Here are three of the top benefits of good attic insulation for a roofing system. 1. Longer Shingle Lifespan A roof that’s too hot will cause asphalt shingles to expand and contract more frequently, making them more prone to splitting. This is dangerous because water could penetrate the material through these splits, exposing the inner roofing components to moisture. When this happens, roofing contractors might recommend the early replacement of your shingles. If your attic is properly insulated, you can have peace of mind that your roof will last longer. 2. Ice Dam Prevention Ice dams happen because of uneven temperature on the roof surface. When heat builds up in your attic, the section of the roof above your attic becomes warmer, causing the snow to melt. The snowmelt then travels toward the edge of the roof where the temperature is colder, thus causing the water to refreeze. This then results in the ice dams you see along the gutter. Proper attic insulation ensures an even temperature throughout your roofing, preventing the formation of ice dams during winter. If the ice dams on your roof have become too large, call a roof repair expert for advice. 3. Protection Against Roof Damage Improper insulation can lead to excessive humidity in the attic, which could further result in roofing problems. By insulating your attic, you can protect vital roofing components from mold, rot and other types of damage that will compromise the structural integrity of your roof.
