Your roof can fail even if the shingles still look good and poor ventilation is one of the biggest reasons why.
Proper attic ventilation helps remove trapped heat and moisture from your home. Without it excessive heat can shorten the life of your shingles, increase energy costs, cause mold growth, and even lead to ice dams during Maine winters.
Signs of poor roof ventilation can include: Hot upstairs rooms, Mold or moisture in the attic, Premature shingle aging, Ice buildup at the roof edge, High energy bills.
At B’s Roofing & Construction LLC, we inspect the entire roofing system not just the shingles. Proper intake and exhaust ventilation can make a major difference in the lifespan of your roof.
