During the long winter months, snow and ice may be inevitable. But if you see icicles hanging from the edge of your roof, it may be a sign of an ice dam.
An ice dam is a ridge of ice that forms along the edge of your roof. This happens when warm air inside your home melts snow on the roof, which then refreezes as it reaches the unheated colder eaves when temperatures drop.
The problem is, these ice dams can force water up under your roof's shingles. And this may cause water to leak into your attic, ceiling or wall, soaking your insulation, drywall and paint. Ice dams can also damage your roof and gutters.
The best thing you can do is to take steps to help prevent future ice dams from forming. You can start by removing or relocating heat sources, such as lights, from attic areas.
You also may want to make sure your attic is well-ventilated. Venting the warm air out of the attic can help keep the inside temperatures cooler, which may help break the cycle of melting and refreezing ice and snow on the roof.
Another thing to check? Be sure that any exhaust ducts from bathrooms or kitchens are venting to the outside, rather than into your attic.
You can also add insulation to your attic floor to help keep heat out of the attic.
Another tip? Insulate the access doors to your attic.
Lastly, have a professional check the flashing around your chimney. If the flashing is cracked, it may allow hot air to escape and water to seep in. Have a pro make repairs as necessary.
By taking these steps, you can help prevent ice dams from forming. Then you'll be able to enjoy the winter months, with some peace of mind.
