The protection you get from your roofing system is important all year round, no matter where you live. Your insulation below that roofing is key to extending the longevity of those shingles. Adding insulation before, after, or in between roofing upgrades can be key to not only saving money on your energy costs, but making sure your roofing system performs correctly.
Insufficient insulation can cause a multitude of issues. The most obvious ones involve high costs of losing heat or cool air through the attic when trying to keep your home at a comfortable temperature. The less known issues that can arise from insulation issues can cause damage to the home that can lead to even higher costs.
Without the proper insulation in the winter your home becomes more prone to ice damming. Caused by the melting and refreezing of ice or snow on the roof, ice damming can cause major issues inside the home, including the intrusion of water. Drywall, flooring and paint can be quickly damaged in a situation that can be left unfixed until all the snow and ice has melted. Simply making sure all areas of the attic are properly insulated can help prevent these ice dams from ever happening.
