Roof waterproofing is designed to save roofing materials, as well as rafters, from the effects of precipitation and reagents that can be dissolved in them. This is done using a huge amount of mastics and polymeric materials, as well as various bituminous mixtures. The choice of mastic affects the durability, as well as other protective properties of the structure. Roof waterproofing can be carried out using traditional methods or advanced technologies, which differ not only in cost, but also in labor intensity.
After building a house and installing a roof, the structure is protected from precipitation. When using the so-called cold roof, everything will be fine, it will always be dry, so there is no point in insulating it. A completely different situation is with the insulation of the roof, which will be carried out after some time, especially if something non-frost-resistant is stored under it. Here the question arises as toHow can roof waterproofing be done? It is worth saying that it is not so difficult to do it yourself.
Previously, roofing material or other waterproofing material was placed under the slate, which let water through if it was not laid correctly or there were holes from nails. At the moment, there are a lot of modern materials in the form of films that can perform their functions with high quality. Such materials mainly consist of propylene and non-woven fibrous material. Such a film is laid glossy up. In this case, the material will let air through, but will not let water through, and neither rainwater nor condensate will be inside the roof. The appearance of any condensate inside can only be due to the fact that conditions are created in the roof that favor its appearance, that is, the dew point. In the case of a cold roof, this option is excluded, since it is well ventilated, and the temperature inside is the same as outside.
The waterproofing film has an anti-condensation layer on the bottom non-glossy side, consisting of pile. Such a surface, like a sponge, absorbs a large amount of moisture, eliminating its excess from a warm roof. Moisture dries out safely when humidity levels change. You can attach the insulation to an already finished roof. It's quite convenient.
Waterproofing the roof of a garage or other structure can be done by two or more people, which greatly speeds up the process. When the film is fixed, the edges should be trimmedconstruction knife. After that, you can begin to fix the crate from the outside. And from the inside you will need to fix the counter-lattice. For this, slats of the same width as the rafters are used, fixed with stainless steel screws. Each layer of film is laid with an overlap of approximately 10 centimeters (at least). For additional insulation, the joint is glued with adhesive tape.
Waterproofing a flat roof is essentially no different than other roof types. This process is quite long and laborious.
While roof waterproofing is a complex process, the result is worth it!
