Roofing works — load-bearing system and ventilation

Get Free Consultation

Roofing works are one of the most important in the construction of houses and structures, as they make it possible to protect the finished structure from various environmental influences, and also play an important role in the attractiveness of the exterior of the house.
Any roof covering always relies on a load-bearing coating that transfers the weight of the roof directly to the building elements. The main parts of the roof's supporting structure are trusses and crates. The most common form of a rafter structure is triangular, as it is economical and provides sufficient structural rigidity.
A crate is a beam laid perpendicular to the rafter trusses and directly absorbing the load from the weight of the roofing material. It can be solid and sparse. The solid one consists of two layers arranged at an angle of 45 ° to each other, and has a gap between the bars of no more than 1 cm. As a rule, a solid crate is used for asbestos-free slate, metal tiles and a soft roof. For roofs made of asbestos cement sheets, steel and clay tiles, a sparse crate is used in 3 – 4 cm increments. Most often, supporting structures are made of coniferous wood, and metal and reinforced concrete structures are used as supporting elements in block and brick houses.
A very important point in the production of roofing work is to ensure sufficient ventilation of the under-roof space. For this purpose, ventilation openings are installed in the area of the cornice and roof ridge. The temperature in the attic, if it is uninhabited, should be 5 – 6o higher than the temperature outside. Insufficient ventilation of the under-roof space can lead to a violation of the necessary temperature and moisture parameters. This, in turn, can cause rotting of the supporting rafter structure and roof collapse in the future.
Roofing is a complex process that requires certain knowledge and skills. Therefore, it is advisable to choose organizations and enterprises that are well-established in the market of providing such services for roofing work. They must have skilled and experienced specialists, be proficient in traditional and new roofing technologies, and have sufficient material and technical resources.
