A quality roof means also aquality way of living, so money for the roof isn’t the one you should spare!
By its form we divide roofs into one layer, a double layer or a multiple layer kind of roofs. They could also be with semi slopes, complex, tents, conical,shell,dome, tower, flat and curtain shape. The slope of the roof and its construction are determined by the type of cover material, purpose of the attic space and aesthetics demands, a very important are climatic conditions, too.
For example, where the winters are snowy, roofs are steep, while in warmer regions, because of the barrel, theyare often straight. For a high quality roof we need good design , good quality cover , but also a handful of additional materials that will allow you to regularly ventilate the attic , which have to be well insulated and protected of the storm water. Durable roof has to be dry. In order to ensure the protection, efficient hydro-insulation is not sufficient. Therefore, in order to ensure proper drainage of excess moisture and water vapor in the environment, it is necessary to provide proper ventilation of the roof thus prevent even the slightest moisture.
Retrofit vented roof
Double ventilation roof: below and above initial panel cover. The initial cover and the panel should be open to the reef in order to ensure proper air circulation under the boards and thus took the moisture out of the area of thermal insulation. Between the plates and heat insulation there is a need of forming vents.
There is double ventilation roof: below and above the initial cover. The initial cover should be opened in the reef in order to ensure proper air circulation above the thermal insulation and thus took the moisture out of its area. Between foil and heat insulation there is a need of forming vents.
The other type is single ventilation of the roof. Low pressure results in leakage of the roof membrane and unrestricted transfer of moisture over the initial cover into the environment. The initial cover in the reef should not be open due to the fact that leaking reef to protect from atmospheric precipitation. Lack of additional air vents has the advantage of saving energy (which is used for heating the attic) – thermal insulation is not cooled by the air circulating.
In preparing the roof you should stick to the rules of the profession. Each cover was to shingle or tile has its own peculiarities. It is worth mentioning that there is a difference in isolating classic roofs or flat – green roof, which has ingrained ventilated system classic pitched roof;it is designed to provide a circulation and air exchange between the building and nature in order to provide a better climate for life in the facility.
