A Roof louver is a covered opening that allow air to escape the attic. Several of these vents are usually required to properly ventilate the attic. They should be placed evenly across the roof.

According to federal guidelines, homes require 1 square foot of net free area (the total unobstructed area through which air can enter or exhaust a non-powered vent) for every 150 square feet of attic floor space. If balanced between intake and exhaust vents, the requirement is 1 square foot of net free area for every 300 square feet of attic floor space.
