Best roofing contractors in Ontario

★★★★★5 (361 reviews)score 95/100

A five-person crew led by Marcel, with Dorian and Eron frequently named, digs past the obvious job to catch rotted beams, missing insulation, and poor slopes before they become bigger problems. Work spans aluminum and vinyl siding, eavestroughs, soffit, fascia, and flashing, with cleanup precise enough that neighbours notice. Pricing sits above the cheapest bids in the GTHA, but reviewers say the extra cost buys real foresight.

• Named crew (Dorian, Marcel, Eron) with consistent recognition across jobs
• Finds and fixes hidden structural issues without extra upselling
• Meticulous daily cleanup and respect for landscaping
• Handles the full exterior package: siding, eavestroughs, soffit, fascia, flashing

Watch out: Pricing runs above budget competitors, though reviewers say the thoroughness justifies it.
