The water-tightness of the roofing system is closely linked both to the inclination and to the length of the flaps. Before starting with the installation, it is advisable to check that the inclination corresponds to the indications shown in the table below. It is always useful to refer to the advice of professionals regarding the limits imposed by the local atmospheric conditions. In general, for slopes below 35% and / or for slopes of more than 5 meters in length and / or in areas with strong winds, it is advisable to design the roof equipped with ventilation and equipped with a micro-perforated waterproof membrane.
