If you live in the Northeast, you can’t help but admire the majestic, frozen beauty of the winter season. But some of nature’s decorative elements--including the sparkling icicles that hang from many homes and buildings--are a sign of problems to come. 

Damaging Ice Dams

When icicles form on your roof, chances are, ice dams are also building up. An ice dam is a thick ridge of ice that builds up on the eaves of your roof. They form when changing temperatures cause snow to accumulate, melt, and freeze. Water that backs up behind the ice dam can get into your home, damaging your insulation, ceilings, walls, floors, and more. The resulting mold, mildew, and rot can jeopardize the health of you and your family. 

How Ice Dams Form

Ice dams develop when an attic roof gets warm enough to melt the underside of a layer of snow. The water trickles down between the layers of snow and shingles and collects at the edge of the roof. Over time, layers of water continue to freeze and build up.

Preventing Ice Dams

The best way to prevent ice dam buildup is to properly insulate and ventilate your home. If you have icicles forming on edge of your roof, contact the pros at Cormack Construction. We’ll come out and check out your attic insulation, access doors, and hatches. In addition, we’ll make sure your kitchen and bathroom exhausts are working properly. We’ll also check for other possible causes of heat loss, including issues with your chimney and openings for electrical cables and vent pipes.
