No turbines on roof.
Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.
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.
First the rated power of a turbine is a best case scenario.
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.
As the wind moves across your rooftop it turns these turbines and draws air up out of your attic area.
Aluminum no rust.
These will not rust.
