It is quite difficult to meet at home with flat roofs in our latitudes. The reason for this is that the roofs of such structures are not very well adapted for the conditions of harsh winters when large volumes of snow fall out. A flat roof simply cannot cope with them and breaks under a significant weight.
But this does not mean that the flat roof has no advantages that could not be used. Flat is called a roof that is located at an angle of no more than 10JNDF to the base. Since this angle allows you to significantly reduce the area of the roof surface, the roofing material requires a little. At leisure it will not be superfluous to find out what types of warm floors are this information is very useful.
In addition to efficiency, a flat roof has such a plus as the ability to withstand the effects of even very strong winds. Therefore, in windy regions, it is used in the construction of outbuildings, for which owners are quite difficult to monitor systematically.
A lot depends on what exactly the flat roof is created from. If its basis is an ordinary rafter system, then no need to think about any strength. But subject to the use of a flat roof device as a material, for example, a concrete slab, the structure comes out very persistent.
