Icicles and ice dams may cause severe damage to your roof, gutters and interior of your home.
In the Twin Cities area, winter weather can put your roof through a beating. Wind, rain, ice and snow can be a relentless enemy to your roof and home exterior. However, those pretty icicles and benign-looking ice mounds — or ice dams — on the gutters and eaves are one of the most damaging issues of the winter season.
Ice dams are caused by temperature differences between the roof surface above attics, living spaces and the eaves of your home. The reason roofs have warm and cool spots is due to heat escaping the living spaces into the attic. If the attic is in fact warmer than outdoor conditions, the roof above the attic will be warmer than the eaves.
Now, when the warmer section of the roof melts snow and ice, the water flows down to the cooler eaves and gutters where it re-freezes. This cycle often repeats itself again and again. Melting snow and ice reach the eaves and ice accumulates into “ice dams”. The result is potential damage to roofing materials, the gutter and water penetration into the attic, ceiling and walls of your home.
Preventing Ice Dams
The key to preventing ice dams is making sure your roof is a roofing system rather than a shingle. Your roof needs more than a shingle to prevent ice dams. It needs proper ventilation and insulation to complete your roofing system.
If you keep your eaves or roof’s edge and gutters free of snow and ice, a few inches at most, you typically won’t deal with ice dams. The more pressing and dangerous issue is when ice dams develop on higher areas of your roof where you can not reach the snow to remove it.
This is when you should call the professionals at Younger Exteriors to safely remove the ice dam and exercise preventive measures.
