Ice Dams

8/1/2019 (Permalink)

Ice dams when snow melts.  The water runs down your roof and refreezes forming icicles. This only occurs when part of your roof warms to above 32 degrees F, warm enough to melt the snow, while the roof edge remains below freezing. When snow builds up on the roof the heat from inside the house will warm and melt the snow which runs down the roof side and refreezes. 

The water pools up and freezes back up under the shingles.  In some cases it can go mas high as 6 to 10 feet up the roof. Later as it melts, it drips through the roof and into your walls or worst yet your ceiling. 

Damage can be serious; Can cause peeling paint, rot, mold and more. The problem is most common after a heavy snow.
