Waterproofing the roof is designed to save roofing materials, as well as rafters from the effects of atmospheric precipitation and reagents that can be dissolved in them. This is done using a huge number of mastics and polymer materials, as well as various bituminous mixtures. The choice of mastic affects the durability, as well as other protective properties of the structure. Waterproofing of the roof can be carried out using traditional methods or advanced technologies, which differ not only in value, but also in labor intensity.
After the construction of the house and installation of the roof, the structure is protected from atmospheric precipitation. When using the so-called cold roof everything will be in order, it will always be dry, so it makes no sense to insulate it. A completely different situation with the insulation of the roof, which will be produced, after a while, in particular, if something non-frost-resistant is stored under it. Then the question arises as to how the roof waterproofing can be made? It's worth saying that doing it yourself is not so difficult.
Previously, a roofing material or other waterproofing material was put under the slate , which let in water if it was not properly laid 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 qualitatively. Such materials generally consist of propylene and a non-woven fibrous material. This film fits glossy up. In this case, the material will allow air to pass through, but it will not pass water, and inside the roof there will not be rainwater or condensation. The appearance inside any condensate can only be due to the fact that in the roof conditions are created that favor its appearance, that is , the dew point. In the case of a cold roof, this option is excluded, since it is perfectly ventilated, and the temperature inside is the same as outside.
The waterproofing film on the lower non-glossy side has an anticondensate layer consisting of a pile. Such a surface, like a sponge, absorbs a large amount of moisture, removing from its surplus a warm roof. The moisture dries out safely when the humidity level changes. Mount the heater can be ready for the roof. This is convenient enough.
Waterproofing of the roof of a garage or other structure can be made by two or more people, which significantly speeds up the process. When the film is fixed, the edges should be cut with a construction knife. After this, you can proceed to fix the laths outside. And from the inside, you need to fix the monitor. For this, rails are used of the same width as rafters fixed with stainless steel screws. Each film layer is stacked with an overlap of approximately 10 centimeters (not less than). For additional insulation, the joint is glued using adhesive tape.
The waterproofing of a flat roof is essentially no different from the operation with other types of roof. This process is rather lengthy and time consuming.
While the roof waterproofing is a rather complicated process, the result is worth it!
