Answer: ventilation of a roof is mandatory to protect the entire roof from heat, frost or rain.

Ventilation makes it possible to permanently preserve the solidity of a roof. Thanks to this device, heat, cold or rain do much less harm to the frame, the roofing, the insulation or the roofing screen. The installation of the ventilation of the roof is done between the sub-roof and the sub-roof screen. To obtain satisfactory ventilation, create air inlets and outlets of equal size and staggered. The air inlets are located at the bottom of the gutters. In contrast, the air outlets are located at the ridge. Finally, cat flaps, ventilation tiles, must be installed. Self-ventilated tiles, which do not require the installation of additional systems, are also possible to allow proper ventilation of the roof. You too, send us your DIY question.
