A turbine has a series of vanes that spin as wind passes through them.
How do roof turbines work.
Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing.
A turbine vent is a passive ventilation device.
These all work well and are typically installed near the top or the peak of the roof called the ridge.
Since turbines are attached directly to attic spaces they can siphon away that moist air effectively.
But the question our customers often ask is do they really work.
Turbine vents use a combination of wind and convection to extract stale hot air from inside your home and replace it with the cool clean air from the outside.
Unlike turbines this venting style does not have any moving parts.
They come in different colors.
A ridge vent runs across the top of the roof s peak.
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.
The faster the wind speed the faster the turbine rotates.

How much air must be moved.

How do turbine roof vents work.
If the wind is blowing and catches the fins then the turbines act like giant vacuum pumps sucking hundreds of cubic feet of hot air out of an attic per minute.
The popular ridge and soffit ventilation systems and the traditional metal pot vents are also passive ventilation systems.
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.
Aluminum models are largely rust and tarnish.
Because warm air rises up the wind powered vents with their spinning action tend to suck the air outside.
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.
A turbine vents spins with the slightest breeze.
Rust can be a problem with some turbines.
The answer is yes they really do.
Some turbines have ball bearings that need occasional lubrication.
