The answer to 'flat roof ice dams' is that ice dams form when snow on a flat roof melts and refreezes at the roof's edge, creating a barrier that prevents proper drainage. This can lead to water buildup, leaks, and potential damage to the roof and building interior.
Common causes of flat roof ice dams include poor insulation, inadequate ventilation, and heavy snow accumulation. Symptoms include icicles forming along the roof's edge, standing water on the roof, and leaks inside the home. Solutions may involve improving insulation, adding ventilation, and carefully removing snow and ice buildup to prevent further issues.
