What Is an Ice Dam?
An ice dam is a buildup of ice on the roof. You may see this buildup on the edge of the roof, but these dams can occur at many different places on your roof. The ice is really not the issue, but it’s the dam effect. Your roof is designed to be effective at shedding water. The ice dam prevents water from draining. It pools up behind the ice, and seeps under the shingles during a Massachusetts winter. This damages the wood under the shingles, the wiring, dry wall, exterior siding and insulation.
Ice dams typically occur when heavy snow falls, then we get freezing temperatures. Your roof might warm up enough to melt the snow. That water trickles down to another part of your roof where it freezes. Over time, it creates the ice dam.
Three Ways to Prevent Ice Dams
You can’t control the weather, but you can control the systems of your home. Here are three key ways to prevent ice dams:
- Increase attic insulation to prevent warm spots on the roof
- Increase the attic ventilation, adding intake and exhaust vents to prevent the roof from being warmed by air
- Re-roofing to include a waterproof sealing sheet under the shingles in your Massachusetts home.
If your home gets ice dams during the winter, you should have it inspected to determine how to prevent the ice from damaging it even further.
