In a balanced system, wind blowing over the ridge creates a negative pressure that draws the warmer air out of the attic. Replacement air enters through the undereave or soffit vents, bathes the underside of the roof, and exits at the ridge cap through ridge vents, roof vents or gable vents. Even with no wind, the natural convection action of rising warm air maintains a continuous airflow along the underside of the roof. Its a system that works year round with no moving parts or energy consumption.
The Benefits of Roof Ventilation
|Allows outside air to flow naturally upward and out of attic.|
|Promotes a cooler, drier attic.|
Helps prevent moisture from becoming trapped in insulation, structural wood, shingles and roof deck.
|Helps prevent rotting, mildew, drywall damage, peeling paint and warped siding.|
|Provides year-round performance for consistent ventilation without energy consumption.|
