Frequently Asked Questions — Roofing Contractors
- How many roofing contractors are in the directory?
- Our directory lists 100 verified roofing contractors across 49 cities in Ontario.
- What is the average rating for roofing contractors?
- The average Google rating for roofing contractors is 4.9 stars based on 20,371 combined reviews.
- Do roofing contractors need a licence in Ontario?
- No mandatory Ontario license, but look for certifications. Not a compulsory trade in Ontario, but reputable roofers carry liability insurance, WSIB, and manufacturer certifications (GAF, CertainTeed, IKO).
- How much does roofing work cost in Ontario?
- Costs vary by project and location. Shingle Replacement: $5,000-$15,000 (average home). Flat Roof: $4,000-$12,000 (per 1000 sqft). Repair: $300-$1,500 (per repair). Get at least 3 quotes.
- How do I find a good roofing contractor?
- Check Google reviews, verify WSIB coverage at wsib.ca, confirm they pull required permits, get 3 written quotes, and never pay more than 10-15% deposit upfront.
- What is the best roofing material for Ontario weather?
- Architectural asphalt shingles (30-50 year warranty) are the most popular choice for Ontario's freeze-thaw cycles. Metal roofing is gaining popularity for its 50+ year lifespan and snow-shedding ability. For flat roofs, TPO or EPDM membranes perform best in Canadian winters.
- How do I know if my roof needs replacement?
- Signs include: shingles curling, cracking, or missing granules; daylight visible through roof boards; sagging roof deck; age over 20 years; multiple leaks or repairs in the past 2 years; and higher energy bills from poor insulation. Get a free inspection from a reputable roofer.
- Does home insurance cover roof replacement in Ontario?
- Ontario home insurance typically covers roof damage from sudden events (storms, falling trees, fire) but NOT normal wear and tear or age-related deterioration. Document storm damage immediately and file your claim before starting repairs.
