The roof consists not only of a covering. In addition to it, the budget will include components of the supporting structure, components for the drainage system, insulation and vapor barrier. Also do not forget about the cost of transport and the actual roofing. All materials must be correctly selected and delivered on time to the construction site. After that, you can proceed to installation.
Any roof needs a reliable frame on which the coating will be installed. When mounting a supporting structure, it is important to ensure its strength and resistance to external influences
When planning roofing, the installation of a drainage system cannot be ignored, since its absence significantly reduces the life of the roof. Modern drainage systems successfully fit into any project and can become an additional element of the exterior decoration of the building.
If the supporting structures are made of wood, it must be impregnated with protective compounds that will prevent fire, decay, parasite and mold damage. All heaters must also include flame retardant impregnations.
