As severe winter weather arrives, so do property damage risks as a result of ice dams. In fact, ice dams during freezing temperatures can cause thousands of dollars in property damage, according to the Insurance Institute for Business & Home Safety (IBHS).
During freezing weather, heat from your home or business can escape through the roof and melt snow on the roof. The snow melt can trickle down to the roof’s edge and refreeze, creating an ice dam that leaves additional snow melt no place to go but inside the attic.
