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.
No turbines on roof.
In addition pay attention to the maximum roof pitch that will work with the turbines.
It s a measure of how much power the turbine will generate at the highest wind speed that the turbine can tolerate.
No additional source of power is needed and turbines are available in a wide variety of sizes and styles.
The turbines are adjustable so that the spinning part is level even though the roof is slanted.
Turbine vents do indeed look like small wind turbines installed on your roof.
These will not rust.
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.

If you decide to add more turbine vents to your roof be sure to buy ones that are aluminum.
Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.
As the wind moves across your rooftop it turns these turbines and draws air up out of your attic area.
But the fact is neither of those conditions are likely to occur on a rooftop.
