The answer to 'shingle replacement ice dam' is that ice dams can cause significant damage to your roof and shingles, requiring professional repair or replacement. Ice dams form when snow on your roof melts and refreezes at the roof's edge, preventing proper drainage and leading to water buildup that can seep under shingles and into your home. Common causes include poor attic insulation, inadequate ventilation, and heavy snow accumulation.
Symptoms of an ice dam issue include water stains on ceilings and walls, icicles hanging from the roof, and visible ice buildup. While some minor ice dam removal may be a DIY task, extensive shingle damage or leaks often require a professional roofing contractor to properly assess the situation, make necessary repairs, and prevent future ice dam formation.
