An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas. Repairs for roof damage, interior water leaks, damage to walls and insulation, floors, window casings, and removal of icedams and snow that caused these and other damages will be covered by your homeowners insurance policy, subject of course to a deductible.
