the edge of the rafters.
Here it is worth considering the design of the corner zones of the plumb line. They can be sheathed at an oblique or right angle, as shown in the figure.

Soffit connectors at roof corners:

a) an oblique angle;

b) right angle;

1 - external receiving cornice profile - J-profile or J-chamfer

2 - soffit panel;

3 - two J - profiles installed "back to back", or one H-profile;

4 - wall profile: it can be F-profile or J-profile;

5 - J-profile, as an additional supporting element, mounted when forming the filing at a right angle.

Sewing cornice overhangs with soffits - do it yourself

Assembly tools

To carry out installation work on filing cornice overhangs, it is necessary to prepare the following tools:

Building level.
Roulette, ruler, construction square.
Miter box.
Hammer and
"Bulgarian" and (or) metal scissors for metal panels. It is still recommended to use scissors, since when cutting sheet metal with an abrasive disc, the edges of the panel lose their protective coating due to overheating, and corrosion centers cannot be excluded in these areas.
Hacksaw for wood with fine teeth for plastic and wooden spotlights.
Sharp construction knife.

Having these tools at hand, and knowing how to use them during the installation process, you can easily cope with the task of filing spotlights.

Installation procedure

By themselves, the installation of soffit panels is not particularly difficult. The problem may, however, be the fact that the main operations will have to be carried out at a height.

Therefore, professional builders, before proceeding with the installation of the drain and sheathing of the roof overhangs, install scaffolding along the entire length of the slope. it rather complicated construction, but allowing you to move around calmly and do all the work alone.

If it is not possible to use the scaffolding, and you will have to work from the stairs, then you will need two of them, and you will also have to invite an assistant.

So, work on arranging the spotlights begins after the flooring is completed. The first step is to measure the overhang area: you will need to find out its width, length and width of the wind board on both sides of the roof. If it is planned to cover the gable overhangs or even the entire gable, then the dimensions are also taken from it.

Illustration	Brief description of the operations performed
	According to the measurements taken, a scheme is drawn up for filing the overhangs, indicating the dimensions and locations of specific profile elements. In addition, it is immediately necessary to determine the elements of the crate. Above it was told about the standard schemes of the wooden base for the installation of spotlights. However, some craftsmen, for the purpose of higher reliability, prefer to reinforce the crate with additional bars. These elements are also included in the scheme, and then in the estimate. The overhang filing scheme may look like the one shown in the figure, but it would be additionally useful to mark on it the dimensions of the length and width of the sheathed area. Having a scheme for the execution of work, it will be easy to plan the purchase of materials and accurately calculate the costs.
	Having purchased everything you need, you can proceed directly to the execution of work. And the first step in this process is fixing the crate. The most common way to arrange the crate, even if the overhang has a width of 400 mm, is to form a frame from three longitudinal bars. One of them is fixed to the wall with dowels or other fasteners at the level of the lower edges of the rafters, and the second is fixed to the lower ends of the rafter legs with self-tapping screws.
	The average guide of the crate in different versions can be attached in different ways. For example, if the length of the slope is small, then the timber fixed in the middle part of the structure can be fixed only along the edges of the cornice overhang. If the length of the slope is more than two meters, then the middle beam must be fixed not only along the edges of the slope, but also in addition to the rafter legs, by installing sections of the beam between them.
	At the corners of the roof it is necessary to make a reinforced crate. In this case, of course, it takes into account how the soffit panels will be joined - by direct or oblique connection. If the second option is chosen, then it will be necessary to fix the beam from the corner of the house to the outer corner of the overhang. An H-profile will be fixed to this frame element.
	It is much easier to equip the crate for spotlights, which will be fixed parallel to the rafters. In this case, two or three beams, depending on the width of the overhang, are fixed directly to the rafter legs (or to their continuation - filly).
	A J-profile (starting profile) is fixed to the lathing beam, fixed along the wall, with self-tapping screws. Fastening is carried out with a step of self-tapping screws of 150 mm. Here it is necessary to take into account that if the walls are sheathed with clapboard or siding, then instead of the J-profile, an inner corner bar is installed. Instead of a J-profile, an F-profile can also be installed, which will more securely fix the panel in the required position.
	A J-profile can also be installed on the front side of the frame. However, to make the task easier, you can immediately install a J-bevel instead, which will close the windboard and become a support for the front side of the soffit panels. If this element is selected for installation, then first a finishing profile is installed along the top line of the windboard, which will hold the J-bevel panel. The illustration shows the installation of these parts on the elements of the crate and the wind board. On it you can see: 1. Finish profile. 2. J-bevel. 3. Wind board (prichelina). 4. Wooden frame element. The installation of all these parts is carried out using self-tapping screws, which are screwed approximately into the middle of the longitudinal holes and are not tightened to the stop. It is recommended to choose stainless fasteners that will last longer and will not leave rust stains on fittings and soffit panels.
	The next step is cutting the panels according to the dimensions of the overhang width taken in advance. Metal soffits are cut with metal shears. The illustration shows cutting using a grinder, but we have already mentioned the undesirability of this approach when using steel spotlights above. Vinyl panels can be easily cut with a fine-toothed hacksaw. When cutting panels, it must be taken into account that the panels must be 6÷7 mm less than the full width of the overhang, that is, the so-called technological gap must be observed. Such a value is necessary if the panels are not pushed into the profiles from their end side, but are inserted first into one, fixed along the wall, and then into the J-chamfer. In addition, this gap will allow the material to expand as the ambient temperature changes. It should be noted that each of the materials has its own temperature gap, which is indicated by the manufacturer in the soffit installation instructions. The edges of the cut metal spotlights must be immediately treated with anti-corrosion compounds, otherwise corrosion will begin to destroy the panels over time, and they themselves will take on an unsightly appearance from rust streaks.
	Next, you can proceed to install the spotlights in the profiles prepared for them. If J-chamfer is selected for installation, then the soffit panels slide into the gaps of the profiles.
	Each of the retracted panels is screwed to the wooden crate through special longitudinal holes. The next installed panel is inserted into the locking part of the previous one, that is, it covers the edge with holes through which the first one is fixed to the crate. So the installation continues to the corner of the overhang.
	If it is more convenient to install and fix the spotlights on the crate into the profiles, inserting them first into the guide fixed on the wall, and then into the front one, then this process must be carried out very carefully, since the edges of the profiles can be easily damaged. This installation method is more suitable for vinyl panels, as they are more flexible and easily return to their original shape after a slight bend. After installing the first panel, it is immediately screwed to the crate in two or three places, depending on its width. The next panel is hooked to the first one by the bent edge of the locking part and closes the chamfer with fasteners.
	If the overhang does not turn to the other side of the house, then for its side part, parts are cut out from a solid (without perforation) soffit or siding panel, which are fixed on the end part of the crate. These parts can be mounted vertically or horizontally, but in such a way that rainwater cannot penetrate under them at the junctions. The illustration shows only the crate for installing such a "plug".
	If for the design of the corner zone of the overhang the method of direct fastening of the panels is chosen, then the overhang of one of the sides of the roof is hemmed in the usual way, and on the second side the panels are fixed with a profile pattern perpendicular to the panels of the other side of the overhang. If, as shown in the illustration, the overhang has a complex shape, then the spotlights are fixed on it, according to the installed crate, the design of which will have to be thought further, based on specific conditions.
	If you want to form a sheathing on the so-called "oblique corner" or "herringbone", it is necessary to provide a beam in the frame crate, which is installed in the corner part from the wall to the outer edge of the overhang. In the future, an H-profile will be fixed to this element, into which panels cut at an angle of 45 degrees will be installed, forming a right angle of the overhang.
	The gable overhang is much easier to deal with, as it usually has a small width, and two types of profile can be used to frame its edges - this is a J-profile and an F-profile. An internal corner profile is often used to join panels under the ridge. If the gable side of the roof is sheathed with clapboard, then one profile can be used for it and soffits - this is an internal corner fixed along the line of intersection of the slopes and the gable wall. A soffit panel is inserted into one side of this profile, and lining or siding into the other.

Common errors when filing roof overhangs with soffits

To make the overhang look neat, it is necessary to follow the sequence of the installation process. Even a slight deviation or simplification can backfire.

Prices for lining

Do not neglect additional elements in the frame crate, as well as save on fasteners. A strong wind that has risen can easily spoil the whole work, tearing off and breaking the soffit panels if they are not fixed securely enough. As a result, money and time will be wasted, and the same work will have to be done again, impoverishing the family budget for additional waste.
Soffit filing is carried out after the walls are lined with clapboard or siding, and gutters are installed.
It is recommended to fasten all parts of the soffit construction only with stainless fasteners. Otherwise, after a very short time, the initially neat appearance of the finish will be radically spoiled by rust spots.
Soffit panels made of any material during installation require compliance with the technological gap, since when the temperature rises and the material expands, it can be deformed. The lining in such cases begins to warp, and it has to be dismantled in order to redo it later.

Adhering to all the rules and recommendations for the installation work, as well as strictly observing the necessary safety measures, it is quite possible to file the cornice overhangs with spotlights on your own, without resorting to the services of craftsmen and saving a very decent amount.

You can familiarize yourself with some additional nuances of filing overhangs with spotlights by watching the video recommended for attention:

Video: the process of installing spotlights on roof overhangs

When the installation of the roofing is completed, work begins on the sheathing of the roof overhang. This is done not only to protect the facade and ensure ventilation of the roof, but also to give a finished appearance to the building. The article will talk about what materials are used for these purposes and how the roof eaves are hemmed with soffit, corrugated board and wooden clapboard.

Roof eaves device

The eaves overhang is the protrusion of the rafters outside the facade of the house. It can be both simple and with removal. The first one is simpler in execution, and with a strong wind it will not be unpleasant to buzz in it, which cannot be said about the second option.

Roof overhang assembly

1- Gutter;

2- drip;

3- metal apron on the frontal board;

4- self-tapping screw;

6- bar 5x5 cm;

7- rafter leg (filly);

8- hemming material;

9- break;

10 - boards that are the basis of the cornice overhang;

11 - support bar for fixing breaks.

There are two types of cornice overhang - side and front.

Frontal roof eaves

Front is needed to protect the facade of the house. It represents the lateral edges of the sloping roof slopes. Accordingly, they are absent from the hip (four-pitched) roof.

The device of the front overhang of an ordinary gable roof is carried out by releasing the bearing beams fixed on the rafters. It is often possible to meet when the frontal cornice is formed by sheathing boards, which are laid on the vapor barrier under the roofing material. A cornice board is attached to them, which will later be sheathed with corrugated board or soffit.

Side roof eaves

All sloping roofs have a side overhang. It is formed by rafters that protrude beyond the walls of the house. The distance of their protrusion is calculated from the height of the house and the width of the blind area, often it is about 50-70 cm.

Although it is believed that the minimum allowable overhang size is 50 cm, there are also narrower ones.

In this case, the wall of the house must necessarily have good wind protection, since it will get very wet under slanting rain.
The second option to correct the situation is to install fillies, thereby increasing the length of the rafters. But this is a rather laborious process, and with the roof already made, few people want to open everything and redo it again. Therefore, it is important to provide for the required size of the roof overhang even at the construction stage.

The rafters are interconnected by boards along the entire length of the eaves. In the future, they will be covered with facing material.

Creation of proper ventilation of the roof through the cornices

The main function of any eaves is to protect the roof from atmospheric influences. But at the same time, it should not interfere with the natural ventilation of the under-roof space. This is important not only for residential attic floors, but also for cold roofs. The warmer air rising from the ground must pass through the eaves unhindered and, moving between the vapor barrier and roofing material, go out through the ridge. It is for this reason that it is forbidden to use various sealants and mounting foams when filing the eaves. Otherwise, condensation will form, which will lead to the wetting of the roofing insulation.

But there are exceptions here - eaves are made ventilated only under the roof slopes, and all front overhangs are closed “tightly”.

The choice of materials for filing roof overhangs

To date, there is a wide range of materials for filing the roofing cornice. Of course, each of them has its own advantages and disadvantages, but all of them fully protect it from moisture, provide insulation and ventilation of the roof. When making a choice in favor of a particular material, one should be guided not only by its beautiful appearance, but also by the length of its service life.

Decking

It is galvanized steel with a multi-colored polymer coating. It is resistant to mechanical damage and temperature extremes, has the necessary rigidity, and is also not afraid of wind loads. To provide the necessary ventilation, a gap is made between the corrugated board and the wall of the house equal to the height of its wave.

Soffits

This is the most popular material specially designed for filing cornices. In fact, these are plastic panels that look like siding, but already have ventilation holes. They also differ from ordinary siding in that they contain UV stabilizers that protect the spotlights from the negative effects of sunlight.

Copper spotlights

This is a durable material, outwardly very aesthetic and presentable, but also quite expensive. Soffits made of copper have high fire-resistant and strength characteristics.

Aluminum spotlights

They are very light, fire-resistant, elastic, and if necessary, their repair is not difficult. They also have high color fastness, so that the color saturation does not change under the influence of ultraviolet radiation.

The only drawback is the scarcity of colors - they are produced in white or brown.

Galvanized spotlights

They are durable and do not require additional care. These are durable spotlights that are not afraid of moisture and fire. But they are quite heavy, which to some extent makes their installation more laborious.

Vinyl spotlights

This is an inexpensive and most popular soffit option for filing roofing cornices. They are light in weight, perfectly protect against environmental influences, have a noble appearance, are easy to install, and also create a seamless canvas, providing full ventilation of the under-roof space.

Today they are made of fire-resistant plastic, which, moreover, is able to withstand severe loads. Three types are produced:

solid three-lane without ventilated holes;
fully perforated;
three-strip with a perforated center strip (the most popular).

Regardless of the material chosen for the spotlights, they are all fairly easy to install, and such work will not be difficult even for a beginner in construction. The basic rule when installing them is that they are located perpendicular to the wall, and not along.

Wooden lining and edged board

Until now, it is often possible to find that real wood is chosen for filing the cornice overhang. Since it is installed outside the house and is exposed to aggressive environmental influences, the choice of material must be approached responsibly. You can’t save and buy a lining that is too thin, its optimal thickness is 2 cm. It should also be of medium humidity (too wet will not work, as it can “lead”, but very dry is also not the best option).

To ensure ventilation, the boards are nailed with a 2 cm indent from the wall.

Sheathing of the roof overhang on the rafters

This method is rational for roofs with a small angle of inclination. The complexity of this execution of the sheathing lies in the fact that all the edges of the rafters form a flat plane.

But this can be achieved forever, then the way out will be small boards that are attached to the rafters. Their length is equal to the distance from the wall of the house to the edge of the overhang. To install them evenly, first one board is screwed from each edge of the eaves and twine is pulled between them. According to the received landmark, all other segments of the boards are attached. Sheathing to such a frame is attached to metal corners or screws.

Roof overhang filing on a wooden box

This method is ideal for roofs with a large slope. To equip such a box, a 4 cm thick edged board is taken and fastened between the wall of the house and the edge of the rafters. If one of its edges is installed directly to the rafter leg, then to fix the second edge, you will need to install a board adjacent to the wall, which is screwed to the rafters from above.

A second option is also possible, when instead of an additional vertical board, a beam is attached to the wall of the house with dowels.

On this, the frame of the box is completed, and the skin can be attached to it. To ensure the necessary rigidity of the entire structure, everything should be fixed not on nails, but on screws or corners.

Hemming of cornice overhangs with soffits

Stages of work:

Soffits are completed with two special strips, which have the shape of the letter J or F. One of them is attached to a wooden rail prepared on the wall of the house, and the second from the side of the overhang. Self-tapping screws are used as fasteners. All planks must be attached absolutely evenly in relation to each other, so it is recommended that you first make a markup.
Then the width of the eaves overhang is measured and 6 mm is subtracted from the result. This is done in order to create the necessary gap, which compensates for the thermal expansion of the material. Soffits are cut into strips of the desired length.
The prepared plates are slightly bent and inserted into the grooves of the installed profiles. Where are they fixed with screws.

In order to hem the corner of the eaves, the length of the soffit strips must be gradually reduced, cutting off one of the sides at an angle of 45 degrees.

For their connection, an H-profile or two J-profiles are used.

For more detailed instructions on how to hem a roof eaves with spotlights, see the video below.

Important points in working with spotlights

The soffit is attached only at a right angle and through special holes;
there must be a gap so that the panel can expand or contract unhindered;
optimal size of fasteners: leg length 3 mm, cap width 8 mm. They should not be screwed tightly, but have a gap between the cap and the surface of the soffit equal to 1 mm;
the distance between the attachment points is 40 cm (more often);
soffits are cut using a circular saw with a blade on which the teeth are located in the opposite direction. You can also use scissors for metal or a knife. In the latter case, it is best to draw the place of the incision with it, and bending the panel along it, break off the required segment;
it is necessary to store and transport spotlights on a flat surface in low piles (packs of 10-15);
despite the fact that the manufacturer assures the possibility of installing spotlights even in winter, it is not recommended to carry out work if the temperature is below 15 degrees.

Sheathing of roof eaves with corrugated board

First, a bar is nailed to the wall in a horizontal position at the level of the edge of the overhang. At the same level with it, a second bar is attached along the edge of the rafter legs;
the corrugated board is cut to the required length (not forgetting the thermal reserve of the material and the need for a ventilation gap) and attached to the installed bars with self-tapping screws;
the junction of the profiled sheet and the wall is closed with an inner corner bar, and the connection of the outer edge with the rafters is decorated with a similar outer corner bar.

This completes the installation of corrugated board.

Roof overhang filing with wooden clapboard or board

It is most convenient to file roof overhangs from below, standing on scaffolding or on a stepladder.

Important! The eaves should be hemmed only after the walls of the house are completely insulated from the outside, a vapor barrier is made and the installation of the facing material is completed.
