Do roof turbine vents work?

Highly Effective. In low wind situations, turbine vents do an admirable job of moving warm air out of the attic areas of a property. However, when the wind is blowing, these vents turn into a powerful vacuum of warm air, drawing it up through the vent as effectively as any powered alternative.

Should you cover turbine roof vents in winter?

You should absolutely leave your roof vents open during the winter – do not cover them! During the winter, roof ventilation works to keep temperatures even. Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.

Are roof vents better than turbines?

Still, despite running the entire length of your roof, ridge vents are static and won’t move air the same way turbines do. As long as there’s a healthy amount of wind to power them, turbine vents will provide superior ventilation for your attic.

Do whirlybirds make your house colder in winter?
