Replacing a roof is one of the biggest single-spend decisions GTA homeowners make. This thread breaks down costs and contractor advice for 2026 across all three main roof types.
Asphalt Shingles: GTA Baseline
Architectural (laminate) shingles are the 2026 standard. Cost: $5-$9/sq ft installed. Impact-resistant shingles: $8-$13/sq ft. Full re-roof on a 2,000 sq ft bungalow: $8,000-$18,000. Most GTA roofers carry a 25-year workmanship warranty alongside manufacturer coverage.
Metal Roofing
Standing-seam metal: $15-$25/sq ft installed. Steel shingles (slate or wood look): $12-$20/sq ft. Metal roofs handle Ontario ice dams better than asphalt and carry 40-50 year warranties. Insurance savings with some Ontario providers can offset part of the premium cost over 20 years.
Flat Roof and Low-Slope Systems
TPO membrane: $6-$10/sq ft. Modified bitumen: $5-$9/sq ft. EPDM rubber: $6-$11/sq ft. Flat roofs need clear drains - blocked drains are the top cause of flat roof failures in Toronto.
Contractor Red Flags
- Door-to-door solicitation after storms
- Demands for full payment upfront
- No WSIB or liability insurance proof
- No written manufacturer material spec
