Although roof and roof systems are very important in prefabricated buildings, it is considered an unnoticed factor or a factor that seems insignificant, but on the contrary, prefabricated or not roof systems are the most important factors for buildings. The main reasons why the roof system is important:

Ensuring the dynamics and strength of the building, especially in prefabricated systems.
Snow load, wind, rain, etc. to be based on factors such as.
It constitutes 40% of the thermal insulation of the building.
Perhaps one of the most important factors is the leading role in the aesthetics of the building.
When we list such factors, we can more or less have an idea about the importance of roof systems, but if we want to fully understand and consider prefabricated buildings, it is possible to say that roof systems in prefabricated buildings form the backbone of the building, because all parts are connected to each other because prefabricated structures are disassembled systems, but the roof system is It connects the whole structure and provides strength. Roof systems in prefabricated buildings consist of disassembled parts called "roof trusses". The system called roof truss is a material consisting of nested triangles, called trusses, and when combined, the roof system is formed. Roof trusses are produced according to the desired size and shape, and thus every desired roof model and design can be produced after correct calculations.

Generally, 4 types of coating are used extensively as roof coverings in prefabricated buildings, these are:

Trapezoidal sheet

Tile patterned sheet

Sandwich panel


If we briefly talk about these materials;

Trapezoidal sheet: They are roofing materials that can be produced in one piece of the desired length by means of rollform of 0.50 - 0.80 mm sheet metal and painted with electrostatic oven paint system.

Tile patterned sheet: It is produced as the same trapezoidal sheet, but the tile pattern on it gains the appearance of a metal tile as it is processed during printing through rollform.

Sandwich panel: This material consists of pressing polyurethane foam or glass wool between two sheets of 0.50 - 0.80 mm and the material thicknesses change according to the desired system.

Shingling: This system consists of 3 stages. First, the plates called "OSB" are laid on the roof, then a pitched membrane is laid on it and it is burned by shaking, and finally the material called shingles is nailed with a special nail, thus the system is completed.

These materials, which we have briefly mentioned, are generally actively used in prefabricated buildings and are in demand according to their place of use, price and aesthetics. In our next articles, we will discuss the advantages and disadvantages of these materials and try to provide sectoral advice.
