The roof of the house protects it from the negative effects of any precipitation and tightness is one of its functional purposes. Roof waterproofing prevents moisture from entering the insulation and structural elements and prevent their destruction.

Not so long ago, roofing material was practically the only waterproofing material, but now there are a lot of waterproofing options: gluing, coating, painting, penetrating, fused, sprayed and modern films with membranes.

In this variety, you need to correctly choose the most effective waterproofing for each specific case.

Wrapping waterproofing

Gluing waterproofing is a traditional method that has been used for many decades using roofing material. Its advantages are low material cost and ease of installation.

For the device of gluing waterproofing, it is required to prepare the base well: it must be dry and even so as not to damage the roofing material. The surface is primed with bitumen and a waterproofing layer is applied to it.

Currently, roofing material has been replaced by more modern analogues with better technical characteristics, among which: glassine, stekloizol, brizol, glass roofing material, vinyl plastic, isoelast, isoflex, mostoplast and ordinary polyethylene.

When choosing waterproofing for the roof, you must familiarize yourself with the properties different materials and their technical characteristics. Here a brief description of only a few of them.

Materials (edit)

Glassine is a roll material obtained by impregnating special roofing cardboard with bitumen. It is inexpensive, but it does not last very long, so it is not economically profitable to use it to waterproof the roof of a new house, but for budget repair it will do just fine.

Stekloizol is also an inexpensive roll material with a service life of up to 10 years. It is based on a simple fiberglass or fiberglass or fiberglass with a bitumen-polymer layer, on top of glass insulation is sprinkled with granite chips.

Brizol is also sold in rolls and is often used in industrial construction. Its production involves: rubber, petroleum bitumen, and plasticizers and asbestos as additives. According to their technical parameters it is very similar to izol (also a waterproofing material), but it is more expensive and has higher performance characteristics.

Glass roofing material - produced by the method of double-sided application of bitumen-rubber or bitumen-polymer binder to fiberglass, and on one side it is sprinkled with fine-grained, flaky or coarse-grained dressing. Glass roofing material has good physical and mechanical properties and durability up to 30 years. This is a roll material.

Viniplast (unplasticized polyvinyl chloride) - sheet synthetic material very high quality. It is lightweight, durable, flame retardant, easy to process, used in a wide temperature range, durable (service life up to 50 years).

Isoelast is a roll material obtained by double-sided application of a bitumen-polymer composition to a polyester base. It happens with coarse or fine-grained dressing (one-sided or two-sided) or it has a plastic wrap on one or both sides. Operated for up to 30 years and used in all climatic zones.

Isoflex - is actively used not only for waterproofing the roof, but also for sound insulation. This is a dense foamed polyethylene, there are varieties with an additional metallized coating.

Mostoplast is a bitumen-polymer roll material with unique properties. It is designed for waterproofing very complex objects, including underground (garages, swimming pools, galleries ...). The material is waterproof, strong and durable - up to 25 years.

Coating waterproofing

The name is associated with technology - the surface is coated with a special compound. Bituminous mastic made on the basis of pure bitumen is the most affordable tool.

Bitumen, applied in layers, and having a thickness of even several centimeters, retains its properties for no more than 5-7 years, and then, having lost its elasticity, it begins to crumble and loses its tightness.

When arranging bituminous waterproofing remember that the roof is susceptible to low temperatures - the surface is covered with microcracks, which become more noticeable every year and eventually pieces of insulation begin to fall off.

Polymer coating waterproofing has increased elasticity, resistance to aggressive external environment and a long service life. But the consumption of this tool is greater than that of the bituminous analogue.

Bitumen-polymer compositions include bitumen, synthetic rubber and plasticizers that improve the elasticity of waterproofing. They are easy to use and do their job perfectly.

Lubricating waterproofing is considered not only bituminous and polymer mastics, but also silicone and polyurethane.

Hot or cold

Coating waterproofing according to the application technology can be hot or cold. The hot method involves heating the composition with its subsequent application to the surface. Prepared mastic should be used immediately.

The cold method does not require heating, and the waterproofing can be applied even intermittently - its properties do not change.

Roof coating waterproofing is usually used on flat roofs ah or on roofs with a minimum slope.

Painting waterproofing

This waterproofing is applied with a simple roller or spray gun to the surface to be insulated from moisture. Usually, two to four layers are made, observing the necessary intervals for hardening of each previous layer. Thickness paint waterproofing 3-6 mm. To impart increased strength to the surface, fine sand is scattered over it.

Paintable waterproofing is presented on construction market special emulsions, enamels, paints and varnishes.

The service life of this waterproofing is short (within five years), but it is inexpensive, therefore it is also in demand.

Penetrating waterproofing

Penetrating waterproofing can be called a new generation material. It not only covers the surface, preventing moisture from entering, but also penetrates about 20 cm inside it, strengthening the structure and filling even the smallest cracks.

Liquid glass, polymers or synthetic resins are used as penetrating waterproofing.

This waterproofing is especially effective when applied to porous surfaces and is mainly used on flat roofs.

The strength of concrete after processing with such a composition increases by twenty percent. Using deep penetration compounds, you can extend the duration of the waterproofing protection to 70 years or more, because it is very stable and does not react even to low temperatures.

Fused waterproofing

Fusion-bonded roof waterproofing is a roll material made on the basis of fiberglass, fiberglass or polyester with bitumen or polymer impregnation (binder). The thicker the material, the more durable it is (its service life is from 10 to 25 years).

The welded waterproofing is fixed to the base by melting its lower layer under the action of a gas burner. The bitumen is melted, the roll is rolled back, treated with fire again and rolled back and so on until the roll ends. The cured binder reliably bonds the waterproofing material to the roof surface.

Two-layer weld-on waterproofing is resistant to mechanical damage, easy to install and has a low price. It is widely used at industrial and civil construction sites, on exploited and unexploited roofs with a slope of no more than twelve degrees.

Sprayable waterproofing

Sprayable waterproofing is best suited for flat roofs with overhangs and parapets. It, with a layer of the same thickness, covers not only a flat surface, but also a complex relief, leaving no seams or unprotected areas, creating a one-piece sealed protection.

The most popular material that is sprayed on roofs is liquid rubber. It is applied using very expensive equipment (electric or gasoline) by airless spraying.

Adequate spray installations and quality liquid rubber are required to create reliable insulation. All this can only be provided by large specialized companies that train their specialists to work with new materials and the most modern equipment.

No room for error

Roof waterproofing is a very important stage in the construction of a building with any roof structure, but when installing a flat roof there is no right for even a minor mistake, because, unlike pitched roofs that have a finish coating, a flat roof is protected from precipitation and other environmental influences only by a layer of waterproofing ...

To extend the life of a flat roof, it is sometimes covered with a special dressing. On the operated roofs, a concrete screed is made and tiles are laid. The main thing is that in the process of installing the screeds, they do not damage the waterproofing.

Modern membranes

There are waterproofing materials that are mainly used on flat roofs, and there are those that are equally effective on both flat and pitched roofs - these are membranes. They are quickly assembled and do not require the use of expensive specialized equipment.

The easiest way to mount them on pitched roofs is mechanical. They are spread on the crate, starting from the bottom of the roof, so that an overlap of about 20 cm is obtained at the joints. The material is fixed on the crate with a construction stapler. A counter-lattice is stuffed on the laid waterproofing and roofing material is laid.

But do not confuse a vapor barrier film with a waterproofing membrane - they have different purposes. The film is designed to protect the insulation in the roofing cake from wet vapors, preventing them from penetrating from living quarters. Waterproofing not only protects against wind and moisture, but also due to the fact that it has a porous structure, it allows the moisture that somehow got into the roofing cake to evaporate.

Membranes are polymeric insulating materials... Roof waterproofing using membranes has proven itself well. The efficiency of the membranes is better, and the service life is longer, so they are in demand in the construction market.

Their types

Membranes can vary in width or length, in thickness and color, in structure. They are flexible but durable and are used on roofs with different slopes. There are three main types of membranes: EPDM, PVC, TPO.

EPDM - ethylene-propylene rubber - is made from artificial rubber and reinforced with a polymer mesh for strength. They have been produced for over 50 years and are still in demand due to their strength, good adhesion and durability.

PVC membranes are made from polyvinyl chloride with the addition of plasticizers for flexibility and have a reinforcing mesh for strength. Manufacturing companies are constantly improving their products, introducing new ingredients into their composition, so that it fully meets the needs of customers.

TPO membranes are one of the most modern, among those that have recently appeared on the domestic market. They were developed in the 1990s in America. The membranes are made of synthetic rubber and polypropylene and combine the properties of both plastic and rubber.

Today it is, perhaps, one of the most sealed waterproofing materials. It has a long lifespan, but the price is not the cheapest either. It is ideal for those homeowners looking to install and forget about roofing without having to do annual maintenance and repairs.

And for tiles, and for ondulin

Roof waterproofing must be reliable. And this quality directly depends on the correctly selected system for a specific roof covering. For example, metal tiles (seam roofing, metal slate) have a high thermal conductivity and, when the weather changes with a sharp temperature drop, condensation appears on the metal, therefore it is best to use membranes with an anti-condensate layer - fibrous and hygroscopic.

Ceramic or cement tiles, slate cannot create an airtight protection for the house, therefore, they must be waterproofed under the roof space. In this case, materials with good tightness will be appropriate.

Ondulin itself is quite sealed, and some manufacturers in the instructions for its installation even indicate that waterproofing may not be used, but still it is better not to neglect additional protection from precipitation, especially if attic floor insulated.

Roof waterproofing

In a professional environment, the concepts of roof and roof have completely different meanings. The roof is an upper enclosing structure that absorbs wind and snow loads and protects the building from precipitation and sudden fluctuations in the outside temperature. But the element that protects the building from the penetration of atmospheric precipitation is called the roof. Both in the segment of low-rise construction, and in industrial and civil construction, similar requirements are imposed on roofs. They must be strong and durable.

To ensure reliable waterproofing of the roof, there are many proven, high-quality materials that differ in the method of installation, operating rules and areas of application. TECHNONICOL roofing materials are characterized by consistently high quality, manufacturability during use and long service life.

In the segment of industrial and civil construction, bitumen-polymer materials and PVC membranes are most in demand, and coatings made of mastic are also popular. In low-rise construction, in addition to roll materials, pitched roofs are actively used piece materials... One of the most demanded in terms of durability, reliability and aesthetics is shingles.

The use of new generation materials for roof waterproofing guarantees the strength, reliability and long service life of the roof. In some cases, the warranty period reaches 60 years. Depending on the type of roof, it can be laid on various bases: wood, metal, concrete.

Mastic roof

Mastic roofs allow you to install a uniform coating, without seams. Such a composition is applied in layers, and does not require special preparation before starting work. The mastic has good adhesion to concrete, various metals and bituminous materials.

Cold mastics contain a solvent, and therefore the application of such compositions must be done in a thin layer. Otherwise, the top coat of the applied composition will harden, thus clogging the inner layers, from which the solvent will begin to evaporate over time. Layer thickness should be in accordance with the manufacturer's recommendations. Laying subsequent layers is possible only after the previous ones are completely dry. Any light-colored cloth or glove can be used as a control. It is enough to apply it to the treated surface. If there are no marks on the fabric, then you can start applying a new layer.

Some types of mastics imply the application of additional protection against ultraviolet radiation, which is necessarily indicated in the instructions for use. For this purpose, sprinkles, for example, from slate, are suitable. They are applied to the surface treated with mastic until it dries. Alternatively, an aluminum pigmented protective mastic can be used.

The use of mastic for waterproofing various roofs is justified for both residential buildings and industrial structures. It becomes especially relevant when a lot of different building structures(extension cables for antennas, equipment supports).

Bitumen-polymer roll materials

TECHNONICOL offers a wide range of modern roofing and waterproofing roll bitumen-containing materials produced on the basis of fiberglass, fiberglass, polyester.

Polyester is elastic, chemically inert, well impregnated with a bitumen-polymer composition, in percentage terms, the relative elongation of a sample of material with a polyester base reaches 30-60%. For these reasons, bitumen-polymer material with a polyester base is used in almost any solution.

Fiberglass is considered the most durable base, but the fiberglass base is well impregnated with a bitumen-polymer binder, but is less resistant to tearing.

The undoubted advantage of bitumen-polymer materials is their strength and vandal resistance. The thickness of the waterproofing carpet with bitumen-containing materials on a flat roof ranges from 5 to 8.2 mm. As you know, the thicker the coating, the more difficult it is to damage it.

The important advantages of bitumen-polymer membranes include biostability, high heat resistance, resistance to frost and ultraviolet light (due to the use of durable slate dressing on the upper layer of the waterproofing carpet), which is important in the conditions of the harsh Russian winter in the north and hot summer in the south.

Currently, the assortment of TECHNONICOL bitumen-polymer materials has been expanded with a range of self-adhesive materials intended for work in the field of ASG and low-rise construction. For their installation, it is enough to remove the anti-adhesive film from the self-adhesive bitumen-polymer layer and attach the material to the surface. Such materials are perfect in cases where the use of open fire is impossible, for example, when installing on a wooden base. In addition, the self-adhesive base greatly simplifies the installation itself, since it does not require special skills and additional equipment.

Polymer membranes

Polymer membranes are a modern roof covering made from high quality polyvinyl chloride with the addition of modern additives and plasticizers. PVC membranes have the highest flammability group for polymers G1 with a thickness of 1.2 mm and a group G2 with a higher thickness. The exception among TECHNONICOL PVC membranes is LOGICROOF V – RP 1.5 mm. She passed the tests by two methods and received the highest class Broof (t1), Broof (t2), Broof (t3).

Installation of polymer membranes is carried out in a fire-safe way - the canvases are welded with hot air, without the use of open fire, using special automatic equipment. This reduces the influence of the human factor, and also provides one hundred percent reliability of welds. Membranes are used on a wide variety of roofs of any shape and structure, and color solutions allow you to highlight the roof and create a unique pattern or logo that will be noticeable from a bird's eye view.

Flexible shingles

Shingles are a popular material in the low-rise building segment. At the heart of each shingle is a heavy-duty fiberglass mat, coated on both sides with a bituminous binder. Top dressing made of natural stone provides durability, resistance to mechanical stress and ultraviolet light. The unique formulation of bitumen, which is part of the shingles, allows the shingles of the shingles to be sintered, forming a homogeneous connection on the roof, which ensures absolute tightness. Flexible shingles are silent and flame-retardant, in addition, colored stone granules retain color stability throughout the entire service life.

The aesthetics of shingles can be highlighted in a separate line. The TECHNONICOL assortment includes 14 collections in 70 colors and 8 cutting shapes. Such a variety of shapes and colors allows you to implement any architectural solution and maintain a bright appearance facility for the entire period of operation.

The article tells how to choose and buy the right waterproofing for the roof. What factors should be considered first of all - the purpose of materials, installation features and, of course, cost. You will learn about the differences between subeconomy and economy class materials, roofing type "standard", "business" and "premium". Options for pitched and flat roofs are considered.

On flat roofs, bitumen roll waterproofing is the most common way to create a waterproof layer.

Any modern system the roof of a private house includes a layer of waterproofing. Only for some types of flat roofs are used coating or sprayed waterproofing compositions based on bitumen or its modified versions. In the vast majority of roofing systems, roll materials perform this function.

Waterproofing functions for flat roofs

At first glance, it seems that roll waterproofing, as a separate layer, is not needed here. After all, the roofing, according to its purpose, belongs to waterproofing materials.

For flat roofs using "soft" bitumen-containing roofing materials, this is the case. But provided that the roofing cake consists of one waterproof layer - the top. And if you look at the description of their structure and composition, you can see that they are very similar to similar materials used for waterproofing the foundation, basement of a house or the floor of a room with a "wet" mode of operation. The principal difference lies only in the fact that such a roll waterproofing for the roof has an upper dressing, which protects bitumen from the destructive effects of the sun and improves resistance to mechanical damage (increases wear resistance).

In two-layer types of flat roofs, the protective functions are redistributed. The top coat also remains the main layer, which completely absorbs the effects of precipitation, ultraviolet radiation and mechanical stress. And the lower, purely waterproofing layer, but without sprinkling, "insures" the upper layer from leaks in case of violation of its integrity. This is the device that TechnoNikol recommends when arranging new and repairing old flat roofs.

Functions of waterproofing pitched roofs

With pitched systems, not everything is clear.

Mansard roofs, regardless of the materials of the roof, in the composition of the "pie" have a waterproofing layer to protect the insulation from getting wet. These are vapor-permeable membranes that protect the insulation from getting wet, but allow moisture to escape from it.

Cold roofs with metal roof require the obligatory arrangement of a waterproofing layer made of polymer films. And it's not even the "piece" nature of the coating, the tightness of the joints of which is not always perfect. In this case, it is important to protect the inner space of the attic and the rafter system from condensation, which forms almost daily on the inner surface of the roof during daily temperature drops.

This is how condensation looks like on the inner surface of a metal roof. Source decorexpro.com

Ondulin and slate on cold roofs can be laid without waterproofing - condensation does not form on their surface. But the manufacturer himself indicates the lack of reliability of such roofing cake and recommends it as an economy option. For example, for garden houses and unheated household buildings. For residential buildings, waterproofing is recommended as an additional protection against leaks.

Under the modern ceramic tiles the technology is used to lay polymer films. And the lining carpet under the soft tiles is one of the types of roll waterproofing for the roof on the continuous sheathing of the pitched roof.

Roll-up waterproofing for flat roofs

Roll materials for roof waterproofing can be divided into several groups by price. To be precise, the division takes place according to the service life guaranteed by the manufacturer. And the reliability and service life depends on the base material, the composition of polymer modifiers and mineral additives in bitumen, and the total thickness. Together, these indicators determine the tensile strength, elasticity, the lower limit of the "flexibility" temperature, the upper limit of temperature resistance and the degree of water resistance at a certain value of the pressure of the water column.

Another domestic manufacturer, JSC Orgkrovlya, has four groups: economy, standard, business and premium.

The Filikrovlya group of companies offers in the catalog three groups of roof waterproofing, the prices of which are defined as "standard", "business", "premium".

On a note! One and the same "main" name waterproofing material differs in cost not only depending on the thickness, but also on the nature of the top coating. If it is for the top layer soft roof, then in its lettering there is a letter "K", which can be interpreted as "crumb" (another term is "granulate"). The price of such a coating is 10-15% higher than that of rolled waterproofing of the lower layer, in which the letter "P" is present in the marking instead of "K" - a film (for roofing material and rubemast instead of a talcum film).

The film, which protects the material from sticking during storage and transportation, melts easily when heated with a gas burner Source ctd.volokno.ru.net

Below are the prices for 1 m 2 of the main types of waterproofing materials of domestic manufacturers. The indicated cost, although it is "approximate", allows you to estimate the level of costs for materials.

When calculating the cost of roof waterproofing, it is necessary to take into account the overlaps between the panels and on the surfaces adjacent to the roof. Side overlaps for two-layer laying should be at least 80 mm, for single-layer (materials marked "solo") - 120 mm. End overlaps (strip elongation) are at least 150 mm. Joints to vertical surfaces are made in two layers with separate canvases. The first layer must have a horizontal part of at least 150 mm, and a vertical part of at least 250 mm. The second layer should be larger than the first: horizontally - by 100 mm, vertically - by 50 mm.

The edge of the side overlap is often marked by the manufacturer on the roll itself. Source legkovmeste.ru

Roll-up waterproofing of pitched roofs

If you omit the polymer films and membranes that are attached to rafter legs pitched roofs, that is, the only type of bitumen-based roll waterproofing is underlay carpets for bituminous shingles. Even the very type of roofing is nothing more than roll roof premium class with stone granulate sprinkling, which was cut into small plates with curly cutouts. And when folded, it mimics the classic ceramic roof.

Due to the "small" size of the plates and the piece-wise laying of soft tiles on a solid base, this type of roofing material for pitched roofs has its own waterproofing technology. V mansard roofs a superdiffusion waterproofing membrane is laid on top of the insulation, a wooden block is attached to the rafters (provides a ventilated gap), and is attached to the bar solid crate, on top of which a lining carpet and soft tiles are laid. At cold roofs, a continuous crate, underlay and tile are immediately mounted on the rafters. That is, regardless of the presence of insulation, this roof always has a "separate" layer of rolled waterproofing - lining carpets.

The attachment points of the lining carpet to the base are additionally coated with liquid waterproofing Source 4handsmaster.com

Underlayment carpets are fixed to the substrate using mechanical fasteners. For roofs with a slope of more than 18 °, only valley carpets are required, which are laid in places of the most probable leaks: on valleys, ribs, ridge. The TechnoNikol company for this type of rolled roof waterproofing has a price for 1 m 2 - about 400 rubles.

On slopes of roofs with a slope of 12 ° to 18 °, "ordinary" lining carpets (not counting the valley) are laid. Their price is comparable to the cost of premium roll waterproofing - about 150 rubles / m2.

Conclusion

This small overview shows the prices of bituminous-based waterproofing roll materials for all types of flat roofs. Moreover, the cost range covers the materials of the lower and upper layers of a standard roofing cake. And although modifications of the lower layer are cheaper than the upper one, the cost per square meter, in actual assessment, should be doubled along the upper bar due to overlapping tolerances. It is possible to reduce costs by using “solo” materials, which are laid in one layer, but we must remember that the reliability of such a roof will be lower. And in any case, an accurate calculation of costs under the item "roll waterproofing" can only be given by specialists in the design of the roof.

The tightness of the roof is the most important condition for the durability of the building and the comfort of living in it. Currently, the industry produces a wide range of special high-quality materials that allow reliable waterproofing of all types of roofs, regardless of climatic zone location of the building.

Roof coverings cannot guarantee tightness without additional construction measures, especially for technological and engineering communications. Flat and sloped roofs have their own technology and waterproofing materials.

When choosing specific types of waterproofing, you need to pay attention to the following parameters:

• practicality and economy;
• manufacturability and maintainability;
• safety and environmental friendliness;
• cost and time of operation.

Each type of roof has its own architectural features, which affects the materials of manufacture and application technology. To facilitate the selection, we recommend that you familiarize yourself with a short list of well-known brands.

Waterproofing materials for flat roofs

When choosing waterproofing materials for flat roofs, one should be guided by the provisions of SP 17.13330.2011. According to regulatory enactments, on roofs with a slope of 1-6 °, it is allowed to use rolled bitumen and bitumen-polymer materials with a protective coating of the outer surface with fine-grained dressing, for roofs with a slope of up to 14 °, it is allowed to use waterproofing materials with a coarse-grained dressing. Polymer coatings allowed to be used for flat roofs with a slope of at least 1-3 °.

Currently, several types of waterproofing are used for flat roofs.

Prices for coating waterproofing

For example, consider the option of waterproofing a flat roof with the most modern roll material based on durable synthetic fabrics, a coating with modified bitumen.

Step-by-step instructions for waterproofing flat roofs

Statistics show that about 80% of leaks on flat roofs are not due to the materials used, but due to technological errors of builders: the wrong choice of waterproofing materials, incorrect implementation of the mating angles, poor-quality base preparation, bad weather conditions during the production of work, etc. e. Technical indicators of modern waterproofing coatings give guarantees of operation for at least thirty years, but only if they are correctly applied.

We carry out waterproofing of a flat roof (in this case, a garage)

Step 1. Decide on the choice of materials. All roll waterproofing materials are divided into two classes: bituminous and bitumen-polymer. The latter, in turn, can be made from SBS or APP modified bitumen. If the house is located in a region with a warm climate, then choose materials based on AMS, they are more resistant to high temperatures and will not leak during heating in summer. For cold climates, a material based on SBS is better suited, this bitumen modification retains elasticity when low temperatures and does not crack in winter period... Calculate the roof area, buy the required amount of waterproofing, taking into account the width of the overlap and floors. Each roll has a mark indicating the overlap line of the rows.

What is required for work - waterproofing for a flat roof, bitumen primer, rollers, roofing knives, trowels, brushes

Step 2. Prepare the base of the roof. On an improperly prepared substrate, the service life of roofing is significantly reduced. What are the requirements for the foundations?

Step 3. Prime the roof surface. It is recommended to use bitumen-based materials as primers. The primer must be done carefully, leaving no gaps. Various joints and corners should be treated with particular care. Ground the vertical elements of the structure to the height of the roll establishment.

Step 4. Proceed with the installation of the waterproofing layer. The recommended side overlap is at least 8 cm, but each manufacturer can change this parameter. Pay attention to the markings on the rolls, there are special lines or other marks to control the overlap. End overlaps ≈15 cm, while placing them at a distance of at least 50 cm from each other.

Practical advice. It is recommended to lay roll-up waterproofing materials based on bitumen in two layers, the second should be done with an offset so that the overlap seam is located in the middle. The permissible distance between the side joints is at least 30 cm.

If you plan to make two layers, then the first should be without sprinkling, due to this, adhesion increases and tightness increases.

Step 5. After the base is dry, roll out the first roll on it. Adjust its position for overlaps and overlaps. If everything is normal, roll it up carefully, for ease of use it is recommended to use metal pipe appropriate length. Be careful not to change the position of the bale during rolling.

Step 6. Cut the protective film and, carefully peeling it off, begin to roll out the roll.

Vertical architectural elements must be even and smooth, piece masonry materials must be plastered. The main waterproofing carpet must be installed on vertical surfaces above the transition edge. The first layer without sprinkling should go on a vertical surface to a height of at least 25 cm, the second with sprinkling by about 10 cm. The horizontal overlap is within 15 cm. To increase reliability, it is recommended to additionally secure the upper abutment line with metal profiles. How to seal the abutment of vertical surfaces?

1. Cut a piece from the roll, its length is equal to the design vertical height plus the design length of the horizontal abutment.
2. Roll the material into a roll and stick it to the bonding area. Check the position.
3. Hold the bottom end with your foot or hand, and heat the top with a burner. Stick it on as it warms up.
4. Fold back the lower end, heat up the bitumen and glue the canvas to the first layer of waterproofing.

Practical advice. If the bottom layer at the junction has a dressing, then it must be well heated with a burner, and the stones are pressed into the bitumen with a metal flat spatula.

Funnels for water drainage should be located at the same distance, at least two drainage points must be made in each area. Waterproofing technology depends on their design and manufacturer's recommendations.

Pitched roof waterproofing materials

Pitched roofs have a rafter system, roofing can be made of soft and hard roofing materials. Waterproofing should be selected taking into account the architectural features of the rafter system, the type of roof (warm or cold), the angle of inclination, etc. Another important point – rafter system designed for a certain weight, it is not recommended to increase the weight of the roofing cake... Accordingly, waterproofing for pitched roofs should have a minimum specific gravity. Today, there are the following types of hydroprotection in implementation.

For an example of waterproofing a pitched roof, consider a membrane waterproofing option.

Step-by-step instructions for waterproofing pitched roofs

Let's talk about the most complex and expensive technology for installing waterproofing on pitched roofs... In practice, some steps can be skipped, the quality of the roof will not suffer from this.

Step 1. Attach a drip tip to the windshield with self-tapping screws, water from the waterproofing will drain onto it. The drip is sold complete with roofing or separately. The specific design does not matter, they all perfectly fulfill the assigned tasks.

Step 2. Place butyl tape on the drip tip and thin double-sided tape on top of it. These elements are needed to securely fix the edge of the waterproofing membrane and prevent it from being torn off by gusts of wind.

Step 3. Begin laying the membrane. The edge should be glued to the drip tip, the outlet above the wall should be at least 15 cm. Carefully roll out the roll, the slightest mistakes at the beginning of work will cause large discrepancies, it is impossible to correct them without bending the material. We'll either have to leave it in this position, or start all the work from the beginning. Fix the membrane to each rafter with a stapler. The number of staples does not really matter, in the future, the material will be additionally pressed by the counter batten.

Practical advice. In order to facilitate the process of gluing the material to the drip, it is recommended to temporarily fix the boards to the rafters to support the legs. In the future, they will be removed, in their place a counter-lattice and a crate will be nailed.

Step 4. After the first row of waterproofing has been installed, start attaching the counter battens with battens approximately 20 × 50 mm. It is recommended to glue a special sealing tape to the bottom of the rails, it will tightly close the holes from under the staples and will not allow water to enter the rafters.

Fasten the counter grill with self-tapping screws or ordinary smooth nails. The first type of hardware is currently very popular, but it is expensive and difficult to work with. Professionals always use nails, the fixing strength is quite enough, the crate will not go anywhere.

Step 5. Attach the crate to the counter lattice, it is easier to arrive from top to bottom. Before starting work, prepare a stubborn board, it should rest against the screws. Pay great attention to the stability of this board, do not violate safety regulations.

We have already mentioned that this technology is the most complex and costly. In practice, builders do not install a counter grill. Why? The purpose of this element is to provide ventilation between the roofing sheets and the waterproofing. We assure you that the battens provide the same effective ventilation. There is no need to waste time and money on Additional materials and construction operations.
