The roof is required so that it is protection for rain, snow or wind. It should also have good resistance to various mechanical damage. That is, it should provide as much comfort as possible for its owners. In general, the roof can be given almost any shape.
In a variety of climatic conditions, there are a variety of forms and types of roofs, with different levels of inclination. Where snow is an extremely rare occurrence, you can use roofs with a flat surface or with a small angle of inclination.
Where there are frequent snowfalls, you need to use the pitched roof, with a large angle of inclination. Otherwise, a lot of time will have to be devoted to cleaning the roof from snow, it will also constantly rust from constant humidity.
A roof that has a large level of inclination and is very vulnerable to the wind. She should have a very strong crate and no less strong rafters. The location of the house is also very important. If your house is located in a field or on a hill, then it is best to forget about the acute roof.
If your house has a location in the lowland, then it will be more appropriate to build a pitched roof.
A broken roof is very comfortable. At her expense you can perform an attic room, in turn due to a large angle of inclination.
