Cost to Re-Roof a Home in Canada in 2026 (With Snow Load Considerations)
2026 CAD pricing to re-roof a home in Canada, including asphalt shingle and metal roofing costs, per-square pricing, and how snow load requirements affect price in colder regions.
A roof is one of the biggest single expenses a homeowner faces, and Canada's climate — heavy snow loads, freeze-thaw cycles, and ice damming — makes roofing specs a bit different than in milder climates. Here's what re-roofing costs across Canada in 2026.
Re-roofing costs by material
Roofers typically price by the "square" (100 sq ft of roof area):
- Asphalt shingles (standard 3-tab or architectural): $400–$650/square installed
- Premium architectural/designer shingles: $650–$950/square installed
- Standing seam metal roofing: $1,000–$1,800/square installed
- Cedar shake: $1,200–$2,000/square installed
For a typical 2,000 sq ft roof (20 squares), that's roughly $8,000–$13,000 for a standard asphalt shingle re-roof, or $20,000+ for standing seam metal.
What adds to roofing costs in Canada specifically
Ice and water shield
Most Canadian building codes require ice and water membrane along eaves, valleys, and around penetrations to prevent ice damming — a much bigger concern here than in warmer climates. This typically adds $500–$1,500 to the total depending on roof complexity.
Snow load and structural requirements
In regions with heavy snow loads (much of the Prairies, Quebec, and parts of Ontario and Atlantic Canada), roofs need to meet higher structural load ratings under the National Building Code. If an inspection reveals the existing structure doesn't meet current snow load requirements, additional framing or sheathing reinforcement can add $2,000–$6,000 to a project.
Eavestrough and downspout upgrades
Many homeowners upgrade eavestroughs at the same time as a re-roof, especially in areas prone to ice damming, since a roof replacement is the easiest time to install heated cable channels or larger-capacity gutters. Standard eavestrough replacement runs $8–$14 per linear foot; heated gutter cable adds $6–$10 per linear foot.
Tear-off and disposal
Removing one layer of old shingles typically costs $100–$150/square; removing two or more layers (common on older homes) can add another $50–$100/square for disposal and extra labour.
Regional pricing
Roofing labour in Toronto and Vancouver tends to run 15–25% above the national average. Calgary and Edmonton pricing is generally close to the national midpoint, while Atlantic Canada and Quebec can run somewhat lower — though harsher winter climates in Quebec and the Prairies often mean higher-spec materials are standard, which can offset lower labour costs.
What a proper roofing quote should include
A complete roofing estimate should specify shingle brand/line, ice and water shield coverage area, ventilation (ridge vents, soffit vents), flashing replacement, and disposal. Roofers using AI-powered quoting tools can generate this level of line-item detail immediately after a roof measurement, which makes it much easier for homeowners to compare bids apples-to-apples.
