Why Ventilate?

Attic ventilation might seem like a minor consideration, but properly installed, it can extend the life of your homes' attics and roof structures -- saving your homeowners hundreds of dollars in repair costs -- and saving you from expensive, time-consuming callbacks.

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 the home, resulting in drywall damage.
