Roof construction: features of a reliable roof device

The design of the roof largely determines the appearance of the building, the comfort and safety of staying in it. In addition to the main coating, this system contains a whole complex of important components and additional materials - vapor barrier, ventilation elements, waterproofing, various heaters. All of them perform the most important functions to ensure the safety of the structure and create a microclimate inside the house.

The exclusion of any element of the system or its incorrect arrangement will be disastrous not only for the entire structure, but also lead to a general destruction of the building and, as a consequence, to the need for serious and costly repairs, because the roof construction plays a key role in protecting the structure from all sorts of natural influences.

All "roofing pies" according to the principle of their design have very significant structural differences due to climatic and operational conditions, as well as the type of building. In this regard, each roof construction is unique and has especially individual conceptual features.

All types of roofs can be very conditionally divided into flat and pitched. Sufficiently widely used, both in industrial and residential buildings, the construction of a flat roof is often mounted either on flat roofs or on roofs with a minimum angle of inclination. Such a system of covering the building provides for the use of bitumen or roll materials.

The surface of the base for the device of this type of roofing structure may be floor slabs, a flat wooden or metal platform, as well as an asphalt concrete screed. However, the roof structure is never completely flat. An inconspicuous gradient (up to five degrees) in the direction of the center of the roof should always be present. The purpose of such deviations is to discharge rainwater into the funnels of the drainage system. Sometimes it is advisable to equip such roofs with a rainfall system of emergency discharge of rainwater.

Unlike flat roofing systems, the construction of pitched structures must necessarily include load-bearing structures, ridge elements, crate, and other components. Such wooden roof constructions, except for wood, imply the use of metal profiles or reinforced concrete base as bearing elements.

The abundance of coating materials used in the arrangement of this type of roof is also impressive. This and almost all types of shingles, and profiled, and slate and much more. The interiors of this multi-layered "roofing pie" are filled with heat-insulating materials. Between all the components of such a complex roof structure, a clear relationship is evident. A poor-quality installation of at least one of them will disrupt the functionality of the entire system and will have a very negative impact on the operational characteristics of the structure.

If we represent a roof -type roof arrangement in the form of a complex of different systems, the following structural sequence is formed: the rafters system, the vapor barrier, the thermal insulation, the waterproofing, the ventilation of the under-roof cavity, the outer covering and the drainage system.
