What affects roof replacement cost in Ontario

Roof Replacement costs in Ontario differ from the national baseline mainly because of local labor rates. Roofing labor in Ontario runs about 6% below the national average roofer wage (Job Bank, NOC 73110), modestly holding installation cost down. The Great Lakes snowbelts from Barrie to the Bruce Peninsula bury roofs in lake-effect snow that repeatedly melts and refreezes at the eaves; ice-and-water shield extended well past the exterior wall line plus balanced soffit-to-ridge ventilation are the standard remedy against the ice dams this snowbelt produces. Most Ontario municipalities require a building permit for residential roof replacement pulled by the contractor; typical residential fees run $150–$400, usually with a final inspection. Ontario applies 13% Harmonized Sales Tax (HST) to roofing materials.
