Metal roofing has moved well past the barn-and-warehouse stigma in Toronto. Standing seam panels, steel shingles cut to look like slate or cedar shake, and exposed-fastener systems now show up on century homes in Leslieville, infill builds in North York, and cottages-turned-permanent-homes up in the Kawarthas commuter belt. We've collected 39 contractors in the city who install or repair metal roofs, from small crews that focus on residential retrofits to larger operations that also handle commercial standing seam work.
A metal roof is a bigger upfront cost than asphalt shingles, so the install matters more. Look for a contractor who specifies the gauge of steel (26 vs 24 vs heavier), explains their fastening or clip system, and can show you finished jobs in your neighbourhood, not just stock photos from the manufacturer. Ask how they handle flashing around chimneys and valleys, since that's where most metal roof leaks actually start, and confirm whether they carry manufacturer certification for the panel brand they're pitching. Warranty terms vary a lot between paint finish, panel, and workmanship, so get all three in writing.
Our scores weigh review volume and rating trends, how contractors respond to complaints, and signals like licensing and years in business.
