Problems to Avoid
If your attic is not properly ventilated, several problems can occur. In extreme climate months (summer and winter), the possessions in your attic may be at risk. Can you imagine what your photo album looks like when the temperature in your attic hits 160 degrees? In the winter, frost can form on the underside of your roof, causing condensation and eventual dripping, putting everything you own at risk, not to mention damage to your roof joists and floor boards. And though you’re not intentionally heating or cooling your attic, the hot and cold air that this space takes on will eventually seep over into the rest of your home’s interior, making your utility bills increase unless everything is correctly ventilated.
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 under eave 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 airflow 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
