Preventing ice dams on your roof

Ice dams on the roof can cause water leaks, damage shingles, and affect a home's energy efficiency. Fortunately, there are simple solutions to prevent them.

Here's how to limit the formation of ice dams:

• Ensure good attic insulation — insufficient insulation creates a build-up of heat under the roof.

• Check roof ventilation — soffits and air intakes must be clear to allow constant airflow.

• Clean gutters before winter — clogged gutters promote ice buildup.

• Eliminate heat sources under the roof — bathroom ducts or poorly directed fans increase the attic temperature.

• Intervene at the first signs — stalactites, overflowing gutters or irregular melting indicate a problem.
