Roof waterproofing. How to choose the material and do-it-yourself roof waterproofing

The roof is one of the important elements in the structure, which preserves the reliability of the entire building from the negative effects of precipitation. In order to extend the life of the roof, it is necessary to perform its waterproofing in a timely manner. It is desirable to carry out all work at the stage of construction of the building or at the time when it is being overhauled. Roof waterproofing is a complex set of measures that must be performed by highly qualified specialists.

Roof waterproofing cost (price per m2)

The cost of roof waterproofing depends primarily on the type of material and technology that will be used in the process of work. For example, rolled roof waterproofing is less labor-intensive, which means that the price of work will be lower.

Below is the cost of roof waterproofing, while the price for services is basic, the exact amount can only be given after the estimate is made, taking into account all the features of a particular design.

Roof waterproofing material cost

The quality of the materials used also affects the cost of waterproofing a flat roof. Currently, there are a large number of them, for metal tiles and other coatings, the price of which is presented in a wide price range:

The calculation of the material is carried out according to the manufacturer's recommendations, the average cost is indicated below.

Roof waterproofing - popular options at affordable prices

Consider the most popular types of materials for roof waterproofing.

1. Membranes. Repair of a soft membrane roof is one of the most expensive, but, nevertheless, in demand - after all, Moscow is known to everyone for its non-standard houses with original roofs. Namely, membrane waterproofing can be mounted on structures of various shapes and slopes. The advantages of the material include the speed of laying, a high rate of elasticity.

2. Coating waterproofing. Roof repair using bituminous mastics is one of the most affordable waterproofing options.

3. Roll materials. An old and time-tested method of waterproofing a roof will be an ideal option for metal roofing or for repairing a garage roof (the price will be low, but the quality will be excellent).

4. Injection isolation. This method is applicable in the case when it is necessary to waterproof hard-to-reach areas of the roof or if there are voids in the slabs.

5. Film. One of the cheapest and easiest methods of arranging roof waterproofing. Self-adhesive film is most often used under slate, metal tile or metal profile.

Roof waterproofing steps

The cost of roof waterproofing, as we have already found out, depends on the type of technology used, but the speed of the work is directly related to the material used. So, for example, to lay a waterproofing membrane, you need to perform the following steps:

Laying roll material involves pre-priming the surface with a bituminous primer.

The duration of the operation of the roof and its quality depend on the literacy of the work, therefore it is important to follow all the stages of laying or applying waterproofing material. Such complex works as roof waterproofing should be trusted to specialists, especially since the price we offer to our customers pleases with its democratic nature.

When erecting a new construction site or renovating an old building, it is necessary to pay close attention to the moisture insulation of the roof. It is she who, first of all, is at risk, since she takes on all atmospheric loads.

If the roof is not sufficiently protected from external precipitation and condensate, increased humidity will remain in the room, and this entails the formation of mold and fungus. Against the background of leaks, the interior decoration of the building will quickly become unusable.

All these problems can be avoided by carrying out high-quality waterproofing of the roof in time. It is especially important to protect a flat roof from moisture, which has almost no slope for water flow.

According to their design features, flat roofs are divided into:

• Cold (roofing lies on the frame without insulation);
• Ventilated (with grooves for moisture removal);
• Closed insulated (with insulation, but without ventilation holes in the base plates);
• Monolithic (from foam or aerated concrete blocks that do not need insulation);
• Inversion (structures in which there is a heater, protected from below by roofing material, and from above covered with screenings, turf, concrete and other materials);
• Operated (they can accommodate various infrastructure facilities such as sports grounds, courts, swimming pools).

For all varieties of flat roofs, a good solution is to arrange a drainage system consisting of gutters and catchment funnels.

It is also recommended to create the necessary slope during the installation process. This technological technique is carried out in several ways using inert materials, cement-sand mixtures, additional layers of insulation, specialized systems. The slope will solve the problem of water accumulation, however, the main protection of the roof lies in the insulation device.

Flat roof waterproofing methods

When choosing waterproofing, you need to proceed from the design of the floor, the intended purpose of the roof, its area and other factors. To date, the most popular insulating materials are:

Pasting the roof with a built-up coating is a long-known, traditional way of protecting against water. The main component that provides adhesion to the insulated surface is bitumen. The process of applying the material is accompanied by heating the contact surface to the melting point, which explains its name.

Until recently, roofing material was the most popular material among the welded materials, but due to the short service life and a large number of shortcomings, it is currently used less frequently.

Among modern materials, free from most of the shortcomings and providing better waterproofing, we can note:

To create a reliable waterproofing layer, knowledge of modern types of materials is not enough. Even one of them that costs more may be ineffective if the laying technology is violated.

Before starting work, it is important to understand that the main disadvantages of any welded roll material are the presence of seams, a low coefficient of stretching and not one hundred percent adhesion to the surface to be treated.

When laying built-up waterproofing, it is important to follow these recommendations:

• prepare the surface with high quality, clean it from dust, oil and treat it with a bituminous primer for better adhesion;
• lay the material sheets in several layers with the location of each subsequent layer above the joints of the previous one;
• maintain the optimum heating temperature of the bituminous base. Insufficient heating is the main cause of poor adhesion, overheating leads to burnout of the insulating sheet;
• carry out the deposition of the material on a completely dry surface, otherwise corrosion processes may continue under the waterproofing layer;
• take into account the rate and percentage of shrinkage of the structure when using welded waterproofing;
• carry out insulation work at a positive temperature, in view of the fragility of the frozen material of this type.

This material is advisable to use for roofs of complex construction: multilayer, insulated, with a hidden drainage system or operated, where great importance is attached to environmental and fire safety.

It is recommended to use it when insulating the roof with fibrous or inert materials (such as expanded clay), reinforced with concrete screed. The emulsion is sprayed either before or after the insulation, insulating it with a film coating.

Liquid rubber is an elastic mixture of latex and bitumen, which is applied to the surface by cold spraying and creates a durable homogeneous membrane. It reliably protects the roof from leaks at temperatures from -50°C to +80°C, without requiring restoration.

The cover adheres tightly to the base and does not let moisture in. The material provides maximum moisture protection of the internal space and is currently considered the most popular. The only downside is its high cost. At the same time, waterproofing with liquid rubber lasts up to 50 years and, of course, pays for itself.

Usage example: TN-ROOF Light system for a non-operated roof without thermal insulation on a concrete base.

Installation conditions: when installing a new and reconstructing an old roof without insulation, when installing a cold attic, during a major overhaul of the roof with the replacement of all layers of insulation.

Algorithm:

2. Technoelast EKP, STO 72746455-3.1.11-2015
3. Reinforced cement-sand screed with a thickness of at least 50 mm

Advantages:

According to the conclusion of the FGBU VNIIPO EMERCOM of Russia, the roof structure has a fire hazard class of K0 (45) and, depending on the parameters of the reinforced concrete slab, the fire resistance limit is REI 30 - REI 90, which allows the system to be used as coatings in buildings and structures of any degree of fire resistance and with any class of constructive fire hazard.

Regardless of the brand of material, the process of installing liquid waterproofing looks like this:

• The surface to be insulated is cleaned of debris, degreased and dried with a propane burner;
• If there are chips and cracks in the monolith, they are sealed with concrete mortar, and the protruding elements and reinforcement are removed;
• Using pneumatic equipment, liquid rubber is sprayed with a layer of 3-4 mm, starting from the corner. First of all, seams, areas with elevation changes, as well as brick or concrete fences along the perimeter of the roof are processed. Any protruding elements (rain outlets, chimney and ventilation pipes, fasteners) are covered with a sealed film and treated with liquid rubber 15 cm above the roof surface. After spraying the waterproofing, the excess film is cut along the contour and removed. The sections of transitions on the main surface of the roof are also treated with a spade up to 15 cm - this will help to avoid the formation of seams on the membrane.

Like liquid rubber, this type of waterproofing is characterized by durability, frost resistance and a high coefficient of elasticity. For a roof of a large area, this will be the best solution, since the membrane is available in rolls of solid width.

With this material, you can economically cover the roof of any configuration, minimizing the number of seams. PVC membrane is ideal for a simple flat roof with a slight slope - it is this design that is most popular today, because it is cheaper than a pitched one and provides additional space for organizing utility and infrastructure facilities.

The undeniable advantages of membranes include:

• simplicity and efficiency of installation;
• light weight rolls;
• environmental safety, the presence of a fire certificate.

The peculiarity of laying is that this rolled material does not need to be completely glued to the surface, like rolled welded insulation. Membrane sheets are lined with rows with a slight overlap, and the joints are heated by a burner and reliably soldered.

Usage example: built-up waterproofing of the operated roof for pedestrian loading.

Installation conditions: for the efficient and aesthetic use of the roof as an additional resting place, during major repairs or reconstruction with the replacement of all layers of insulation.

Advantages:

This solution contains all the best latest materials and technologies. The vapor barrier material Bipol EPP reliably protects the roofing pie from moisture. Heat-insulating extruded polystyrene foam T.N. Carbon Prof has ultimate compressive strength and low water absorption. The PLANTER geo profiled membrane not only helps to quickly remove moisture from under the coating, but also protects the waterproofing carpet from mechanical damage. A leveling layer of gravel laid with zero slope ensures a comfortable stay on this type of roof.

In the TN-ROOF Standard Pavement system, it is also allowed to lay tiles on a layer of gravel using a cement-sand mortar or a dry cement-sand mixture, and the finish coating can be paving slabs of any modification used in the improvement of residential areas and is characterized by high frost resistance and durability to foot traffic.

The main purpose of roof waterproofing is to protect the internal space from adverse environmental factors. The quality of such work and the correct choice of waterproofing materials must be given due attention. In many ways, the durability of the roof will depend on this, allowing the homeowner to subsequently save the owner from the need for expensive roof repairs.

Today, there are several waterproofing materials for roofing, which differ in the method of application and can be used with various roof structures. These common types of waterproofing include:

Rolled waterproofing combines affordable cost, providing the roof of the house with the necessary protection against moisture, and is durable.

In addition to the well-known roofing material to all of us, you can use glass roofing material and euroroofing material. The advantages of this type of waterproofing include the following: durability of the coating; high reliability; affordable cost.

The disadvantages include the complexity of installing rolled waterproofing. It is necessary to lay ordinary roofing material on bituminous mastic. According to its technology, such work is vaguely reminiscent of pasting walls with wallpaper. When using euroroofing material, it is not necessary to pre-treat the base of the roof with mastic, which makes it possible to somewhat simplify repair and construction work. After laying, the material is heated by a gas burner, which makes it possible to glue the rolled insulation and subsequently eliminate the possibility of leakage.

A variety of mastics can be used with flat roofs that combine ease of use, efficiency, and affordability.

Currently available for sale various types of liquid roof waterproofing, the materials of which differ in their composition, characteristics and cost.

The benefits of mastics include the following:

• Ecological purity.
• No shrinkage.
• Resistance to aggressive environments.
• Monolithic waterproofing.

With a number of advantages, such liquid waterproofing still has one significant drawback, namely durability. Even the highest quality masks serve no more than 6 years, after which it is necessary to raise the roof and renew the waterproofing layer.

Film materials

Durable, inexpensive polyethylene films are often used today for roof waterproofing. The popularity of this insulator can be explained by the convenience of its installation and affordable cost.

The simplest variety is polyethylene film, the use of which will require the arrangement of a double ventilation layer in the roof. The joints of the film floors can be sealed with adhesive tape or special equipment can be used for this work, which reliably solder the material, ensuring that there are no leaks along the seam.

On sale you can find the latest generation of film waterproofing, which is durable and with sticky layer, which is attached to the base of the roof, which simplifies repair work. At the same time, we note that such modern film insulation has a high cost, which leads to a significant increase in the repair budget.

We can recommend economical homeowners to pay attention to waterproofing films with anti-condensation coating. Such a protective layer is located on the wrong side, allowing the material to accumulate moisture, preventing water from flowing down onto the insulation. The drops of water accumulated by the insulator gradually evaporate or roll down without getting inside the roof.

Diffuse waterproofers

Diffuse films and membranes are currently considered the most high-tech and modern insulator.

They are able to pass moisture from the inside of the roof, but at the same time don't let her get in from the outside, which protects the heat insulator used and the roof from possible leaks.

On sale you can find the following types of diffuse membranes:

• Pseudo-diffuse films that have a low degree of vapor permeability. Their advantages include affordable cost. This material is mainly used on cold roofs and attics.
• Diffuse membranes with normal vapor permeability. Membranes can be used for arranging an attic and a warm roof. The only place where diffuse membranes are not recommended is in dusty attics, where the porous coating can clog, which degrades the performance of the waterproofing.
• Super diffuse three-layer membranes are designed specifically for use in harsh environments, they are not afraid of significant temperature changes and retain their performance characteristics for a long time.

Material selection

It is from the correct choice of waterproofing material that the trouble-free and durable use of the roof will directly depend. That is why the issues of choice will need to be given due attention.

Of roll materials, it has proven itself best products of Russian factories. It combines excellent quality, affordable cost and durability. But the purchase of inexpensive Chinese waterproofing, which has flooded domestic markets in recent years, is recommended to be abandoned, since such materials do not differ in workmanship, in two or three years the roof will require complex and expensive repairs.

The best waterproofing and diffuse membranes are manufactured by the Finnish manufacturer Takaful, the Czech company Yutafol and the Russian TechnoNIKOL. Products from these manufacturers combines excellent waterproofing properties and affordable price. Of the modern breathing membranes, experts recommend the German Divorol and the Russian TechnoNIKOL.

Self waterproofing roof

In each case, the installation technology of waterproofing material will vary depending on its type and specific characteristics of the roof. It is necessary to follow the technology of working with each insulator, which will guarantee the quality of the waterproofing and the durability of the installed roof.

We use roll materials. The popularity of rolled waterproofing is largely due to the ease of working with it, its affordable cost and reliability. Laying material on the roof is carried out as follows:

Surface must be free of dust and dirt apply a primer, which is made from a mixture of bitumen and gasoline.

As soon as the applied primer dries, you can start gluing strips of roofing material. For material fixation bitumen is used. You can apply the mastic with a rag, a wide brush or a roller. You can melt the bitumen in a barrel over a fire and raise it to the roof in metal buckets.

The edges of the glued strips of roofing material must be additionally smeared with bitumen, after which, using a blowtorch, the seams should be carefully melted, achieving a high-quality connection.

Ruberoid on the roof laid in several layers, inexpensive material can be used from below, and high-quality and durable roofing material with sprinkling is laid on top. The top layer of waterproofing can be generously smeared with mastic and covered with coarse sand.

Coating method

Liquid bituminous materials are used exclusively on flat roofs. It is necessary to apply the melted mastic with a spray, roller or brush. The surface must first be cleaned of dirt, after which you can immediately start applying the material.

Are popular rubberized waterproofing mastics which are not difficult to work with. Liquid rubberized material must be poured onto the roof surface, after which, with a brush or a wide roller on a long handle, gently roll the insulation over the entire surface.

Can be used for coating coating high pressure sprayers, which are designed to work with liquid viscous materials. The use of such equipment makes it possible to apply a coating in one layer and significantly reduces the consumption of mastic for processing one square meter of roofing.

Use of diffuse membranes

Diffuse films are laid directly on top of the insulation, and a small ventilation gap is left in the upper part of the roof, the presence of which prevents the formation of condensate.

The fastening of the membrane, which is laid with a slight overlap, is carried out using construction stapler or galvanized nails. Additionally, you can use double-sided tape, which glue all the joints.

High-quality waterproofing of the roof will guarantee the durability of the repair, while problems with roof leaks will be completely solved. It is only necessary choose the right waterproofing material and, in full accordance with the technology, lay it on the roof.

The waterproofing layer is the most important part of the construction of the roofing pie. For roof waterproofing, various bitumen, bitumen-polymer materials, membranes, mastics are used. Below we consider the features of these materials, the specifics of their application and the principles of choice.

Types of waterproofing materials

Soft roll materials

This category includes various brands of roofing material. The material is made of roofing paper coated with a layer of bitumen. It is used on roofs with different slopes. Its main advantage is low cost. But the service life of rolled bituminous materials is small - about 5 years, depending on the brand. Other disadvantages of roofing material are that it is highly flammable, and the base of roofing paper is extremely fragile. Under the influence of ultraviolet rays, bitumen loses its elasticity and rapidly loses its waterproofing qualities, so the coating needs to be updated regularly. For the indicated reasons, roofing felt is less and less used in the repair or installation of the roof, replacing it with more modern waterproofing roofing materials.

Bitumen-polymer roll materials

This category includes roll waterproofing made of SBS- or APP-modified bitumen based on fiberglass, fiberglass or polyester. Such a coating is durable, easy to install by welding or mechanical fastening. Polymer additives give bitumen elasticity, increase its resistance to adverse environmental influences and increase the service life of waterproofing up to several tens of years. Pay attention to the structure of the roll roof in the photo.

Bitumen-polymer roll materials can be used for waterproofing the roof of buildings and structures for any purpose. They are presented in various price categories - from "economy" to "premium". The material can be laid on any non-combustible even base, including when reconstructing an old roof.

membranes

Roofing membranes are made of PVC-P with the addition of plasticizers. The material is resistant to UV radiation, does not lose plasticity in frost, is easy to install (without fusing), creating a reliable waterproofing coating, vapor permeable. Roofing membranes are more expensive than other waterproofing materials, but the higher price is offset by a long service life (up to 40 years). Are applied at repair and the device of a roof of inhabited, commercial, industrial objects.

Elastic continuous coating based on a two-component mixture. It is applied to the substrate by cold airless spraying. Liquid rubber has good adhesion, full moisture resistance, lasts up to 30 years, it can be used to insulate roof elements with complex relief. The main disadvantage of liquid rubber is the complex installation and the need to use specialized equipment. The waterproofing covering from rubber is not vapor-permeable.

Bitumen-polymer mastics

It is applied in several layers when repairing small sections of the roof, used as coating insulation, sealing joints, cracks, and junctions with them. Used as an additional waterproofing agent when installing the roof. As the main roof waterproofing, bitumen-polymer mastics are not used, since the coating does not form a continuous, stable waterproofing carpet.

Features of the choice of waterproofing material for the roof

To create a reliable waterproofing layer of a roofing pie, bitumen-polymer roll materials and waterproofing membranes are most often used. One of the world's leading manufacturers in this segment is ICOPAL. IKOPAL roll materials for roof waterproofing are produced in two versions: for single-layer and for two-layer roofing systems.

Materials for the top layer of a two-layer roofing system are indicated by the letter "B" in the marking (for example, IKOPAL-V), materials for the lower layer are indicated by the letter "H" (for example, IKOPAL-N).

• For waterproofing flat roofs and roofs with a small slope, it is recommended to use two-layer roofing systems. They create a reinforced moisture-proof layer of a flat roof.
• For waterproofing a pitched roof, repairing a flat roof, single-layer and two-layer solutions are suitable. Single-layer systems are more affordable from a financial point of view. They are also lighter than two-layer ones, which reduces the load on the supporting structure of the building.
• Both single-layer and two-layer systems can be used as a material for repairing an old roof, reinforcing joints.

Advantages of roll materials from SBS-modified bitumen from ICOPAL:

• The polyester base in IKOPAL bitumen-polymer roll materials is strong and elastic, the waterproofing carpet lasts over 25 years.
• ICOPAL's SBS-modified bitumen protection profile solutions optimize the installation process.
• Roll coating can be laid at any time of the year (in the absence of precipitation).
• Slate dressing on top of the canvas protects the waterproofing carpet from the harmful effects of ultraviolet radiation.

Roof membranes

Membranes are a new generation of roll materials for roof waterproofing. Their service life exceeds 30 years. ICOPAL produces MONARPLAN membranes for roof waterproofing, which consist of three layers: two layers of plasticized elastic polyvinyl chloride and fiberglass (or polyester) between them to give the material strength.

Advice. If you are using the membrane to repair an existing roof, please note that membrane roll materials cannot be laid directly on the old layer of bituminous waterproofing.

Advantages of MONARPLAN membranes from ICOPAL:

• They have a low level of water absorption.
• Form a stable homogeneous coating.
• They have vapor permeability, which prevents the accumulation of condensate drops in the roofing cake.
• Tear resistant.
• Lungs - about 2 kg per sq. m (depending on the brand of membrane coating), do not create an excessive load on the supporting structure.
• Installation can be carried out at any time of the year, without the use of an open flame.
• Resistant to UV rays, temperature extremes, mold and mildew.
• They have a wide range of applications, suitable for roofing, underground waterproofing.
• Repairable.

In the MONARPLAN line from ICOPAL there are several types of roofing membranes for waterproofing an operated and non-operated roof, a “green roof” device.

Recommended. To simplify the installation of the roofing membrane and create the most reliable waterproofing, including on difficult sections of the roof, additional materials from the MONARPLAN series will help: metal sheets for fastening, a membrane sheet for waterproofing junctions, lining to reinforce corners, etc.

Roof membrane waterproofing is a system for performing work on flat and pitched roofs, the slope of which is not more than 25 °.

The materials used for roof waterproofing must have good physical characteristics. To be elastic, moisture-proof, tear-resistant and have quality indicators of heat resistance.

Waterproofing work on flat roofs

A worn out or severely damaged top protective waterproofing layer becomes the main reason for the frequent, or different, or complete replacement of the entire roofing.

Only timely waterproofing work on the roof will make the roof durable, preventing rapid wear of hydromaterials.

Periodic waterproofing and sealing of roofing is a prerequisite for the repair of any type of building. These works are designed to protect the roof from moisture, precipitation, preventing it from collapsing before its useful life.

Fused waterproofing

Fused waterproofing is a special type of roofing work, in which the installation of roofing materials on the base is carried out by fusing them, using gas and solar burners.

Installation of a soft roof is carried out using materials on a bitumen or bitumen-polymer basis.

Roof waterproofing works are carried out in 3 stages:

• ground preparation;
• application and drying of the primer;
• fusing waterproofing.

Mechanical waterproofing

Mechanical waterproofing refers to the work on the installation of bituminous materials by mechanically fixing them to the base, using roofing hardware.

When installing a rolled ventilated roof in the under-roof space, air vapors never form and the heat-insulating layer does not deteriorate.

Membrane waterproofing

Membrane waterproofing is work performed using special equipment. PVC, EPDM or TPO membrane is used as the main material. The technology of membrane roofing is similar in complexity and is used in industrial construction on flat and pitched roofs with an area of ​​more than 5,000 sq.m.

The physical characteristics of polymer membranes allow the roof to breathe. The accumulated condensate comes out through the pores of the material itself.

Spray liquid waterproofing

Sprayed waterproofing is work on the uniform application of liquid polymer rubber to the base of a flat roof. The use of such materials makes it possible to increase the resistance of the roof to aggressive chemical environments, to natural influences and mechanical damage due to elasticity.

Proper selection of waterproofing materials

There are a huge number of roofing materials in the world that require specific installation and adherence to step-by-step work technology.

Roof waterproofing material must have characteristics such as strength, elasticity and hydrophobicity.

Our experts will help you determine the properties of the material and how to use it. Roofing is also carried out by professional craftsmen.

Do not forget that the durability of the roof of your building depends on the successful choice of material. It should be remembered that even a small mistake in the process of improper operation of the roof can lead to tangible problems over time. There is no universal waterproofing material for built-up roofing, which can be used in all occasions.

Waterproofing soft roll roof- a very complex and important process, since the life of the roof will greatly depend on how well the water drainage system is thought out.

The formation of dead zones can adversely affect the properties of the material. Each structure can be characterized by different types of moisture, but if we talk about the device of a flat roof, it is important to provide for the movement of precipitation and their rapid runoff.

Sophisticated system of internal and external weir

Rain, melt water should not exert hydrostatic pressure on the structure, only then it will be possible to safely talk about the quality laying of the soft roof and its service life.

The appearance of stagnant water areas on the roof adversely affects the quality of waterproofing roll materials. It is the stagnant zones that play a decisive role in the deformation of the roofing.

Waterproofing a drainage system is a very complex and important process in the production of roofing works, since the service life of the roofing
will greatly depend on how competently the internal drainage system is implemented. Only then it will be possible to safely talk about the high-quality installation of rolled materials and the durability of the roof.

Roof waterproofing for industrial buildings

As for new construction, when at the stage of erection of an industrial building it is necessary to perform high-quality work, but at the same time also reduce the cost.

By using cheaper materials, you can minimize costs, but you can immediately prepare for a major overhaul of the roof in 2-3 seasons. The best way out of this situation will be the development and implementation of a new, more practical and cost-effective roofing pie.

Roof waterproofing is a complex process that requires high professionalism, deep knowledge and extensive experience with roofs of various designs. In order to save your strength, money and avoid fatal errors that can lead to disruption of the entire structure, contact only specialists.
