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.
Montreal offers moderate renovation costs compared to Toronto and Vancouver, with a large pool of bilingual contractors. The city's distinctive triplex and duplex architecture means many renovations involve shared walls and multi-unit considerations. Quebec's Régie du bâtiment (RBQ) licensing ensures contractor quality but also means only licensed professionals can perform major work.
Montreal requires permits from the borough (arrondissement) for structural modifications, plumbing, electrical work, and exterior changes. Processing times vary by borough — the Plateau and Ville-Marie are typically slower (3–6 weeks). Quebec law requires all contractors performing work over $5,000 to hold an RBQ licence.
Montreal's extreme temperature range (-10°C in January to 27°C in July) demands high-quality insulation and materials rated for severe freeze-thaw cycles. Snow loads are a key factor for roofing projects, and ice dams are common on older homes without proper attic ventilation.
In 2026, a roofing renovation in Montreal costs between $6,660 (budget) and $31,668 (premium). The average standard cost ranges from $9,513 to $19,793.
Montreal has a cost index of 105% relative to the Canadian national average. Prices are near the Canadian average. This index accounts for local labour costs, materials, and permit fees.
A standard roofing renovation typically takes 2 to 5 days. Premium projects or unexpected issues (e.g. structural problems) can extend the timeline. Always get a detailed schedule from your contractor.
A roofing renovation typically yields a 60–70% return on investment at resale in Canada. ROI depends on material quality, the local real estate market in Montreal, and the property's condition.
