Roofs that form a non -residential room between the ceiling and the roof are called attic. It is possible to make it yourself, but very hard. The base of the pitched roofs are rafters, which, due to the interweaving, create a rather complex device, which in construction is called a farm.
Often rafters or beams fit on the load -bearing walls themselves, but in order to fix them better, it is recommended to fix them on a beam built into the end wall. Choose the type of crate design should be taken into account the used roofing material. To choose a slope of the roof slope, you need to know the size of the snow cover in this region, the material of the roof and the architectural solution of this building. To date, there are three types of reinforcing the rafters of the roof:
The first type is most common — layered rafters. Their popularity is due to the presence of a convenient assembly scheme, which can be replaced at any time. The second type is hanging rafters that use if there are no internal supporting walls and the flight between them does not exceed 8 meters. This system is able to strongly load the walls. And finally, the third type is wooden farms that are very popular in the construction of private houses. They are also eagerly used in the reconstruction of old roofs.
