Ridge Vent works on
the basis of several principles. Adequate soffit ventilation coupled with
ridge ventilation produces a pathway for a continuous airflow along the
entire underside of the roof deck. Airflow is maintained two ways. First,
hot air naturally rises and exits out the ridge vent, pulling in cool
air from below. Second, positive airflow across the ridge of the house
creates a "venturi effect", or a negative pressure, which pulls
air out of the ridge vent and brings in cool air from the soffits below.
In calm or windy weather, the entire attic is vented by a constant flow
of cooler, dryer outside air.
