Purpose of roof turbine vents.

A turbine vents spins with the slightest breeze. Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing. During the cold seasons vents help in dispersing moisture that may otherwise cause molds. While this also works in a ridge vent it is quite useful in turbines as they are attached to the roof making the dispersion a lot faster.

Roof vents need to move hot humid air from the attic to the outdoors so that humidity doesn t build up and cause mold rot or other moisture problems that findlay roofing regularly sees when dealing with attic issues. The downside to turbine vents is that they don t provide much venting power on calm days. They are easily installed. A turbine vent is a passive ventilation device.

Mother nature blows across the fins in the roof turbine vents as they exhaust the heat build up in the attic. Turbine vents can replace the hot air in your attic in minutes. Since turbines are attached directly to attic spaces they can siphon away that moist air effectively. All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows.
