Power roof vent vs turbine. Picture above shows both roof vents a rotary turbine vent on the left and an aura gravity ventilator on the right with curb mount flanges. A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic. A ridge vent runs across the top of the roof s peak. It is hard to tell if a house has the vents installed or not if you look from the ground up.

All aura gravity ventilators are made of rust free aluminum. Compared to turbine vents ridge ventilation blends very well with the design of your roof hence your home. Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents. Roof turbine s wear out lose their functionality.

A turbine has a series of vanes that spin as wind passes through them. A roof turbine can be made of galvanized steel that rusts as shown above.

Wind driven roof vents will pull more air from the attic but only when the wind is blowing. You should not mix active and passive ventilation systems. Most of the time this is not productive as a ridge vent will compete with a solar fan or a roof turbine will detract from a ridge vent. Two types of attic ventilation vents compared turbine vents roof with turbine attic vent.

Turbine vent two of the most popular styles. Your roof just doesn t work well without them. A ridge vent as the name indicates is located at the ridges where your roof peaks and runs along the top of those ridges.
