If ominous spots with stains appeared from the ceiling or on the plaster, you need to engage in waterproofing of the roof as soon as possible. The bottom line is that if you get by with a superficial repairs or to close your eyes to a small “leak”, after some time you will have to invest a more significant amount in the house-water that has fallen under the roof and insulation, will entail corrosion of metal parts, wood rot, mechanical ones destruction due to the intentions of ice and a whole bouquet of troubles. And the most unpleasant thing is that it will be cold inside the house, because wet insulation copes very poorly with its tasks.
To begin with, it should be understood that complex waterproofing with only the sealing of holes and sealing the roof is not limited. Of course, the main task is to protect the insulation, rafter structure and attic from snow in winter and rain in the summer. But in addition, moisture under the roof is formed from the side of residential premises, is the result of the fumes of wooden structures and t. D. Therefore, full -fledged waterproofing should include the construction of a vapor barrier barrier, as well as a thoughtful ventilation system, in which the moisture falling under the roof would be removed out.
Briefly, the waterproofing system looks like this: a crate is built under the roof, on which a waterproofing film is installed. A layer of insulation is installed under the film, which is protected from the inside with a vapor barrier barrier. A ventilation gap is made between the film and the insulation for the output of moisture, often the insulation layer is also covered with a membrane film, in which moisture is removed from the insulation in one direction. All this forms the so -called “roofing pie”, the design of which for some developers may differ slightly.
Naturally, if there is no dwelling under the roof, but there is a cold attic, then a layer of insulation and vapor barrier barrier is absent and everything is limited to the use of the film to protect against moisture and wind.
It is worth noting that the choice of materials for waterproofing the roof, as well as membranes, is very large today. For example, if the roof is covered with a metal tile or other metal coating, the film should be anti -condensate, otherwise the roof may suffer from corrosion. If natural tiles are used as a roofing, based on bitumen or ceramics, diffusion membranes are widely used. Also today, a huge selection of vapor barrier materials and insulation – while the main criterion when choosing is the mass, quality and environmental friendliness. Regarding prices, almost all materials for complex waterproofing have a well -known rule: the more expensive, the better.
Work on roof waterproofing is best done in summer or spring, while it is important to have an accurate weather forecast, since any rain or wind can ruin everything. The air temperature should also be high enough to exclude the appearance of the fog in the morning or the loss of dew. If the roof is cold and without insulation, then waterproofing can be carried out in the winter.
After the work on insulation and waterproofing is completed, it is important to inspect the condition of storm drains, carefully view the joints between the pipes so that it does not flow anywhere and the water does not fall, for example, into the end of the roof. The condition of the roofing should also be perfect – if there are broken sheets or tiles, they must be replaced or poured.
With properly made roof waterproofing in the house, you can live for decades in warmth and tranquility, occasionally superficially controlling the state of the roof.
