What is an ice dam? 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 condominium and cause damage to walls, ceilings, insulation and other areas.
The water pools on the roof because the ice dam prevents it from rolling off the roof . . hence the term ‘dam’. It does not matter how new your roof is you can still take on water.
The best way to handle ice dams is to prevent them. There are companies that will remove ice dams and damage the roof at the same time . . . or not.
Removing the snow from the roof will stop new dams from forming.
It isn’t just the melting snow on the roof that causes ice dams. The University of Minnesota Extension website has some great information about what causes ice dams and how to prevent them.
