Static vents are basically a large hole in the roof with a covering on the top of them. They allow the air to naturally flow out of the top of the attic. The static vents are sometimes referred to as turtle vents. In order for the static vents to work properly, there must be sufficient soffit vents.
We want to have 60% of the ventilation in the soffits and 40% using the static vents at the top of the attic.
