Roof structures must be protected from the weather effects.
A building should be built not only on solid ground, but also be optimally protected through a well-designed roof. Modern roof construction in combination with high-quality roofing materials are capable of permanently protecting the building interior against damage caused by bad weather of any kind.

Before the roof covering there should be sub-structure, which is normally of wood, but can also consist of a steel structure usually in industrial buildings, that has been pre-treated in a suitable manner. Efficient wood preservatives and effective corrosion inhibitors, coatings provide a long and lasting protection. Steel structures of industrial buildings are often covered with trapezoidal profiles.

In the construction of roofs attention should also be taken in the latitudes to allow a sufficient overhang of the roof. A sufficient roof overhang not only offers a high rain protection of masonry and facade, but also keeps hot sunlight from the building.

In addition, provision should be made in the planning of the roof space and enough space left for an optimal thermal insulation. In roof structures in old buildings, the energy efficiency can be greatly improved by insulation in the intermediate or below the rafters. A high energy efficiency occurs in roof construction where insulation of the rafters is choosen.

For flat roof designs, the selection of a suitable sealing material, such as bitumen, plastic or rubber sheets plays a crucial role. These sealing strips fulfill nearly all the requirements for a properly executed installation.
