Do You Have Ice Dams?

Here in the Maryland/Pennsylvania area, we are in the height of the season for winter precipitation of all forms including snow, sleet, freezing rain, and ice. With the recent snow event that brought with it sleet and freezing rain on top of it all, you may want to check your roof to see if ice dams are forming. Ice dams can be bad news for your roof, your home, and potentially your health!

What is an Ice Dam?
An ice dam is a ridge of ice that forms at the edge of a roof and holds back melting snow from draining properly.

Ice Dams Cause Problems!
Roofs are designed to quickly shed water, not hold water. Ice dams are problematic because they hold water on the roof surface for much longer periods of time than the roof is designed. This can force water to penetrate behind/under the roof covering materials and subsequently leak from the roof into the building envelope.
