​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 home and cause damage to walls, ceilings, insulation, and other areas.

 ICE DAMS

 REMEDIES:

​                    1) Add venting such as roof and soffit vents to allow air to flow over the insulation.

                     2) Install a hatch cover.

​                     3) Exhaust all ducts to outside.

​                     4) Increase R-value by adding more insulation.

​                     5) Install sealed (recessed) can lighting.

​                     6) Seal around chimney, all chases in the attic and all air penetrations such as pipes,

​                          plumbing vents and wire holes.
