Roof replacement timing matters in Canada — most roofing contractors are busiest from May to October. Book in late winter for the best pricing and scheduling. Asphalt shingles remain the most popular choice (85% of Canadian homes) with a 20–30 year lifespan. Metal roofing costs 2–3x more upfront but lasts 50+ years and handles snow loads better. Always get a written warranty that covers both materials and workmanship.
Roof pitch (steepness) significantly affects cost — steep roofs (8/12+) require extra safety equipment and time. Multiple layers of old shingles requiring removal add $1,000–$3,000. Skylight additions cost $1,500–$4,000 each. Ice and water shield membrane in valleys and edges adds $500–$1,500 but is essential in Canadian climates.
💡 Pro Tip
Ask your contractor about upgrading to impact-resistant (Class 4) shingles — some home insurance companies offer 10–28% premium discounts for hail-resistant roofing, which can offset the higher material cost over time.

London sits in southwestern Ontario's snow belt, receiving 194 cm of snow annually — significantly more than Toronto.
