If you decide to add more turbine vents to your roof be sure to buy ones that are aluminum.
No turbines on roof.
Step 3 clear any obstructions away from the turbines by pulling them free.
First the rated power of a turbine is a best case scenario.
As the wind moves across your rooftop it turns these turbines and draws air up out of your attic area.
It s a measure of how much power the turbine will generate at the highest wind speed that the turbine can tolerate.
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.
Examine the turbine from the exterior from the roof.
Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.
Aluminum no rust.
No additional source of power is needed and turbines are available in a wide variety of sizes and styles.

Turbine vents do indeed look like small wind turbines installed on your roof.
But the fact is neither of those conditions are likely to occur on a rooftop.
These will not rust.
