How Does Vent-A-Roof Work?
Efficient ridge ventilation occurs when several components are in place. Fresh outside air flows through small intake vents installed within the soffit/eaves of the house. The cooler incoming air then rises from these intake points and mixes within the ceiling cavity and rises to the highest point of the roof. The mix of hot stale air and cool fresh air escapes through the Vent A Roof ridge ventilation system creating an environmentally friendly, fully ventilated ceiling cavity. Continuous airflow is created by a naturally occurring thermal effect.
Furthermore, positive airflow across the ridge of the house creates a negative pressure which pulls air out from the ridge vent system and brings in fresh air from the intake vents below. In either calm or windy conditions, the entire ceiling cavity is vented by a constant flow of cooler, dryer outside air. These key factors create and maintain effective and efficient air flow.
