Residential roofing covers everything from a full tear-off and re-roof to shingle repairs, flashing fixes, ice dam remediation, and small jobs like replacing a vent boot or patching a leak around a chimney. In Toronto, that also means dealing with old brick chimneys, steep century-home rooflines, flat or low-slope sections on additions and garages, and building code requirements that vary by structure type and neighbourhood. We track 89 residential roofing businesses serving the city, ranging from small owner-operated crews to larger installation companies that also handle insurance and storm damage claims.
Before hiring, ask for proof of WSIB coverage and liability insurance, a written scope of work (not just a price), and the manufacturer certifications tied to the shingle or membrane brand being proposed. Get more than one quote if the job is a full replacement, and ask how the crew handles disposal, deck repairs found once the old roof comes off, and warranty terms on both labour and materials. A clear contract with start and completion dates, payment schedule, and cleanup terms is a good sign the company runs an organized operation.
Our scoring weighs verified licensing and insurance, how a company communicates during quoting and the job itself, the consistency of past customer feedback, and how disputes or callbacks get resolved. For a shortlist of the highest-scoring companies in this category, see our ranked guide to Toronto's best roofing contractors. The scoring criteria and data sources behind every listing are explained on our methodology page.
