Ice Dam Prevention you can actually trust
Ice dams form when warm attic air melts snow on the roof, then the meltwater refreezes at the cold eave. Fix the attic and you fix the dam. We add insulation to R-60, seal every attic bypass, verify soffit-to-ridge airflow, and — for roofs where geometry won't cooperate — install heat cables on eaves and valleys.
Every Oshawa technician is WETT SITE-Basic certified at minimum, with two inspectors carrying full SITE-Comprehensive credentials.

Ice Dam Prevention in Oshawa — common questions
Do heat cables actually work?+
Yes, but only as a targeted fix. The real solution is attic insulation and ventilation — cables are for stubborn dormer valleys and low-slope eaves that airflow can't reach.
What causes ice dams in Toronto?+
A warm attic. Heat leaks through the ceiling, melts snow on the shingle, meltwater runs to the cold overhang and freezes into a dam that backs water under the shingle.
