Air Vent


Why Ventilate?
 
Attic ventilation might seem like a minor consideration, but when properly installed, it can extend the life of your attic and roof structure -- saving you hundreds of dollars in repair costs.

During warmer months, ventilation helps keep attics cool. It helps prevent hot, moist summer air from warping the roof sheathing. It also stops shingles from deteriorating prematurely. What's more, fresh air in the attic makes a home much easier to cool, which can result in lower energy costs.

In winter months, ventilation helps reduce moisture to keep attics dry. It stops water from backing up under shingles, damaging insulation, and rotting the roof structure itself.  It also helps prevent ice dams from forming. Ice dams occur in areas where snowfall and cold temperatures are common and pose a special problem because they prevent melt water from running off the roof. They can even cause leaks inside your home, resulting in drywall damage. 
Air Vent’s new The Edge™ Vent provides proper intake ventilation for homes with little or no overhang. It’s a roof-top installed, shingle-over intake vent designed based on roofing contractor feedback from their Ask the Expert™ seminars. It can be used to supplement existing soffit or undereave vents as well.  The Edge Vent provides 9 square inches of net free area per linear foot to balance with ShingleVent® II ridge vents and other Air Vent exhaust vents.
