The answer to 'flat roof ice dam' is that a flat roof ice dam is a buildup of ice that forms at the edge of a flat roof, preventing proper drainage and causing water to back up onto the roof. This can lead to leaks, structural damage, and other problems.
Common causes of flat roof ice dams include poor insulation, inadequate ventilation, and heavy snowfall. Symptoms include icicles forming at the roof's edge, water stains on the ceiling, and standing water on the roof. Solutions may include improving insulation, installing roof heating cables, or removing snow from the roof. However, some issues may require the expertise of a professional roofer, especially if the ice dam has already caused significant damage.
