They are also made of metal which is likely to rust whereas ridge vents don’t have any such issues. Roof turbines require more maintenance than ridge ventsĪs you know roof turbines have moving parts. Since ridge vents run along the full length of the ridges it takes a lot more time and effort than the installation of a wind turbine where you need to remove only a few shingles. Not only roof turbines require a small area for installation they are also cheaper to install when compared to ridge vents.

Roof turbines need only a smaller area for their installation when compared to ridge vents. Roof turbines require only a small area for installation and they cost less A wind blowing over the ridge vent can create a low pressure on the leeward side accelerating air removal but the volume of air moved even then is not as much as that of a wind turbine. Since ridge vents depend on the convection of heat they almost always move the same amount of air out. The more the wind the more powerful will be its venting. A turbine vent will rotate at even a small wind which sucks out the air from the attic. Under the right conditions, a whirlybird can move considerably more air than a ridge vent. Roof turbines move more air than ridge vents To be honest, they are hideous to look at compared to the more sophisticated ridge vents. From a distance, they look like large mushrooms sprouted on the roof. In contrast, you can spot a whirlybird from a mile away. A typical ridge vent has a height of only one inch or less and it cannot be seen from the outside. Ridge vents are very shallow even though they run the whole length of the ridge. Ridge vents complement the roof while turbine vents do not This is because once the hot air is exhausted from the attic the lack of air there needs to be filled with the cool air from the outside, and soffit vents are the best choice for this.

This is because when the wind flows, it moves the fins of the turbine vent making it work as an active ventilator. Roof turbines remove air by active ventilation while ridge vents do that by passive ventilationĮven though roof turbines do not consume any energy they remove air just like active ventilators. One the other hand, ridge vents are static vents, they do not move. It is this movement that helps the turbines to suck the air out of the attic. They have a fan-like structure that moves with the wind. Roof turbines have moving parts while ridge vents don’tĪs you know whirlybirds are turbines on the roof that rotate. Let’s see in detail the similarities and differences between whirlybird roof turbines and ridge vents. Roof turbines are those spinning things you see on the roof of houses and commercial spaces whereas ridge vents are shallow vents running along the ridge of the roof.
