Roof ventilators are a type of exhaust vent that removes heat and stale air from inside attic space. The best commercial roof vents have rugged construction and are weather resistant. When correctly installed, these vents circulate air, cool temperatures inside attics, prevent heat and moisture buildup and reduce the strain on your air conditioning system.
Commercial roof vents exhaust hot and contaminated air away from the roof and make indoor air healthier and fresher. Also, because the AC does not run as long, you will see a decrease in energy consumption and, as a result, the monthly utility bill. Before buying, it is essential to compare different roof ventilator types. That way, you will select the right one based on your industry and application.
Roof Exhaust Vent Types
- Box Vents – Box vents, which also go by the names of Flat Vents, Low Profile Vents, Turtle Vents, and Louvers, are static, meaning there are no moving parts. These vents get installed over a hole cut in the roof. With natural convection, the vents provide an opening for hot, rising air to escape. For the best results, the installer will place Box Vents as close to the ridge of the roof as possible.
- Ridge Vents – These vents are also static. For these, a raised center goes over the ridge. The most efficient system among the different options is a soffit. Just make sure the installer runs this the entire length of the roof, not only for cosmetic purposes but to also prevent some sections from aging faster than others.
- Wind Turbines – As a non-static product, wind turbines have moving parts. Instead of relying on motor power, the wind rotates the turbine. When the wind blows, these vents move more air compared to Box Vents. To prevent a squeaking noise as the turbine moves, choose vents with permanently lubricated ball bearings and plastic bushings.
- Power Vents – You can mount these vents on the roof or gable. Depending on the style you select, some have an adjustable thermostat or humidistat that kicks the unit on whenever the temperature or humidity level in the attic space reaches a certain point. You can choose between vents that get hardwired into your home’s electricity or those that run on solar power.
- Soffit Vents – Installed in soffits and eaves, this is one of the favorite roof exhaust vent types. Ultimately, these vents increase airflow.
