| Why Should you Ridge Vent? |
| |
| Did you know a well-ventilated attic is key to maximum roof protection? |
| In winter, normal household activities like doing laundry, running dishwashers and taking showers generate moisture that can damage insulation, rafters, wood deck, underlayment and shingles. In summer, heat build-up can cause premature aging and cracking of wood and roofing materials. |
| The only way to combat these problems is with balanced ventilation. When a ventilation system is balanced, wind blowing over the ridge creates a negative pressure that draws the warmer air out of the attic. Replacement air enters through the undereave vents, bathes the underside of the roof, and exits at the ridge cap. |
 |
| Even with no wind, the natural convection action of rising warm air maintains a continuous air flow along the underside of the roof. It's 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.
