The area to be installed in roof SPP systems and the area structure have critical importance in the construction selection. A suitable construction structure should be selected by examining the roof structure to be installed. In the installation of roof SPP systems, the structure of the roof determines the construction structure to be used. The construction structure differs according to the roof structure. The main reason for this is that the system to be installed will have a long life, operate at optimum efficiency and prevent negativities.

The construction structure to be used in flat roof GES projects is determined by making load and seismic calculations. The most accurate production is carried out by considering the load, slope and environmental conditions that the construction structure will carry.
