Roofing & Insulation in Southern Ontario: Defend Against Snow, Wind & Ice Dams

Your roof is your home's first line of defense against Ontario's unpredictable climate. Between torrential spring rains, intense summer sun, and brutal winter blizzard cycles, a compromised roofing system can quickly lead to severe structural rot, insulation degradation, and hazardous mold growth.

What Causes Destructive Ice Dams?

Ice dams form when heat escapes from living spaces into unconditioned attic spaces due to inadequate insulation (low R-value) and poor soffit ventilation. The snow on the upper roof melts, runs down to the cold roof eaves, and freezes into a solid ice dam. Trapped meltwater backs up under the shingles and leaks directly into ceilings and walls.
