Roof arrangement is a very important point in building a house. If the roof is not made correctly and at least the main points are not observed, then we can assume that the house is not built correctly. After all, a violation of tightness, the accumulation of moisture, its accumulation can lead not only to temporary leaks, but also to the gradual, but true destruction of the whole house.
For competent roof construction, it is best to use the services of professionals. They will help to protect the house from factors such as rain, snowfall, wind, or moisture accumulation inside the house. To solve these problems, good waterproofing and vapor barrier of the roof is necessary. These layers can alternate, performing their functions. All materials that are used for the above must ensure the tightness of the roof and prevent entering the insulation. If the insulation absorbs moisture, then its properties worsen significantly, and the thermal insulation layers itself are destroyed. These materials should also provide good ventilation. Ventilation helps moisture evaporate from protective layers.
In addition, various types of roofs require different methods of insulation and isolation. For tiled roofs, the best choice will be the use of film materials. In this case, the moisture -proof layer is located immediately under a layer of tile. He is designed to protect thermal insulation from moisture from the outer layer, for example, from rain and snow, as well as the whole house. Vapor barrier is laid between thermal insulation and the ceiling. This will help protect thermal insulation from moisture, which evaporates from the interior. Some materials can also protect the thermal insulation layer from additional thermal radiation.
