Flat Roof Vent Installation: Mistakes to Avoid

When a flat roof is installed it requires a special flat roof vent, ideally these roofs are installed in regions with lower waterfall. Moisture build up can be a problem if the roofing material used to cover the roof, does not allow for water runoff. A flat roof does not allow for the best escape of heated air. The build up of high temperatures can cause trusses to expand eventually, resulting in cracks in the walls. Here are a few mistakes to avoid and suggestions to consider with a flat roof vent installation.

Use the Right Vent

All vents can be used with a slopped roof; a flat roof, however, presents different ventilation requirements. There are only three types of vents that work will flat roof construction. Avoid using a vent not specifically designed for a flat roof.

1. Mushroom Vent

A mushroom vent is the best alternative. Avoid placing the vent where you have to cut a joist.

2. Turbine Vents

These vents are best installed during roof construction. The roof and shingles need to be cut and sealed completely to avoid leaks.

3. Gable Vents

A gable vent is a good ventilation alternative for a flat roof. Make sure you place the gable as high as possible, this allows for maximum heat escape.
