They are very flexible regarding placement, and there’s almost always room for them.
How well do 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.

Are turbine vents better than box vents?
Wind turbine vents are able to move more air than box vents are, but only when the wind is blowing.
