The answer to 'architectural shingles ice dam' is that ice dams can form on homes with architectural shingles, causing water damage and leaks. Ice dams occur when snow on the roof melts, often due to heat loss from the home, and then refreezes at the roof's edge, creating a dam that prevents proper drainage. This can lead to water backing up under the shingles and into the home.
Common causes of ice dams on architectural shingles include insufficient attic insulation, poor ventilation, and heat loss from the home. Symptoms include icicles forming at the roof's edge, water stains on interior walls and ceilings, and potential damage to the shingles and roof structure. Solutions can include improving insulation and ventilation, installing heat cables, or removing the ice dam manually. Homeowners may be able to address minor ice dams themselves, but larger issues or damage may require the expertise of a professional roofing contractor.
