Why it's important to ventilate your attic: Roofs at risk. Normal household activities can wreak havoc on an attic and, ultimately, a roof. Activities like showers, laundry, dishwashing, cooking and more, all generate moisture that can damage insulation, rafters, wood deck, underlayment and shingles during winter. During the summer, heat buildup in the attic can cause premature aging and cracking of wood and roofing materials -- all of which could compromise the performance of your roof. For maximum roof protection, either new or replacement, a well-ventilated attic is key. And Owens Cornings VentSure® system is the solution. Here's how a VentSure® ridge vent works. Balanced air flow keeps attic temperatures from reaching extremes of temperature or humidity. Undereave soffit vents allow outside air to flow up and into the attic. RAFT-R-MATE® vents channel air past attic insulation up the roof slope to the roof peak and out the VentSure® ridge vent. The result is a cooler, drier attic. And that can mean a longer-lasting roof. The Owens Corning VentSure® system works year-round for proper ventilation without moving parts or energy consumption. Balance is important. A ventilation system must be balanced for uniform, continuous air flow. In a balanced ventilation system, the amount of net free area (open space through which ventilation takes place) at the eaves is equal to the amount of net free area at the ridge of the roof. To achieve this, you must combine VentSure® ridge vents with undereave louvered or soffit vents. RAFT-R-MATE® vents inside your attic keep insulation from blocking airflow to the roof peak within the attic. When a ventilation system is balanced, wind blowing over the ridge creates a negative pressure area that draws the warmer air out of the attic. Replacement air enters through the undereave vents, bathes the underside of the roof, and exhausts at the ridge cap. Even when there is no wind, the natural convection action of rising warm air maintains a continuous air flow along the underside of the roof. |
