Install roof ventilation

In order to permanently preserve the solidity of a roof, ventilation is a must. This will prevent heat or rain from damaging the roof framing, roofing, insulation or screen.

Roof ventilation: air inlets and outlets

Installation of roof ventilation is possible thanks to the roof void in front of the roof screen. To obtain good ventilation, it will be necessary to create air inlets and outlets. These must be approximately equal so as not to generate pressure under the roof. The air inlets must be located at the bottom of the gutters. In contrast, the air outlets are placed in the upper part of the roof at the level of the ridge (which joins the two sides of the roof). Entrances and exits must be staggered. Once the air inlets and outlets have been made, install the cat flaps, which are ventilation tiles.

Self-ventilated tiles: autonomous ventilation

For ventilation of the roof, it is also possible to obtain self-ventilated tiles. With rounded shapes, they do not require any other ventilation system and are self-sufficient. This solution is therefore simple and effective, even if this type of roofing is more expensive in general than conventional tiles with an additional ventilation installation.
