The pitched roof has its name due to the features of its design, since it consists of planes – slopes that have characteristic angles of inclination. Such roofs are divided into two types: a separate nature, or as they are also called attic and combined (unchilding). The first type assumes the presence of non -residential attic located between the ceiling and the roof. In the second case, the supporting elements are simultaneously an overlap for the upper floor in the house.
Raise roofs have a slope, the level of which depends on the effects of many factors.
Roofing material. Each type of coating is designed for the features of the angles when tilting the roof. We recommend sofitis.
The architectural features of the house. The volume of the building is often solved by its roofing.
The amount of precipitation of this region. With snow winters, it is necessary to make a larger angle of inclination.
Before installing the pitched roofs, you need to know a number of design features. The rafter leg should have a massive section, which will make it possible to withstand the general load on the roof. If the angle of inclination of the roof is exceeded more than fifty degrees, the best solution would reduce the section of the rafters. With a gentle roof, on the contrary, it is necessary to increase the cross section of the rafter supports. In addition, it is worth considering that the durability of the roof is determined by the life of the house itself.
It is important to remember that the component of the peculiarity of the rafter system is its property to ensure stability from the fire. Based on this, the roof should have the corresponding bearing capacity. This means that the roof should withstand the weight of snow, material and its own. If a fire arises, the roofing according to sanitary standards retains its integrity for a period of time, which is within the framework of the fifteen and forty -five minutes. To achieve this, it is necessary to provide roofing material with reliable protection, namely: processing with special means.
And finally, the more the roof is insulated, the more significant its weight, therefore, the cross section should also increase.
Installation of the pitched roof dependent on the characteristics of its internal and external constructions. The task of supporting internal structures is to achieve the reliability of maintaining the roof. After determining the internal elements of the structure of the rafter system, it is worth proceeding to the question of further roofing and external frame of the pitched roof.
