Toronto FAQ
How much does a new roof cost in Toronto in 2026?
A full asphalt-shingle re-roof on a typical Toronto detached home (1,500–2,200 sq ft of roof area) costs $9,500 to $24,000 before HST in 2026. Architectural shingles sit at $7.50–$11.50 per sq ft installed, including tear-off, ice & water shield to code, synthetic underlayment and standard ventilation.
How do I verify a Toronto roofer is legitimate?
Verify a Toronto roofer in four steps: (1) WSIB clearance certificate (check the number on the WSIB portal), (2) $2M minimum civil liability insurance with a current certificate, (3) City of Toronto building permit for any structural change, (4) written contract with start/end dates, brand and grade of shingle, and a clear payment schedule with no more than 10% deposit.
Do I need a permit to replace my roof in Toronto?
You do not need a City of Toronto building permit for a like-for-like asphalt shingle replacement. You do need a permit when changing the roof structure, adding a skylight, changing slope, or converting a flat roof to sloped (or vice versa). Always confirm with Toronto Building before signing.
What is the best time of year to replace a roof in the GTA?
The best window for a GTA roof replacement is late April to early October, when shingles seal properly under sun exposure. Avoid below-5°C installs unless the contractor hand-seals every shingle — otherwise the self-seal strip will not bond before the first ice-damming event.
