Many parts of the country have experienced record snowfall amounts and
extreme cold temperatures this winter.
It is during this time of year that freezing temperatures can allow a
ridge of ice to form on the edge of a roof.
This is known as an ice dam and when they occur they can allow water to
back up behind it and leak into a home or building. The end result is water damage that is
frequently followed by mold growth.
According to the U.S. Government’s Energy Star Program website, “Ice dams
usually occur after a heavy snowfall and several days of freezing temperatures.
Warm air inside your home leaks into the attic and will warm the underside of
the roof causing snow and ice on the roof to melt. The melted water will drain
along the roof, under the snow, until it reaches the cold overhang. The
overhang tends to be at the same temperature as the outdoors and the melted
water will refreeze and form an ice dam and icicles. The ice dam can cause
damage to the roof, which will result in water leaks to the inside. Frequently
the result will be a water spot on the ceiling under the roof damage.”
Fortunately, ice dams can often be prevented by controlling heat loss from
the building into the attic. To keep
warm and moist air from entering the attic space from the interior of the
building, any air leakage pathways should be sealed and the attic needs to be
properly insulated. Proper attic ventilation will also help to keep a uniform
roof temperature. Vented appliances should be exhausted to outside of the
building and not into the attic and gutters need to be clean and operational to
allow water to properly drain off the roof.
If an ice dam does occur, it can cause water to quickly leak into a
building resulting in staining, water damage and mold growth. It can cause
considerable damage and mold growth that can impact the building’s indoor air
quality. Often the mold growth can be out of sight, but even mold
growing above ceilings and in wall cavities can create health concerns. For those who have damage due to an ice dam,

settlement for their property claim so their residential or commercial property
can be properly repaired.
