Protecting Your Roof Through a Quebec Winter

The Quebec winter is the ultimate test for a roof. Freeze-thaw cycles, heavy snow, and ice dams put even the best roofs under serious stress. Here is how to reduce the risks.

Understanding Ice Dams

An ice dam forms when heat escaping from the house melts the snow on the roof; the water runs toward the cold eave, freezes, and builds up a ridge. Water trapped behind the dam can then seep under the shingles. This is one of the most common causes of winter water infiltration.

Ventilation: Your Best Defence

Good attic ventilation keeps the roof cold and even, which prevents snow from melting unevenly. Combined with proper insulation, it is the best defence against ice dams — far more effective than chipping away at ice every winter.

What to Watch For and When to Call

Watch for large ice build-ups along the eaves, significant icicles, and water stains inside the home. If you notice a leak, don't wait: our emergency service is available 24/7 to stabilize the situation before the damage worsens.
