The main elements to ensure the normal temperature and humidity regime of the roof are vapor barrier, insulation of the required thickness (depending on the region), windproof material, ventilated under-roof space.
Flexible shingles with the same color codes and manufacturing dates should be used on the same roof. Shades of shingles from different batches may vary slightly. To avoid color imbalance, Euromet specialists recommend mixing tiles from several packages before installation. To make it easier to separate the shingles from each other, the package can be slightly bent and shaken before opening.
If the roof is being installed at a temperature below +5°C, the tiles must be stored in a warm room before installation. The self-adhesive layer of the material must be heated with a thermal (construction) hair dryer.
When cutting a soft roof, a special board should be placed under it so as not to damage the bottom coating.
During storage, Shinglas bituminous tiles should be protected from direct sunlight, since under their influence the adhesive layer can sinter with the protective film. Pallets with material cannot be stacked on top of each other.
You should not walk on the roofing in sunny and hot weather, it may leave marks and stains from shoes. It is recommended to move along the roof using special manholes.
Materials used
shinglas
Flexible tile SHINGLAS differs from similar products of other Russian manufacturers in a wide range of colors and cutting shapes. Currently, about 50 different models of Shinglas shingles are presented on the domestic market.
Lining carpet TechnoNIKOL
Self-adhesive backing materials:
- ANDEREP ULTRA is a high strength, self-adhesive underlayment. High reliability of the material is achieved due to a strong polyester base and high-quality bitumen-polymer binder. The upper protective layer of the lining carpet is made of fine-grained sandy dressing.
- ANDEREP BARRIER is a baseless self-adhesive material. A thick reinforcing film is used as the top protective layer. The absence of a base allows you to maintain the integrity of the waterproofing material in case of deformation of the base.
Lining materials with mechanical fixation:
- ANDEREP PROF has a durable polyester backing and a non-slip polypropylene top cover. Thanks to a special bitumen-polymer mixture, the material can "self-heal", that is, it maintains tightness at the points of entry of nails.
- ANDEREP GL is a lining material with two-sided protection of the polymer mixture by layers of fine-grained sandy dressing.
Valley carpet TechnoNIKOL
The TechnoNIKOL valley carpet is a rolled bitumen-polymer material. Made on the basis of polyester, has a protective coating of coarse-grained basalt granulate. It is used as a waterproofing layer in valleys and places that are subjected to the greatest loads.
Adjoining planks, eaves and gable overhangs
Metal elements with a special protective (anti-corrosion) coating.
roofing nails
Special galvanized nails are used. The diameter of the nail leg is from 3 mm, the caps are from 9 mm, the length is 25-30 mm.
Mastic TechnoNIKOL No. 23 (FIXER)

Consumption of roofing material
Tiling. Each package of the Shinglas soft roof of the "Country" and "Jazz" series contains the amount of tiles sufficient to cover 2 m 2 of the roof (including overlaps). In packages of Shinglas shingles - per 3 m2 of roofing. The calculation of the amount of material should be made taking into account the coefficient, the value of which depends on the complexity of the roof. The waste rate of bituminous tiles with the "Accord", "Sonata", "Dragon's tooth" cutting forms, together with the ridge-cornice tiles, is up to 5%. For the rest of the tiles, when calculating the amount of material, a waste rate of 10-15% should be taken into account (including the consumption for the starting strip, ridges and roof ribs).
Roofing nails. The required number of roofing nails is determined at the rate of approximately 80 g per 1 m 2 of the roof.
Mastic TechnoNIKOL No. 23 (FIXER). 400 g of mastic per 1 rm is spent on the valley carpet, 100 g per 1 rm on the end parts, about 750 g per 1 rm for sealing the joints. 1 mm, this can lead to smudges and swelling of the material.Preparing the roof base for installation
1. Device for laying under flexible tiles
Quite strict requirements are imposed on the base for soft tiles. It must be rigid, solid and even (differences in height of no more than 1-2 mm are allowed). Large-panel flooring is laid with a spacing of seams; self-tapping screws or nailed nails are used to fix it. When installing wooden flooring, you need to pay attention to fragments of annual rings and lay the material so that they are facing downwards with bulges. If the installation of the base from OSB-3 or plywood is carried out in the cold season, a gap of 3 mm should be left between the sheets. This will avoid deformation of the flooring during the thermal expansion of the material in the summer.
Before installing the plank flooring, it is necessary to pre-sort the boards by thickness. They are laid so that the thickness of the base changes gradually. At the same time, thicker boards are laid closer to the eaves, and thinner ones near the ridge. The joints of the boards should be located on supports, in these places the boards are fixed with at least 4 nails. If wet wood is used, the boards are fixed with 2 self-tapping screws on each side.
To reinforce the cornice overhang, metal cornice strips are used. These elements protect the roofing material in the eaves zone from the effects of precipitation. Cornice strips are attached to the edge of a solid base with roofing nails. Nails are hammered in a checkerboard pattern at a distance of 12-15 cm from each other. The planks are overlapped, the width of the overlaps should be 3-5 cm. In the places of overlaps, nails are hammered in increments of 2-3 cm.
The lining carpet for any slope of the roof is mounted over its entire area. In the area of cornice overhangs and in valleys, ANDEREP self-adhesive lining material or other similar material is laid. It serves as an additional protective coating in areas of the most probable leaks.
On eaves overhangs, the width of the self-adhesive underlayment must be 60 cm greater than the width of the eaves. The width of the eave projection is measured from the plane of the inner side of the outer wall of the building, as shown in the figure. The bottom edge of the carpet should be 2-3 cm above the edge of the eaves strip.
In the valleys, a self-adhesive lining carpet 1 m wide is laid (each slope is covered by 50 cm). It is desirable that the carpet be continuous along the entire length of the valley. In the case of using two or more canvases, they are overlapped. The width of the overlaps should be 30 cm, the seams must be carefully glued.
The lining material with mechanical fixation ANDEREP or other similar material is mounted on the rest of the roof surface. Cloths are laid parallel to the cornice overhang. The installation of the lining carpet starts from the bottom of the roof slope and gradually moves up to the ridge. The width of the overlaps in the longitudinal direction must be 10 cm. The exception is organic backing materials (eg BiCARD). For them, when laying on a roof slope with a slope of up to 30 °, the width of the overlaps should be 60 cm, and if the slope is more than 30 ° - 10 cm. The overlaps of the sheets in the transverse direction are made 15 cm wide.
The lining carpet is fixed with wide-head galvanized nails, the nails are hammered at a distance of 20-25 cm from each other. Places of overlaps to a width of 8-10 cm are smeared with TechnoNICOL No. 23 mastic.
Note. When assembling with the "Accord", "Sonata", "Trio", "Beaver tail" cutting forms, it is allowed to mount the lining material only in places where leaks are most likely. It is laid in strips 50 cm wide along the perimeter of the roof (and along the cornice overhangs up to 60 cm above the plane of the inner surface of the walls, see Fig.), 1 m wide in the valleys, 50 cm along the perimeter of the roof windows and 1x1 m around the passage elements. The terms and conditions of the warranty are subject to change and become the same as for products from other manufacturers. The climate in different regions of Russia differs significantly, so this note does not apply to all regions, but only to the Central Federal District, the Southern Federal District, the Volga Federal District, the Northwestern Federal District and the Northwestern Federal District.
4. Strengthening the gable overhangs
To strengthen the gable overhangs, metal end strips are used. They are fixed over the lining material with roofing nails in increments of 12-15 cm, the nails are hammered in a checkerboard pattern. The end planks are overlapped, the width of the overlaps should be 3-5 cm, in these places the nails are hammered in after 2-3 cm.
5. Preparing the valley
There are two ways of installing Shinglas soft roof in valleys - open and "undercut" method. The preparation of the valley depends on which method will be used.
Along the axis of the valley (1), a TechnoNICOL valley carpet (3) is laid over the self-adhesive lining material (2) with a horizontal offset of 2-3 cm. On the underside, the valley carpet along the perimeter 10 cm from the edge is smeared with TechnoNICOL bituminous mastic. When using the open method of arranging the valley, the valley carpet can be replaced with a metal strip with an anti-corrosion coating. This replacement is appropriate for regions with a hot climate. The valley carpet (or metal strip) is fixed with roofing nails, they are hammered at a distance of 2-3 cm from the edge of the material in increments of 20-25 cm. It is desirable to lay a continuous (without overlap) valley carpet along the entire length of the valley. If this is not possible, parts of the carpet are overlapped. Overlaps are made 30 cm wide, the material in these places must be carefully glued.
Undercut method
When constructing a valley using the "undercutting" method, it is not necessary to mount the valley carpet.
6. Marking the roof slope
The markings are guide lines that, when laying soft tiles, help align it vertically and horizontally. This is especially true in the case of irregular geometry of the roof slope and the presence of any structures embedded in the roof. Vertical lines are applied in increments equal to the shingle width of an ordinary tile. 5 rows of material should be placed between the horizontal lines, so they are applied approximately 80 cm apart. It should be remembered that the marking performs only a guiding function, and is not a guideline for fixing the bituminous roof.
Prior to installation, shingles from several packages are mixed or sheets are taken from them one by one.
If Shinglas is to be laid at a low temperature (below +5°C), the packages must be placed in a warm room (+20°C) for at least a day in advance. From there, several packages are served immediately before starting work. The self-adhesive strip on the tiles should be heated with a thermal (construction) hair dryer.
When working on a roof, the material should be cut on an underlay board so as not to damage the underlying roofing.
In sunny and hot weather, you should not walk on the laid roofing, as marks and stains may remain on it. You need to move along the roof through special manholes.
2. Rules for fixing ordinary tiles
Each tile shingle is fixed to the base with wide-head galvanized nails. The number of fasteners depends on the angle of inclination of the roof slope. With a slope of up to 45 °, each shingle is nailed with four nails, more than 45 ° - with six nails. Nails should be placed evenly and hammered in so that the caps do not cut into the surface of the soft roof, but are in the same plane with it (see Fig.).
The location of the fasteners for all forms of Shinglas cutting is shown in the figure. On both sides, the shingles are nailed at a distance of 2-3 cm from the edge.
3. Starting strip
For the starting strip, universal ridge-cornice shingles or shingles of ordinary soft shingles with cut petals are used.
Ridge-cornice shingles are used as a starting strip when laying Shinglas with the "Accord" and "Sonata" cutting shapes. It is laid on top of the cornice strips 1-2 cm above their inflection (see Fig.). The width of the indent from the bend of the cornice strips depends on the angle of the slope and the length of the roof slope. The longer and steeper the slope, the wider the indent should be.
When installing flexible shingles Shinglas with cutting forms "Beaver tail", "Trio", "Accord", "Sonata" shingles with cut petals are used for the starting strip. Before laying, their lower side in places where there is no adhesive layer should be smeared with TechnoNIKOL mastic. Patterns from ordinary tiles are mounted in the same way as ridge-eaves tiles.
The starting strip for sheets with the cut shape "Dragon's tooth" is made from shingles of an ordinary tile, it is not necessary to cut them. Their laying is carried out similarly to ridge-eaves tiles.
4. Laying the first, second and subsequent rows of tiles
On long roof slopes, it is recommended to start laying the material from the middle of the slope, this will facilitate its horizontal leveling. 1-2 cm recede from the initial (central) strip and the first shingle is mounted (see Fig.). At the same time, attention should be paid to the fact that the junction of the shingles of the first row of tiles does not coincide with the junction of the elements of the starting strip.
Mounting must be done with diagonal stripes (see fig.).
Depending on the shape of the cut, the laying of soft roofing can be carried out in diagonal stripes, in the form of a pyramid or a vertical strip (see pictures). The shingles of the second row begin to be laid from the middle of the slope, with a horizontal offset in any direction by half a petal relative to the tiles of the first row. In this case, the lower edge of the petals of the tiles of the second row should be located at the level of the upper edge of the cutouts on the shingles of the first row.
Sheets of the third row are mounted with an offset of half a petal relative to the shingles of the second row in the same direction as when laying the previous row.
It is recommended to smear the extreme shingles of ordinary tiles in places where there is no adhesive layer with TechnoNICOL bituminous mastic to a width of 10 cm from the edge of the roof. Their upper corners are cut off by 2-3 cm for more efficient water rebound.
Note: stacked with an offset relative to the previous row by 15-85 cm. In this case, there is no need to adhere to a special order, the overall pattern should turn out to be abstract (see fig.).
In the region of the valley, ordinary tiles are mounted on top of the valley carpet on two roof slopes (see Fig.). Each shingle suitable for the valley is additionally fixed in the upper part with roofing nails (2) at a distance of at least 30 cm from the axis of the valley (1). Then, with the help of laces, two lines are beaten off (3). Ordinary tiles are cut along these lines, having previously placed a plank under it so as not to damage the valley carpet. The upper corners of the shingles suitable for the line 3 are cut to break the water (4). On the underside, in places where there is no adhesive layer, the bituminous roof is smeared 10 cm from the undercut line with TechnoNICOL mastic (5).
The width of the valley gutter depends on the location of the building and the size of the watercourse from the roof slopes, it can be from 5 to 15 cm. If the building is located among trees (for example, in a forest), then the gutter is made wider to facilitate the removal of leaves. With a significantly different watercourse from the slopes, in order to prevent the roofing material from being washed away with water, the gutters of the valley are shifted towards a smaller watercourse.
Undercut method
When constructing a valley using the "cutting" method, first the level shingles are laid on a slope, which has a smaller slope angle (see Fig.). In this case, sheets of ordinary tiles should go onto a steeper slope by at least 30 cm. In the upper part, each shingle is additionally fixed with roofing nails (2) at a distance of at least 30 cm from the axis of the valley (1). When the slope with a smaller slope is completely covered, the tiles are laid on the second slope. On a steeper roofing slope, at a distance of 7-8 cm from the axis of the valley, a line (3) is beaten off. Sheets are cut along this line, suitable for the valley from a steeper slope (it is recommended to fit a plank under it so as not to damage the underlying material). The upper corners of the extreme shingles are cut to rebound water (4). On the underside, in places where there is no adhesive layer, these shingles are smeared to a width of 10 cm with TechnoNICOL bituminous mastic (5).
6. Arrangement of ribs for skates and skates
Method #1
When applying this method, ridge-cornice tiles are used. Previously, it is divided into three parts by perforation. Ridge-cornice tiles are used for the installation of "Accord", "Sonata", "Dragon's tooth".
Edge. The shingles facing the edge are cut so that a gap of 0.5 cm wide remains between the tiles from adjacent slopes. Two reference lines are beaten off along the edge with the help of laces. Lay flexible tiles on the edge in the direction from the bottom up. The elements are mounted with an overlap, the overlaps should be 3-5 cm wide. Euromet recommends fixing each shingle with four nails (2 on each side) so that the top one covers the fasteners of the underlying one.
Skate. Soft roofing on the ridge begins to be laid from the side opposite to the direction of the prevailing winds in the area. Its installation is carried out similarly to the installation of tiles on the edges of the roof.
Method #2
When using shinglas shingles with Trio, Sonata, Dragon Tooth, Beaver Tail shingles, the elements to cover the ridge and ribs can be cut from the shingles of ordinary shingles. For the "Sonata" cutting form, its upper part will be visible, and its lower part will be closed (see fig.)
On the underside, in places where there is no adhesive layer, the elements are smeared with TechnoNICOL mastic before laying. Shelter of ridges and ribs with patterns from ordinary tiles is carried out in the same way as with ridge-cornice tiles.
Important: When installing the Shinglas soft roof of the "", "", "", "" series at low (up to + 5 ° C) temperatures, it is recommended to bend the elements on a warm pipe with a diameter of about 10 cm. This will prevent them from cracking.
7. Installation of shingles SHINGLAS on curved surfaces (domes, cones)
On roofs of non-standard shape, Shinglas shingles can be laid in two ways - segmental and seamless. When using any of them, the underlayment must first be laid.
Mounting Shinglas on a domed or conical surface in a segmental way involves dividing it into segments. The size of the segments depends on the size and shape of the covered surface. The lines are beaten off with the help of laces. An ordinary tile is mounted on each segment, and ridge tiles are mounted on the joints between them (similar to a ridge and roof ribs). The width of the ridge tile must also correspond to the dimensions of the covered surface.
1) Metal tip (installed after mounting the shinglas);
2) vertical cutting lines (slope marking);
3) a whole petal of a tile;
4) 1/2 petal tiles;
5) ANDEREP lining carpet.
When laying tiles with a seamless method, special attention must be paid to the marking of the surface (see Fig.). First, on its base, marks are made with chalk in increments equal to half the petal of the tile used. From these marks on the lining carpet (5), lines are drawn to the top of the covered surface (the lines are connected at the top). Ordinary tiles are cut into separate petals, of which the first row is mounted. The next row is shifted by half a petal relative to the previous row. The material for it is cut in accordance with the applied marking lines (2). When the width of the trimmed elements becomes half the original (4), whole tile petals (3) begin to be used again for the next row. In this order, the roof is laid to the top of the surface. The top is decorated with a metal tip (1).
8. Connection device
For a smoother bending of materials, a triangular-shaped rail is nailed to the roof slope at the junction of the wall (see Fig.). It can be made from a diagonally cut wooden beam with a section of 50x50 mm or use an ordinary wooden plinth. If the wall adjacent to the roof is brick, it is pre-plastered and primed. Shingles of an ordinary tile suitable for adjoining lead to a nailed lath. Strips of at least 50 cm wide are cut out from the TechnoNIKOL valley carpet. On the underside, they are treated with TechnoNIKOL bituminous mastic over the entire surface and laid on top of the tiles. The strips of the valley carpet are positioned so that they go onto the wall by at least 30 cm (and even higher in regions with heavy snow loads). The upper edge of the adjoining material is inserted into the groove and pressed with a metal apron. The structure is fixed mechanically and sealed with polyurethane, thiokol or silicone sealant.
The method of sealing the joints of the roofing with ventilation pipes and chimneys is shown in the figure. Patterns are made from a valley carpet or a metal sheet with an anti-corrosion coating, they are cut and bent in the indicated places. First, the front pattern is mounted on top of the shingles of ordinary tiles suitable for the pipe. Then lay the side and lastly the back patterns. They are brought under the shingles of the material. From the back and sides make a gutter 80 mm wide. At the shingles of the soft roof suitable for the pipe, the upper corners are cut to repel water. The underside of these shingles in places where there is no adhesive layer to a width of 10 cm is smeared with TechnoNICOL bituminous mastic.
If the pipe section is more than 50x50 cm, and it is located across the roof slope, a groove is made behind the pipe (see Fig.). This will prevent excessive accumulation of snow behind the pipe.
If the bottom of the roof slope is adjacent to the wall, a metal storm drain is mounted at the end of it (see Fig.).
9. Pass-through elements
For sealing the places where communication pipes, antennas, etc. pass through the roof. use special passage elements (see fig.). The passage element is fixed mechanically (with nail joints). Shingles of an ordinary bitm tile are laid on it, cut off and fixed to the flange with TechnoNICOL No. 23 FIXER mastic. Then a suitable roof outlet is installed on the passage element.
TechnoNIKOL roof ventilation elements are non-insulated and insulated (see fig.). They are part of the ventilation and sewerage systems. The use of polyurethane-insulated ventilation outlets is advisable in areas with long, frosty winters, since condensate does not freeze inside them. It is not recommended to install caps on sewer roof outlets, as condensate accumulates in them. If it freezes, it will interfere with normal ventilation.
For a more aesthetic appearance of the roof outlet, a cap without internal cuts can be installed on it (see Fig.). In addition to its decorative function, it helps prevent precipitation and foliage from entering the pipe.
Roof care
- In spring and autumn, it is necessary to inspect the roof to check its condition and timely detection of defects.
- It is recommended to remove leaves and small debris from the roofing with a brush with soft bristles. Do not use sharp tools as this may damage the tiles.
- Items with sharp edges are removed from the roof by hand.
- Drains, gutters and pipes should be checked periodically and cleared of debris as necessary.
- If a large amount of snow accumulates on the roof, it is removed in layers with a non-sharp shovel. At the same time, a layer of snow about 10 cm thick is left to protect the roofing.
- From time to time, Euromet specialists recommend checking the condition (and, if necessary, repairing) metal parts, mounting holes, openings and other elements on the roof.
Shinglas shingle roof repair
Bituminous tile SHINGLAS is a repairable roofing material. If there are minor defects in the roofing, its local repair can be carried out independently. In this case, it is important to identify and, if possible, eliminate the causes of damage to the material. These can be, for example, installation errors, scuffs from closely spaced tree branches, the presence of depressions in which water stagnates, etc.
Repair procedure:
- Elimination of the cause of damage to the roofing.
- Dismantling of damaged material.
- Laying new roofing material. The joints of the new soft with the main coating are heated with a thermal (construction) hair dryer.

Of course, no owner will refuse to have a reliable and at the same time quite affordable roof on his house. A well-planned hand-made installation will not only protect all structures from bad weather and possible damage, but also save a significant amount of financial resources. So, all of these qualities are possessed by an innovative soft roof made of flexible tiles, the basis of which is bitumen. Therefore, it is important to figure out how to properly install the roof of shingles.
It is necessary to study in detail how the flexible tile is laid, the installation technology of which has some peculiarities. Only strict observance at each stage of its laying will allow you to create a reliable and durable roof. It is about the technical characteristics of soft tiles, as well as the method of its installation, that will be discussed further.
What is a flexible tile made of?
Roofing made from this material has some other names, such as, for example, shingles, shingles or roofing tiles. The main advantages of such a roof are its low weight (the mass of one sheet is an average of 8 kilograms) and not too high a cost compared to a metal tile. Thanks to the first indicator, the construction of the house is not so massive, which allows you to save on building materials and wages, and the second characteristic allows the roof to seriously compete with other, heavier roofing types.
The basis of such tiles is usually fiberglass or fiberglass (less often - organic cellulose), impregnated with bitumen. These materials perform the functions of the so-called reinforcement, which holds together two layers of the SBS modifier, which directly affects the flexibility and elasticity of the coating. Outside, the material is sprinkled with slate, mineral chips and basalt granulate. They are able not only to protect the material from damage, but also to give it a variety of shades of color.
Tiling preparation work
The basis for soft tiles is chipboard, moisture-resistant plywood or boards. When choosing boards, you need to carefully select high-quality material. The best option would be to use a planed tongue and groove board. If its thickness is 2 centimeters, then the rafter pitch should be 6 meters. With a thickness of 2.5 - 3 centimeters, the step can be 1.2 meters. The minimum thickness of plywood is a distance of 1.2 centimeters (rafter step - 6 meters), with a thickness of 2 centimeters, the rafter step is 1.2 meters. One way or another, the butt points of the material must correspond to the rafter legs. When working with material such as flexible tiles, it is recommended to treat the installation of the base for it with an antiseptic. It is important that the boards used during laying must be dry. The base coat should be hard and even.
In addition to the coating itself and the material for the base, during installation, the following elements cannot be dispensed with:
- underlayment carpet, which can be represented by any bituminous rolled material, provided that the shingle roof is new. For an old roof, roofing material already in use can also be used;
- valley carpet, the role of which is played by bituminous material with the use of polymers, which is necessary to protect against moisture adjunctions to walls and ventilation pipes.
When laying the carpet, you must use the following materials:
- roofing sealant or mastic;
- building hot air gun;
- knife for cutting material;
- three types of nails: ordinary, roofing and galvanized;
- building strips required for processing adjoining, cornice and front.
When all the parts have already been assembled and the installation of flexible tiles is being carried out, the instruction requires the following set of rules to be observed during operation:
- Initially, a vapor barrier film must be fixed on the inside of the roof. The material is attached to the rafter legs with nails, and to the ends - with wooden planks. Film strips are connected with adhesive tape.
- After that, already from the outside, you need to lay a heater, for fixing which it is customary to use wooden bars.
- A film is laid on the insulation that protects the roof from the wind. For its fasteners, a counter-beam is used, to which it will be necessary to nail the crate.
- After that, boards, chipboard or plywood are laid. Fix the material with nails equipped with a wide hat, or self-tapping screws.
Laying shingles
When arranging a roof with soft tiles, one should first of all start from temperature conditions, since the structure of the material requires a special approach. Only high temperature, sun and the absence of any precipitation will ensure the greatest strength of the connection of the shingle elements to each other, and installation of flexible tiles in winter is not recommended, since this may lead to falling off a little earlier glued tiles (read: ""). Sometimes in cold weather it is allowed to use a hot air gun to heat the sheets of the coating. You can also heat the adjacent attic (attic) space.
- Initially, the arrangement of the lining carpet is carried out. It must be spread and nailed along the following sections of the roof:- cornice;
- ;
- valleys;
- skate;
- places of fracture of the roofing slope.
Provided that the slope of the roof is more than 20 degrees, the lining carpet should cover the entire roof area. You need to start work from the bottom, and relative to the crate, the carpet should have a perpendicular arrangement. It is nailed with an overlap (width - 15 centimeters) with a fixing step of 20 centimeters. It is important that each of the joints be carefully treated with bituminous mastic or special roofing sealant. A cornice strip is nailed onto the spread carpet, designed to protect the crate from moisture. If it is not possible to do this, then the cornice strip is simply wrapped under the crate base. They nail it with galvanized nails in increments of 5 centimeters.
- Then work is carried out on the device of the pediment. It is also necessary to nail end strips to it, which are designed to provide protection to the wooden crate and remove moisture down from the ridge. After their installation, you can proceed with the installation of ridge-cornice strips of the coating, which can be represented simply by soft tiles with cut off extreme parts. They are nailed joint to joint, retreating from the edge of 2.5 centimeters. These areas are recommended to be treated with bitumen-based mastic, with the help of which free edges are also attached. At this stage of work, it is also worth fixing the drainage elements - brackets that are used under the gutter.
- Flexible roof installation which differs in some features, requires the installation of a valley carpet. It must be laid on top of the main, that is, the second layer. This carpet should be located in junctions, recesses and other places that are optimally suited for the accumulation of excess moisture. It is fastened with galvanized nails in increments of 10 centimeters, and the edges are processed with bituminous mastic. If possible, it is better to use special glue - waterproof.
- It is after completing all these procedures that it is worth proceeding directly to. The material must be from different packages, since the sheets in them have a different shade. After installation work is completed, under the influence of the sun, the material will gradually acquire a uniform color. You need to start laying from the bottom of the central section of the slope. The adhesive part of the material must be removed from the protective film, and the coating should be pressed firmly to the base. From above it must be nailed with the help of 4 nails, stepping back from the ridge-cornice strip 4 - 5 centimeters. In this case, the petals of the material should completely cover the perforation of the strip located below. From the edges of the gable line, the coating should be cut to the required length and treated with mastic.
- An extremely important point is also the intersection with the chimney and ventilation systems. In this area, the lining carpet should be installed initially. The ventilation base should be treated with bituminous mastic. Next, you need to select one of the fragments of flexible tiles and make a hole in it corresponding to the ventilation device (read: ""). After finishing laying the coating, the base must be treated again with mastic.
More difficult is the work with the chimney. In the place of its contact with the roof, three triangular rails should be nailed, located at right angles to the pipe. Then a lining carpet is laid around the chimney, which is overlapped and processed with the same mastic (read also: "
Private construction and the use of soft roofing is a topic that is quite relevant. This material has many advantages. Among them are light weight, absolute tightness, visual appeal, the possibility of using a wide variety of roof shapes, a long useful life and the low cost of a soft roof. Moreover, the rain does not drum on such a roof, but quietly rustles. In addition to high operational and technical characteristics, the material allows you to install a soft roof on your own, without involving specialists.
The concept of soft roofing
The soft roof is a modern material, the base of which is fiberglass sheets impregnated on both sides with rubber bitumen. Rubber bitumen is characterized by high tightness and moisture resistance, which is why soft roofing has spread so much during the construction of buildings. Also, the soft roof in its composition has a special dressing that increases wear resistance and prevents the roll coating from sticking together.
Soft roofing is considered an ideal covering for roofs in which the angle of inclination is at least 11 degrees. Therefore, when choosing a material for such strict requirements, be careful. Soft roofing is often called shingles, which is used as the top layer of a roofing pie and differs from other materials in its structure, which resembles rolled materials.

A flexible roof can be laid by 1 person. The only requirement that we have already mentioned is put forward to the roof surface - a slope of no more than 11º. But the maximum slope angle is not limited. Laying a soft roof with your own hands requires the following materials and tools: a hammer, a knife, mastic, sealant, a mastic trowel, roofing nails, cornice and end strips, a waterproofing carpet, a ridge-cornice strip and work gloves.
Ventilation device
The ventilation system is able to provide air circulation, which is necessary to prevent condensation on the bottom of the base. Neglecting this stage when laying a soft roof on the roof will cause the truss system to begin to rot, and in winter ice and icicles will form.
The constituent elements of the roof ventilation system are ventilation ducts and outlets, gaps between the waterproofing and the base (at least 5 millimeters). Natural ventilation can be provided by ventilation holes that are distributed evenly under the eaves.
Lining layer
Cornice strips are made of metal and mounted on the overhangs of the cornices on the lining. They are required to protect the edges of the crate. Gable strips are also made of metal, they are fixed at the ends of the roof to protect the edge of the crate. The valley carpet provides additional protection of the roof from atmospheric precipitation. Choose it according to the color of the flexible tile.
In places where leaks are most likely, it is necessary to create a lining layer: on valleys, roof ends and eaves. A feature of the installation is the observance of the direction (from bottom to top) and overlap: in the longitudinal direction 150 millimeters, in the transverse direction - 100 millimeters. Places of overlap are usually coated with bituminous mastic.
Valleys and skates, respectively, are reinforced by 500 and 250 millimeters. At the same time, the valleys must be equipped with a lining layer on both sides, and along the ends and cornice overhangs it should be laid to a width of at least 400 millimeters.
The lining is nailed to the base with galvanized roofing nails every 200 millimeters. The lining carpet not only protects the roof from moisture, but also from destruction if the laying of the soft roof is suspended.
Preparatory work
The base to which you will attach the soft roof must be solid. It is in this that the process of constructing a roof made of soft tiles differs from roofs for which other materials are used. For example, a metal tile must be laid on a crate, in which a gap is allowed between the bars, which is explained by the high rigidity of the metal tile. A soft roof does not possess these qualities and therefore needs a preliminary installation of a solid foundation.
To equip the base, you can use oriented strand board, moisture-resistant plywood with a thickness of 9 millimeters or more, as well as grooved or edged boards. If you have chosen a board as a base, then it is recommended to preliminarily keep it in a pile until an equilibrium moisture level is reached.
Buy material in the winter and use it in the summer. The width of the boards is not more than 100 millimeters. It is desirable that the material has the same thickness and is sawn on a band saw. The maximum wood moisture content is 20%.
A video about the technology of laying a soft roof shows that such materials need to be laid with a shift of the seams - apart, while leaving a gap of 1 centimeter between them. The surface must be dry, clean and smooth. The quality of installation and the service life of a soft roof will depend on these conditions.
The roofing cake must necessarily have the following layers: a waterproofing layer laid on the rafters; mineral wool insulation, if you are planning an attic device; waterproofing roofing carpet, overlapped on the base from the outside.
The subtleties of installing a soft roof
To cover the roof with a soft roof with your own hands, in addition to having free time, you also need good weather. It is customary to carry out work in warm, dry weather, while the air temperature should not fall below plus 5 Celsius. If, due to necessity, it is necessary to lay a soft roof in the winter at the wrong time, the tiles must be kept in the building at room temperature before starting work. You can also use a hot air burner.
The choice of such a temperature regime is explained by the peculiarities of the shingle - a sheet consisting of 3-4 "tiles". It can be attached to the surface with nails or using a self-adhesive layer, which is located on the inside. The tightness of the tiles is ensured by the heat of the sun, under its influence, the sheets are soldered to the base and to each other. This does not happen at sub-zero temperatures, and high-quality insulation is not obtained.
Soft roof tiles should be used simultaneously from 5-6 packages and selected in turn one element at a time to avoid sharp differences in shades in case it is necessary to repair the soft roof with elements from another package. It is in this property that another advantage of this material lies: a small difference in shades facilitates the process of replacing tiles and decorates its matte surface.
The choice of mastic
For laying the top layer of a soft roof, a bitumen-polymer material should be used, which allows you to make a continuous elastic coating that can withstand thermal and mechanical deformations of the base. According to the technology of laying a soft roof, it is recommended to use cold and hot mastics for attaching rolled material to the roof.
Cold mastics are traditionally used for the inner layers of the roof, and the hot substance is used as an outer coating. Cold mastics include roofing material and bitumen, and hot mastics include tar and roofing felt. The mastic used must contain bitumen and a dust-like mixture or filler made from fiber. Among dusty materials, lime, gypsum and ash stand out.
Production of bituminous mastic
You can buy bituminous mastic, but you can also make your own. To do this, take the bitumen, which is close to 80% of the mastic, and filler. Taking 2 servings of bitumen and diesel fuel for 1 serving of filler, you will get a cold mixture. Bitumen needs to be heated to 180 degrees while diesel fuel and filler are being prepared elsewhere. Both boilers can be mixed only after the water has evaporated in the bitumen.
To make hot mastic, you need to use a boiler. In it, the bitumen should be heated to 200 degrees, while it is necessary to slowly add the filler. It is important that during the procedure the temperature does not fall below 160 degrees.
To check the quality of the mastic, you need to lay it at an angle of 45 degrees, after heating the mastic to 60 degrees. The video on laying a soft roof shows: if the coating drains, then its quality is poor. If it does not drain, then you should let it dry. When drying, cracks will not appear in high-quality material.
Laying a soft roof
Before laying the roof directly, walk with a solution of bitumen and diesel fuel on a wood surface. Then slowly cover with mastic, then lay the glassine and roofing material. It is customary to start installation from the middle part of the cornice and move to the ends to the right and left. On the wrong side of the soft tile, before applying, you need to remove the film that protects the adhesive.
If you use cold mastic, then you need to wait 12 hours after applying the layer, only then you can apply a new layer. When covering with hot mastic, you can apply layers one by one. Each element of the roof must be nailed in the amount of 4-6 pieces.
When laying rolls according to the instructions for laying a soft roof, make a 7-10 cm overlap. In all cases, it is recommended to follow the overlay rule: position each top row so that the fastening joints of the previous one are closed. There is a displacement of the next new layer, depending on their number (with 2 layers - by half, and with 3 - by a third).
Cut off the excess along the edges of the roof and glue it with mastic. Due to the properties of modern soft roofing materials, the useful life of a roof covering is about 30 years. But this does not mean at all that you can forget about preventive measures.
Laying near ventilation pipes
Proper sealing of joints and careful fixing of material require space around antennas and pipes. The installation of a soft roof here is easy, provided that through elements are used. Without such components, the tightness of the coating is violated. Even before the shingles are laid, you need to outline the places where you will install ventilation and pipes.
Then you need to cut holes around which the edges of the lining carpet will be glued with mastic. Spread the upper surface of the carpet along the contours of the elements to be glued and nailed. Lay the tiles on top of the mastic.
It is recommended to treat the joints of the upper part of the passage element and bituminous tiles with a sealant. Having brought the work to the ridge line, you need to use special ridge elements of flexible tiles, which are bent over it, glued to the mastic and nailed.
Soft roof repair
The frequency of repairs that need to be carried out with the roof of the house depends directly on the base on which you installed the tiles, and on the cost of laying a soft roof. Timber lumber, cement and concrete screed - they all react differently to soft roofing, which causes some damage.
Cleaning up the damaged area
Immediately before starting the repair, determine whether such work is needed at all and to what extent. To do this, evaluate the degree of damage present. If holes have formed in the roll coating, it is recommended to fill them with mastic, observing the sequence of materials used for this.
Repair of rolled roofing should be carried out exclusively on a clean area. And this is very problematic, because there is a special dressing on the roofing material. For this reason, it is necessary to thoroughly clean the area where the repair work will be carried out.
The crumb can be removed by using process oil. Anthracene oil is best for cleaning roofing felts, and solar oil is used for roofing material. Clean with an ordinary cloth or brush. With this treatment, you can remove the topping and soften the surface for further repairs.
Repair work
After preparing the damaged area, you can proceed to the main work. With small defects, you can use the usual mastic with a patch. But this solution is not suitable if all roofing layers are broken.
If several layers of the roof are damaged at the same time, it is recommended to clean the area from the old layer of mastic and dirt, and then dry it. After that, it is necessary to prepare a mastic mixture with the addition of sawdust or sand. This mixture should putty all existing damage so as to even out the edges. Mastic on all sides of the patch should come out at least 10 centimeters.
With the help of hard brushes and brushes, the mastic can be applied to the most inaccessible places. If you are working on a small area, then it is advisable to use a simple spatula that allows you to apply thick mastic and a mass with sawdust. If a “water bubble” occurs in the roof, repairs must be carried out in the same way as in the situation with a conventional hole. The main thing is to determine in time the source where the water comes from.
If cracks appear in the roofing material, it should be cut to the bottom layer. Then clean up excess mastic and debris, after which the area is dried and filled with new mastic. You can do without an incision if the cracks are small. They should be closed with a patch and mastic. If small cracks appear throughout the area of the soft roof, then it must be prepared and covered with heated mastic.
Powder recovery
After repairing the soft roof, it is necessary to renew the removed layer of dressing in place in order to avoid excessive heating of the material and melting of the mastic. To do this, smooth the surface and cover the roof with sand. Excess topping, which does not stick to the roof, will eventually be removed by itself. However, if you want, you can remove it yourself.
Now you have learned what advantages a soft roof has - tightness, long service life and a reasonable price for laying a soft roof. Follow our instructions carefully to install the shingles correctly. Use the recommendations on the choice of mastic and its preparation. And if minor problems arose during the operation of the roof, re-read the information about repairing a soft roof again.
Installation of bituminous tiles can be done in several ways. For example, a single-layer tile can be mounted both from the bottom up and from the top down. On slopes with pincer-shaped elements (cuckoos), a combined installation is carried out, that is, first, on one side of the cuckoo, they raise the roof to the level of the cuckoo ridge, then they mount a row over the entire slope above the cuckoo and after that they lower the cuckoo on the other side, and the upper part of the slope ( above the cuckoo) are raised with tiles already along the entire length of the slope.
A two-layer flexible tile is mounted only from the bottom up (from the eaves to the ridge).
Installation of flexible tiles
Stages of roof installation
The whole process of roofing from bituminous tiles can be divided into the following stages:
Installation of the starting row
Eaves tile (shingles) - a tile of a rectangular shape. It is the first (starting) row for the entire roof. Cornice tiles are calculated separately and go directly to the color of the selected roof.
To calculate the number of eaves tiles, take the total length of all roof eaves. The unit of measure for cornices is a running meter. Can be used instead of cornice tiles ordinary tiles. At the same time, the petals from ordinary tiles are cut off with the help of giving the most ordinary shingle of the tile a rectangular shape.
Mount the starting tiles according to the pre-installed ones.
self-adhesive cornice tiles mounted along the entire cornice overhang, having previously removed the protective film from the self-adhesive base on the underside of the tile. The shingles of the cornice tiles are laid close - end to end to one another, retreating from the edge of the drip 5 - 15 mm. The cornice shingle is nailed near the perforation points, followed by overlapping of the ordinary tile fastening points.
Installation of an ordinary bituminous tile
Bituminous tiles are laid after having previously cleaned the protective film from the self-adhesive base.
Laying of flexible tiles - ordinary shingles lead from the center of the ramp. They usually start from the eaves. On the cornice, the first row is laid so that its lower edge is located no more than 1 cm from the lower edge of the cornice tiles, and the petals of ordinary tiles cover the joints of the cornice tiles.
Each tile shingle is nailed with four large heads.
On the end parts of the roof (pediments), in the places of valleys and hips, the tiles are cut with a roofing knife along the edge. At the ends of the slopes, they are glued with a special bituminous mastic adhesive, which is applied with a spatula in a thin layer on a gable metal drip.
Roofs with valleys
If there is a valley on the roof, the sequence of work must be carried out in the following order:
- The first is always the installation of the lining carpet;
- Next, the pitched brackets of the gutters are mounted on the lining (if necessary), after which the droppers are installed;
- After that, in the valley they cover the valley carpet
- Roofing tiles are mounted on top of the valley carpet.
In the places of the valleys, the tiles are cut so that a groove 15 cm wide is formed in the valley. The edges of the tiles on the valley are raised and glued with bituminous glue using a spatula.
Installation of ridge tiles
For skates, the same tiles are used as for cornices. According to the perforation, the shingle of the cornice tile is divided into three pieces. Therefore, this tile is called Konkovo-Karniznaya or KNK for short.
Beforehand, the protective film is removed from the CNC from the underside of the tile.
The ridge is mounted from the side opposite to the preferential winds. The bituminous ridge is bent in half and mounted with a fold along the roof ridge.
Fastened with 4 nails (two nails on each side of the ridge). The overlap of the ridge tiles is done according to the level of the self-adhesive base.
The last tile is mounted according to the following rule:
A part without a self-adhesive base is cut off from the tile, then a part with an adhesive base is glued into place using bituminous glue, a building hair dryer or a propane torch. Roofing nails are not recommended when installing the last ridge tile.
The article contains information about the technology of roofing with bituminous tiles. The device of a roof made of soft tiles, the technology of laying bituminous shingles and the nuances of the installation process are disassembled.

Lathing for soft tiles
It is necessary to start with the analysis of the crate. Since bituminous tiles are flexible and thin material, lying on any plane exactly repeats all its forms. Therefore, the installation of a flexible roof is carried out only on a continuous crate, assembled either from boards, or from sheet or slab materials, for example, from moisture-resistant plywood or OSB.
The board lathing is laid on the roof truss system, leaving a gap of 1 cm between the boards. This is the so-called compensation gap in case of moisture and temperature expansion of lumber.
Plywood and OSB boards are laid on a sparse crate of boards 20-25 mm thick and 100 mm wide. The installation step of the boards depends on the size of the stacked sheets or slabs. For example, if plywood 125x125 mm is selected for a continuous crate, then the installation step of the crate elements should be within 70 cm. That is, the plywood sheet should lie on three boards, at least.
Solid plank sheathing Source krysha-expert.ru
And two important points:
a gap of 1 cm is left between the stacked plates or sheets;
the panels are laid with an offset of half the element, thus achieving a uniform distribution of loads on all sheets (plates).
Flexible tile installation technology
Like all construction processes, the laying of bituminous tiles is divided into two stages: preparation, and direct installation of roofing material.
On our website you can find contacts of construction companies that offer roofing services of any complexity. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".
Preparatory work
The first preparatory operation is the installation of a drip. This element, made of painted galvanized steel sheet, is a corner up to 3 m long. The width of each shelf varies between 15-25 cm. .
The dropper is attached to the crate with roofing nails, which are hammered into the upper shelf in a checkerboard pattern every 15 cm. Neighboring planks are overlapped with each other with an offset of at least 3 cm.
Installation of roofing (lining) carpet
First, what is a roofing carpet. This is a roll material from the category of bitumen-polymer. It is laid on the crate in order to:
Align minor defects of the lathing laid on the rafters.
Increase the waterproofing qualities of the roofing.
Prevent the formation of condensation on the wooden deck.
So, the technology of laying soft tiles on the roof begins with the installation of roofing material. First of all, it is laid in strips on valleys and cornices. But you need to start with the valleys. The lining material has a width of 1 m, so it is laid out so that it covers the slopes from the valley in two directions of 50 cm. At the same time, this type of material is self-adhesive, so the crate under it is not treated with adhesives.

On our website you can get acquainted with the most popular projects of houses in the decoration of which the ventilated facade technology was used - from construction companies presented at the exhibition of houses "Low-Rise Country".
Then lay the coating on the overhangs along the eaves. At the same time, the vertical hanging shelf of the dropper is half covered. Next, the remaining open area of \u200b\u200bthe roof slope is covered with rolled material. Here are a few nuances:
the strips of the roofing carpet are laid on the already laid ones (on the eaves and on the valley) so that the horizontal joints are overlapped by 10 cm, vertical by 15;
galvanized nails are hammered into each laid strip in places of overlap, that is, the fastener caps must remain under the edge of the adjacent strip, the fastener pitch is 20-25 cm;
the strips of the lining carpet, which cover the main part of the slope, are laid perpendicular to the eaves and the roof ridge, starting from the bottom, rolling the roll up;
each strip is fixed around the perimeter with nails;
to increase the sealing of the joints, the edges of the strips are coated with bituminous mastic.
Laying lining material on the roof slope Source eltctricon.ru
After the roofing carpet is completely laid, the gable strips are mounted. They close the edges of the laid material along the slope and will subsequently prevent moisture from penetrating under it. Installation of slats is carried out in exactly the same way as in the case of cornice elements.
Now it is necessary to strengthen the waterproofing qualities of the valley, because this element is subjected to the greatest loads from rain and melting snow. To do this, use a valley carpet - a roll-type material made on the basis of a rubber-bitumen composition reinforced with a polyester mesh. It is matched to the color of bituminous tiles.
It is simply laid out on a valley, glued to the lining carpet with bituminous mastic, which is applied under the edges of the material 10 cm wide. An additionally laid strip is punched along the edges with roofing nails. The step between the fasteners is 20-25 cm, the indent from the edges of the strip is 3 cm.
Installation of bituminous tiles
The preparatory stage of the installation of roofing tiles is completed. You can go directly to laying the roofing material itself. The first operation at this stage is the installation of the starting tiles.
In principle, where to start laying (from the middle of the eaves or from the edge), there is no difference. But experts recommend that with long cornices, installation should begin from the middle. Thus, it is easier to level the starting strip horizontally.
What is the start line. This is the same ordinary tile, in which the petals are cut off. Although many manufacturers produce a universal element that covers the roof eaves and its ridge.
Laying the starting strip is carried out along the eaves, stepping back from the edge of the overhang 1.5-2 cm. At the same time, it must necessarily cover the gable strips with its edges. This item is a self-adhesive material. But it must be pierced with roofing nails in the corners and along the perimeter every 20 cm, stepping back from the edges of the strip 2-3 cm. smeared with bituminous mastic.
Installation of the starting strip Source eltctricon.ru
Installation of ordinary tiles
The main requirement for laying the first row of soft tiles is an indent from the lower edge of the lining carpet, equal to 1 cm. An important requirement is the correct nailing of the material. The fastener should not cut into the roofing material, it should press it against the crate. Therefore, it is impossible to nail strongly or do it obliquely.
At the same time, each bituminous tile is nailed with four nails. The place of clogging is 2.5 cm from the upper edges of the petals. This is done so that the nail heads remain under the soft tile roofing element laid on top. If the angle of inclination of the roof slope is more than 45 °, then the roofing material is pierced with six nails.
Now, with regard to the layout of ordinary tiles. It all depends on the model of the material used. For example:
the Jazz model is laid regardless of the location of the petals;
model "Trio", "Sanata" are mounted with an offset of half the petal.
Laying and fastening ordinary tiles Source eltctricon.ru
Valley design
First of all, a valley zone is formed into which nails cannot be hammered. This distance is 30 cm in each direction from the axis of the valley. This is the most vulnerable place, where the accumulation of water is always large. Therefore, it is forbidden to make any holes in this area.
But the tiles themselves are laid, closing the valley area with a small gap of 5 cm. Only in areas where nails cannot be used, bituminous mastic is used. Therefore, these areas are treated with it, applying a width of 10 cm, and the tiles are laid.
Decoration of the pediment
Here the technology is the same:
installation is carried out so that a gap of 1 cm remains from the edge of the laid plank to the roofing material;
flexible tiles are glued to the base and the metal strip with mastic and at the same time fastened with nails.
Connection to the pipe
Chimney, ventilation pipes - elements that are necessarily present on the roofs. The most dangerous area is the junction of these pipes with the roofing material, so it must be hermetically sealed.
To do this, make a pattern of valley material or sheet iron coated with protective paint. But first, the walls of the pipes are closed around the perimeter with sheet metal, which is attached to the pipes with self-tapping screws. The height of such a plinth should be 30 cm.
A strip 50 cm wide is cut out of the valley carpet. It is laid near the pipes so that it covers the plinth (30 cm) and the laid bituminous tiles (20 cm). The method of fastening the strip is bituminous mastic.
An important point. First, the lower side of the pipe is closed in this way (meaning the lower side along the slope), then the two side ones go to the bottom, and at the end the top side goes to the side ones.
Next, the tiles themselves are laid, smearing the laid valley material with mastic. On the sides of the pipe, the tiles are laid so that it does not reach 8 cm from the pipe. It remains only to mount the metal strips, which are installed so that a visor is formed above the pipe walls. Therefore, the shape of the slats is Z-shaped. A strobe is laid on the pipe, where the upper shelf of the element is sunk. The strips are attached to the pipe itself with self-tapping screws. After that, the strobe joint is filled with silicone sealant.

Sealing roof penetrations
Small pipes, antennas create joints in the roofing pie through which water can penetrate under the roof structure. When constructing a roof from soft tiles, these passages must also be taken into account. For their sealing use special rubber caps. They are laid so that they go 2 cm onto the laid tiles with their lower edge. A mark is made on the lining carpet where it is necessary to cut a through hole for the passage.
Cut a hole with a jigsaw.
Bituminous mastic is applied on the reverse side of the cap.
The cap is placed in place.
Fix it with roofing nails, punching around the perimeter.
A layer of mastic is applied on top of the skirt of the cap.
Carry out the installation of soft tiles.
The junction of the roofing material and the cap is filled with sealant, which is sprinkled with stone powder on top.
Skate decoration
To cover the roof ridge, a universal element is used, which was used as a starting strip. It is simply cut into three parts, each part is laid along the ridge across, hanging the edges from each slope, and nailed to the crate with roofing nails. The cut parts are laid from bottom to top along the inclined edge of the ridge with an overlap of 3 cm. In order for the cut parts to bend well along the ridge, it is recommended to warm them up a little with a building hair dryer.

To ensure ventilation of the roof, special ridge elements are used, in the design of which there are slots or holes. Through the latter, there is an outflow of air from under the roof structure.
The ventilation element is installed along the ridge, fastened to the crate with nails, and then bituminous tiles are glued on top.

Conclusion on the topic
So, the roof of soft tiles is ready. No other operations are required. The main task of the manufacturer of works is to strictly follow the instructions that come with the roofing material. It is necessary to pay attention to the fact that there are certain additions or changes in the ongoing technology for each model of tiles. They are also marked in the instructions.
