Roofing is one of the trades most vulnerable to fly-by-night operators in Toronto. Storm-chasing crews, unlicensed workers, and companies that disappear after warranty issues are genuine problems. Here’s how to find a legitimate roofer.
What to Check for Every Roofer
WSIB clearance: Roofing is a high-injury trade — falls from roofs are among the most serious workplace accidents. WSIB coverage is essential. Verify directly at wsib.on.ca.
Insurance: $2M+ general liability. Verify the certificate, not just a claim.
Manufacturer certification: For premium shingle systems (Owens Corning Platinum, IKO Dynasty, GAF Timberline) that come with enhanced warranties, the contractor must be certified by the manufacturer. Ask which systems they’re certified on.
Permit: Roof replacement in Toronto doesn’t always require a permit for like-for-like replacement. But if there are structural repairs or decking replacement, a permit is required. Know before you agree to a contract.
Warning Signs in Roofing
- Door-to-door solicitation after a storm (storm-chasing crews often do poor work quickly and disappear)
- Cash-only quotes
- “We have leftover materials from a nearby job” (this is a well-documented scam approach)
- Very low bids — shingle roofing materials cost what they cost; extremely low bids mean shortcuts somewhere
What a Good Roofing Quote Includes
- Shingle brand, model, and colour specified
- Whether old shingles are stripped (always better than re-shingling over)
- Ice and water shield specification for the first 3+ feet from eaves and all valleys (Toronto winters require this)
- Drip edge specification
- Ventilation assessment and any planned changes
- Warranty terms (workmanship + manufacturer)
