A roof (all the roofs of a building) is a roof generally supported by a frame. The main properties sought for the roof are waterproofing, but also aesthetics, lightness, mechanical resistance and rainwater flow.

Determining the causes of infiltrations and / or malfunctions is also part of our skills.

If necessary, a survey can be carried out as well as the taking of samples (membrane, insulation, mold, etc.) which can be sent to a specialized laboratory for analysis.
