DAMAGE TO SHINGLES AND ROOFING MATERIALS

Too much moisture in your attic can cause a lot of damage to your roof. Rust may form on your roof nails and venting duct straps. Unsightly mold, algae, or fungus may appear on your roofing materials. Your roof can decay because of moisture in your attic.

UNCOMFORTABLE INDOOR TEMPERATURES

When poor ventilation causes hot air to build up in your attic, it can flow into your living space, making your home uncomfortably warm. When hot air builds up in your attic during the summer, its temperature can climb to over 150 degrees. The hot air then passes through your attic floor into your home. This results in increased energy bills, an overworked air conditioning system, and an uncomfortable indoor atmosphere in your home.

DAMPNESS IN YOUR ATTIC

When roof ventilation doesn’t work correctly, moisture from rising warm air condenses on your rafters. Dampness in your attic is a clear sign you have problems with the roof ventilation.

ICE DAMS

Attic ventilation systems should bring attic temperatures as close to outdoor air temperatures. In the wintertime, cool air enters the attic through intake vents above the eaves and helps prevent ice damming. Ice dams develop when snow melts and then refreezes at the edges of your roof. This refreezing is because of the buildup of heat in your attic space. Ice dams can cause extensive damage. They may cause damage to your walls, ceiling, and insulation.
