The answer to 'flat roof ice dams' is that ice dams are a common problem on flat roofs during the winter months. Ice dams form when melting snow refreezes at the edge of the roof, creating a barrier that prevents further melting water from draining properly. This can lead to water backup, leaks, and potential damage to the roof and interior of the home.
The main causes of flat roof ice dams are poor insulation, inadequate ventilation, and heat loss from the home. When warm air from the home escapes through the roof, it melts the snow on the upper portions of the roof, which then refreezes at the colder roof edges. Symptoms of flat roof ice dams include icicles, ice buildup at the roof's edge, and water stains or leaks inside the home.
