Waterproofing roof - one of the essential steps of its care.Edit the roof so that it is not leaked after the first long shower - an extremely important task.Who wants a month or two, half a year, then go to the roofing works to stop the leak?Therefore, we do everything at once, thoughtfully, using high-quality modern materials.
Before settling on different types of roof and waterproofing technology to consider waterproofing the roof, stipulate which are generally roof.For waterproofing solutions will vary from a flat or pitched roof you erect.Waterproofing flat roof and pitched roof waterproofing differ both materials and method of installation.
On how will quality waterproofing the roof with his hands or held by experts, roofers, insulation and security depends, and the performance of the entire roof.At the same time, remember that moisture can come from outside as well as in the form of steam, is collected in a roof space.

materials for waterproofing roofs
they are divided views on the composition and method of application:
- waterproofing perforated film (gidrobarer), anti-condensate film;
- polymer films - membrane (PVC-membrane, EPDM-membrane, spinous, superdiffuzionnye membrane);
- hydrophilic rubber;
- surface waterproofing (acrylic, bitumen, silicone rubber, polyurethane mastic, one- and two-component materials);
- sprayed waterproofing materials (polyurea, acrylic two-component formulations, the liquid rubber);
- injection materials (polyurethane, acrylic, silicate resins, cements, emulsion);
- penetrating materials (semiconductor materials and penetration).
One of the newest technologies on the market today waterproofing materials.There are PVC membrane, PDM-diffuse membranes and membrane.
last such species are:
- diffuse with micro;
Diffuse membrane with the presence of micro perforation and superdiffuznye suitable for all types of roofs.For the membrane with micro essential installation leave a gap between the material for waterproofing roofs and thermal insulator for superdiffuzionnaya such a gap is not necessary.Superdiffusion membranes are best suited for attics, anti-condensation membrane in which the non-woven fabric absorbs the entire condensate - the best option for the roof of metal.
membrane life - up to 25 years.They are durable, have a fire and environmental safety.
versatility and PVC membranes.This is a good material for building a new roof, and to repair the old one.Waterproofing of the roof, the cost of materials for which the impressive, with such membranes will become a pleasure.Since this is done one time in 25 years, it is important to pick good people.They are a means of welding and create lasting waterproofing coating.Such film consists of three components: a specific color PVC layer, the layer reinforced polyester and another gray, PVC layer.
sale membranes in narrow rolls.They are attached by means of mechanical, methods of ballast or stuck.The ballast method - for roofs with roof pitch of up to 10%.The membrane was placed on the roof, reinforce the perimeter webs poured gravel or crushed stone.It is often used in the construction of a method of stripping the roof.If you create additional pressure on the roof can not use mechanical fasteners: nails, screws, staples.If the roof has a complex configuration, the membrane is adhered.
PDM-membrane not only multifunctional (suitable for all roofs): they are suitable for most roofs and arched curves, any angle of slope.Sheets membranes stacked one by one, and in the joints provided adhesive tape.
If such a membrane used for the installation of waterproofing flat roofs, the top is covered with a layer of loose material.On pitched roofs panels are fastened or stuck.Such material nor cold, nor the sun are not terrible: it will last 25 to 50 years.Due to the elasticity of the membrane can PDM-elongated 250-300%, taking the shape of the surface being coated.The sharp ends of the roof and the chemicals in the form of petroleum products (fuels and lubricants) and oils are harmful for the membrane.Also, it needs to be further processed acrylic coating and from time to time to update it.

First of all bitumen and containing by-products.On the surface of the coating is created from 5 mm to several centimeters.Over time, the bitumen loses plasticity and mechanical action can be destroyed.Lifetime - approximately 5 years.
bitumen-polymer mastic - a new generation of surface waterproofing roof.Price for works on an area of 1 sq m.It varies between 30 and 100 dollars.
Mastic is applied to the flat roof or roof with a minimum angle of inclination.On the composition of mastic materials are bitumen-polymer, polymer, bitumen-rubber.By way of application, they are divided into hot (the ones that need to preheat to 160 ° C) and cold mastic (they do not need to be heated at a temperature from + 5 ° C and requires warm up to + 70 ° C if the temperature is below + 5 ° C).
Mastics perfectly adhere to the substrate, be it concrete, wood, metal.When they harden, creating a continuous, seamless rubber-like coating, the service life is not less than 20 years.Yet this type of waterproofing called tanker roof, and the technology of its application is similar to creating self-leveling floors.
This application of bitumen and polymer coatings, paints, emulsions for coating.Waterproofing Paint can be applied by hand or spray.Do it in 2-4 layers for greater strength.The thickness of the waterproofing layer - only 3-6 mm.Over Freshly insulation sprinkled fine sand with the aim to cement coating.The promised service life - 5 years.When selecting materials for roofs need to give preference to the plasticized polymer modified compositions.
to work on the roof waterproofing paint prices many times more than obmazochnuyu.This is an average of $ 100 per 1 sq.m.
This method - one of the oldest.It involves the use of sheet and roll materials: tar paper, glassine, roofing, steklovoyloka, Isola, waterproofing, Brizol.From newer - is vinyl liner, polyethylene, polyvinyl chloride, isolayer, mostoplast, izoelast, Ecoflex.
surface in this case must be dry and very smooth: permitted irregularities up to 2 mm.After aligning and cleaning the surface of the soil cover its layer of asphalt emulsion, and then paste the material.The sheets are placed overlap of 10-15 cm. This waterproofing is sensitive to mechanical damage and difficult to install.At the end of the work it needs to be sprinkled with rock dust.At this temperature and for mounting of the material should be at 10 ... 15 ° C.But the cost of the work on this type of waterproofing about $ 10 per 1 sq.m.
This type of waterproofing is applied on previously cleaned surfaces with a porous structure.These include: concrete, limestone blocks, brick.Impregnation fills pores and cracks, penetrates deeply and, freezing, such isolation is not only prevents the penetration of moisture, but also strengthens the entire structure.As an impregnating waterproofing used water glass, liquid polymers, synthetic resins and molten bitumen.For the application of the compositions used sprayers.The foundation must be carefully cleaned and degreased, the composition was able to penetrate into the pores of the crystals and form there.After this treatment, water skvozt cement concrete does not leak.
This is the easiest and cheapest way of waterproofing, which is used for pitched roofs: a slate, shingles, metal roofing.It is used for insulation of attics and lofts with mineral wool and polystyrene.
pitched roof waterproofing is laid, starting from the eaves toward the ridge.
If the angle of inclination of the roof of 30 degrees, the overlap between waterproofing make a film of 150-200 mm, if the angle of 15 to 30 degrees, the overlap should be about 250 mm.When this material should not be stretched: it should sag between the rafters 15-20 mm.
We stopped for the most common groups of waterproofing materials.Now let's look at where some of them are better used.
How to waterproofing the roof?
For waterproofing of the roof, which will be warmed polystyrene , in some cases, a waterproofing film , and in some - nothing.Expanded polystyrene itself, with sufficient insulation joints can serve as a good waterproofing.
If you want to insulate and protect from moisture flat roof or make her inversion, it is possible to use different types of membranes in conjunction with insulation.Even more simple version for flat roofs - filler insulation in the form of same mastics .At the same time the use of mastic important as new roofs and for sealing joints. liquid rubber on a flat roof - is also a great option.
If you stop your choice on rolled materials and will carry out their installation, then pay attention to the roofing material, and new items - and evroruberoid rubemast.If you plan to equip the attic attic , in combination with a vapor barrier and insulation can be applied superdiffuzionnaya membrane .Option excellent, but not cheap.When roofs of complex configuration is membrane - the most acceptable option.
Experts say that with proper installation of slate, no waterproofing is not required.By Slate once lozhili roofing now - it gidrobarer or perforated waterproof film.The same material is used and under the metal.
this film is fastened to the rafters for pitched roof or on the ceiling joists.Building hardware used to connect the building elements.As fastening tools used staples or nails made of stainless steel, mounted auxiliary crate of rails.For non-insulated attics such a film in conjunction with insulation - the most affordable option, providing good value for money.
roof with standing seam roof, metal and other types of metal roofing recommended anti-condensate film. for laying anti-condensate film is required and the upper and lower ventilation gap.Therefore, it makes extra crate.
to use membranes lower the gap is not needed.
With regard evroshifer and seam roof , is because they have a very good thermal conductivity, this type of waterproofing their own hands, as a diffusion membrane , does not apply.
for seam roof there bulk separation membranes. But for shale used membrane and provide a ventilation gap.
In applying the anti-condensate film such gaps should be two.
When selecting a waterproofing for the roof a lot of nuances.But above all it is:
- shape of the roof (flat, pitched, complex configuration);
- destination (operated or not);
- kind of roofing materials (slate, tiles, concrete, metal, evroshifer, rebated, shale, etc.. Kinds of roofs);
- kind of insulation.
