Ice dam development happens more often on houses with inadequate or poorly installed attic or roof insulation and homes with poor attic ventilation. Q: Why do ice dams form?Ī: Ice dams can form on any type of roof when the roofing material is above freezing on part of the home and below freezing near its edges. When snow on a roof melts, the water that would normally fall off the roof and into the gutter or onto the ground freezes at the roof’s edge. It’s a dam made of ice, by the ice itself, that keeps water from flowing.
