Attic Turbine Ventilator Maintenance Basics

A turbine vent on a flat, back roof.

Attic turbine ventilators are also known as unpowered ventilators. They require only the wind to run. Homes with attic turbine ventilators benefit from improved air circulation.

They can also reduce energy consumption. With a turbine vent, the air conditioning system does not need to work as hard to cool the house. With that in mind, it's important to keep your turbine vent functioning at its highest level by performing regular maintenance.

Making Your Attic Turbine Ventilator Run Efficiently

The presence of wind where the ventilator is installed makes it rotate, pumping out hot air from the attic. Make sure the trees surrounding the house are cut or trimmed so they don't obstruct air flow to the turbine. Also, the higher the ventilator is on the roof, the more effectively it will be able to make use of the wind.

If there is wind, but the ventilator is not rotating, it might be jammed by leaves, sticks, or even a bird. Cleaning and wiping out the dust and dirt regularly also helps keep the ventilator running at peak efficiency. Without regular cleaning, it could end up spinning abnormally or not at all.

If it is rotating in an abnormal way, rough or shaky, check the lubrication of the bearings. Add lubricants if needed. This will also eliminate annoying squeaking sounds. Also, check if the device is properly secured on the roof by inspecting the clamps or rivets that hold it. Sometimes they become loose due to natural elements and the passage of time.

What About During Winter?

During winter, heated air from within the house can be sucked out by the ventilator. To save energy, cover the ventilator with something plastic. Even if the ventilator is rotating, the plastic cover will block the warm air and keep it from escaping.

After a heavy snowfall, remove the snow build-up on the ventilator area. This will alleviate the pressure on the ventilator from carrying all that snow. It's also important to clear the snow because, if left too long, it can rust the blades.

Choosing the Proper Material

When choosing your attic turbine ventilator, consider a plastic or rust-proof aluminum ventilator as opposed to a steel ventilator. Plastic and aluminum materials last longer than steel, which is prone to deterioration due to rust. Plastics may eventually become brittle as well, so aluminum may be your best pick.


Adding an attic turbine ventilator is a great way to keep your house cool in the summer, but you can't forget all about it once it's installed. You have to check on it from time to time to keep its turning and spinning the way it should.
