We experienced ice damming this winter. Ice dams form when snow melts on your roof until it meets the unheated bottom edge of the roof and then freezes. Any additional melted snow or water will not properly drain off the roof and can cause many issues to your home.
Ice damming can cause water leak(s) into your home. This leak can cause damage to walls, ceilings, insulation and other areas.
This is a example of ice damming on a house we responded to this past winter.
