Vents that run along the roof ridge are an alternative to those that exit through the roof decking or gables and if the ridge is long enough they may be the only roof vents you need. The ridge is always in a depressurized area of the house because the wind hits that and sort of bounces off the roof and goes in a circular motion which causes a draw at the ridge.
