The answer to 'roof maintenance ice dam' is that ice dams are a common issue that can cause significant damage to a home's roof and interior. Ice dams form when snow on the roof melts, often due to poor insulation or ventilation, and then refreezes at the roof's edge, creating a barrier that prevents water from draining properly. This can lead to water leaks, drywall and ceiling damage, and even structural issues.
To prevent and address ice dams, homeowners should ensure their roof is properly insulated and ventilated, clear snow from the roof, and consider installing heat cables or other de-icing systems. If ice dams have already formed, it's best to call a professional roofing contractor to safely remove the ice and assess any damage.
