The answer is yes they really do.
How do roof turbines work.
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.
Rust can be a problem with some turbines.
A turbine has a series of vanes that spin as wind passes through them.
How much air must be moved.
A simple application of wd 40 should do the job.
Because warm air rises up the wind powered vents with their spinning action tend to suck the air outside.
If you re shopping for roof turbines look for models with enclosed self lubricating bearings.
Since turbines are attached directly to attic spaces they can siphon away that moist air effectively.
These are very common to see on older roofs.
Some turbines have ball bearings that need occasional lubrication.
Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing.
A turbine vents spins with the slightest breeze.
A turbine has a series of vanes that spin as wind passes through them.
Do roof turbines require maintenance.
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.
Unlike turbines this venting style does not have any moving parts.
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.
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.
As soon as it starts to spin it vacuums air out of your attic.
The popular ridge and soffit ventilation systems and the traditional metal pot vents are also passive ventilation systems.
It could be dormers gable end vents ridge vents turtle vents or turbines vents.
Turbines work for free.
A ridge vent runs across the top of the roof s peak.
A ridge vent runs across the top of the roof s peak unlike turbines this venting style does not have any moving parts.
Aluminum models are largely rust and tarnish.
These all work well and are typically installed near the top or the peak of the roof called the ridge.
They come in different colors.
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.
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.
But the question our customers often ask is do they really work.
Most residential homes have some type of attic ventilation.
