What this calculator does

This calculator gives you a full installed-cost estimate for replacing a sloped roof in Canada. It accounts for:

  • Material — architectural asphalt shingles (the dominant Canadian residential choice), 3-tab asphalt, premium asphalt, standing-seam metal, corrugated steel, cedar shake, concrete tile, clay tile, and natural slate
  • Labour — adjusted for pitch and roof complexity per NBC 9.26
  • Tear-off — single, double, or triple existing layers
  • Disposal — landfill tipping varies by province (BC, Ontario, Quebec are highest)
  • Ice and water shield — required by NBC at eaves and valleys
  • Underlayment — synthetic or felt
  • Gutters and downspouts — optional, by linear footage
  • Permit + miscellaneous — typically 3% of subtotal, minimum $450 CAD

How to use it

  1. Get the roof area — measure each plane’s slope-adjusted area in square feet (Canada uses mixed units; sq ft is standard for roofing). Use our roof square footage calculator for slope adjustment.
  2. Set the pitch — Canadian pitched roofs typically run 6/12 to 9/12. Steeper than 8/12 needs harnesses.
  3. Pick a material — architectural asphalt is the dominant choice in 2026 (about 80% of Canadian residential replacements per CRCA). Standing-seam metal is the fastest-growing premium option, especially in Quebec and the Maritimes.
  4. Region — Toronto, Vancouver, Ottawa: 18–28% above national. Calgary, Edmonton, Montreal: 5–12% above. Winnipeg, Halifax, Regina, Saskatoon: at or near average. Atlantic Canada outside major cities: 8–15% below.
  5. Complexity — simple gable: “simple”. One or two dormers, one chimney: “moderate”. Multiple gables, hips, valleys, multiple stacks: “complex” — adds 12–28% labour.
  6. Tear-off, ice-and-water, gutters — toggle and quantify.

Cost drivers in detail

Roof size. Linear scaling per sq ft, but very small roofs (under 1,000 sq ft) carry a $3,500–$5,500 CAD mobilization premium.

Pitch. A 6/12 pitch is most common — labour multiplier 1.05. An 8/12 pitch requires roof jacks — multiplier 1.18. A 12/12 pitch (45°) on Victorian or Queen Anne homes requires staging — multiplier 1.50.

Tear-off layers. Single layer: $1.85–$2.40 CAD per sq ft. Double layer: $2.40–$3.00. Three layers (now banned by NBC 9.26.4 in most cases) requires complete tear-off plus deck inspection.

Region. Toronto and Vancouver lead Canadian costs. Ottawa, Montreal, Calgary, Edmonton mid-pack. Winnipeg, Halifax, Saskatoon, regional centres lower. Northern and remote communities (Iqaluit, Yellowknife, Whitehorse) can be 50–100% above national due to material shipping.

Roof complexity. Simple Ontario bungalow gable: 2–3 days. Toronto Victorian with multiple gables, dormers, slate-tile spires: 8–14 days.

Ice and water shield. NBC 9.26.5 requires 36 inches up from eaves. In Northern Ontario, Quebec, Newfoundland: 6 feet recommended. Adds $0.65 per sq ft to underlay cost. Single most important Canadian roofing detail.

Insulation upgrade. NBC 9.36 minimum for new roofs is RSI 8.8 (R-50) in zones 5–7A and RSI 10.6 (R-60) in zone 7B-8. Many older Canadian homes have R-20 or less. Topping up adds $1.65–$2.40 per sq ft.

Soffit and ridge ventilation. NBC 9.19.1 requires 1:300 ventilation ratio. Many older homes are under-vented. Adding continuous soffit vent and ridge vent during the re-roof is $250–$450 in materials and $0.40–$0.65 per sq ft labour.

Asphalt vs metal — the Canadian choice

Architectural asphalt shingles are the default for 80% of Canadian roofs. IKO, GAF, Owens Corning, BP, and CertainTeed are the major brands. 22-year wear life in most of Canada (less in the Prairies, more in coastal BC and Atlantic Canada). Can be installed by any roofer; replacements easy to source. Best for: Ontario suburban homes, Quebec residential, Atlantic Canada, BC interior.

Standing-seam metal is the upgrade pick. 50+ year life. Sheds snow cleanly (a major advantage in Quebec, Northern Ontario, Atlantic Canada). 30–50% more expensive than architectural asphalt but cheaper per year over service life. Pick metal for: heavy snow load areas, coastal salt-air zones, hail-prone Prairies (Calgary, Lethbridge, Saskatoon), and roofs you want to last 50+ years.

Cedar shake is regional — common on West Coast (BC and Vancouver Island) heritage and craftsman homes. Western red cedar (Class A fire-treated) lasts 25–30 years. Banned or restricted in many BC fire-zone bylaws.

Concrete tile is uncommon in Canada — freeze-thaw cycles and snow load make it expensive to engineer properly. Found mostly on Mediterranean-style homes in lower mainland BC and southern Ontario.

Natural slate is rare — historic homes in Quebec City, Old Montreal, and parts of Toronto. 100+ year life. Specialized installers only.

Common gotchas that blow the budget

Decking replacement. Roofers usually quote replacing 1–3 sheets at no charge. Anything beyond runs $75–$110 CAD per sheet (32 sq ft / sheet). Older Canadian roofs (40+ years, 1×6 plank decking) often need full re-decking — $2.50–$3.50 per sq ft additional.

Ice damage to fascia and eaves. Years of ice damming destroy fascia boards and soffit panels. Once exposed at re-roof, expect $400–$1,500 to replace damaged eaves trim.

Chimney flashings. Old metal flashings should always be replaced. New stainless steel chimney flashing kit: $400–$800 installed. Brick chimney repointing during the same scaffold setup: $400–$1,200.

Skylight replacement. Old skylights at re-roof time should be replaced — frame and flashing are at end of life. Velux fixed skylight installed: $550–$950. Velux solar-vented: $1,200–$2,000.

Solar panel re-fix. Removal and reinstallation of solar PV adds $2,500–$5,500 CAD. Always re-roof first if you’re considering solar.

Asbestos shingles. Pre-1980 Canadian homes occasionally have asbestos-cement shingles. Licensed removal under provincial OHS regs runs $7–$11 per sq ft. Get a sample tested before tear-off if there’s any doubt.

When to repair vs replace

Repair makes sense if:

  • Roof under 60% of expected life
  • Damage is localized (a few missing shingles, one valley)
  • No widespread granule loss or curling
  • Decking under damage is dry

Replace if:

  • Past 75% of expected life
  • More than 15% of field shows issues
  • Multiple ice dam leaks
  • Multiple repairs haven’t held
  • Adding solar in next 5 years

Frequently asked questions

How much does a new roof cost in Canada in 2026?
Replacing a roof on a typical 2,000 sq ft Canadian home costs $9,500 to $18,500 CAD for architectural asphalt shingles, $22,000 to $42,000 for standing-seam metal, and $18,000 to $30,000 for cedar shake in 2026. Toronto and Vancouver run 18–28% above the national average. Halifax, Winnipeg, Calgary at or near average. Smaller centres in the Prairies and Atlantic Canada run 8–15% below.

Do I need a building permit to replace my roof?
Like-for-like roof replacements (same material, same coverage area) are typically exempt from building permit requirements in most Ontario, Quebec, BC, and Alberta municipalities — but you should always confirm with your local building department. A change in material (e.g., shingles to metal) usually requires a permit. Permits typically run $150–$450. Roofs over a certain area (varies by jurisdiction) and any structural changes always require permits and Ontario Building Code or BC Building Code compliance.
What's the best type of roof for Canadian winters?
Standing-seam metal handles snow loads, ice dams, and freeze-thaw cycles better than any other material. Snow slides off cleanly, ice dams are reduced (smooth surface), and the system has no granules to lose. Architectural asphalt is fine for most of Canada with proper ice-and-water shield (NBC requires 36 inches up from eaves, more in zones with severe ice damming). Concrete tile is uncommon in cold climates — freeze-thaw stresses the tiles. Avoid 3-tab asphalt — they don't seal properly in cold weather and lift in wind.
How does ice and water shield work?
Ice and water shield is a self-adhered modified bitumen membrane that seals around nails and creates a waterproof barrier under your shingles. NBC 9.26.5 requires it from the eave edge up the roof to a point at least 12 inches inside the exterior wall line — typically 36 inches of coverage. In severe ice damming zones (Northern Ontario, Northern Quebec, the Prairies, Newfoundland), 6 feet of coverage is recommended. Cost is about $0.65 CAD per sq ft installed. The single most important detail in a Canadian re-roof.
Will my home insurance cover roof replacement?
Insurance covers roof replacement only when damage is from a covered peril — windstorm, hail, falling tree, fire. Wear and tear, age-related failure, and gradual leaks are excluded. Most Canadian insurers depreciate roof claims heavily on roofs over 15 years old under Actual Cash Value policies. With Replacement Cost Value coverage and recent storm damage, insurance typically pays for full replacement minus your deductible. Get a roof inspection before filing — adjusters routinely deny claims that look like deferred maintenance.
How long should a Canadian roof last?
Architectural asphalt: 20–25 years in coastal BC, 18–22 years in Ontario and Quebec, 15–20 years in the Prairies (more sun and wind cycles). Standing-seam metal: 50+ years anywhere in Canada. Cedar shake: 25–30 years in dry climates, 18–22 years in coastal BC and Maritimes (moisture). Concrete tile: rare; not recommended for severe winter zones.
Should I replace my roof in winter?
Generally no — most adhesives and seal strips on shingles need temperatures above 5°C (40°F) to bond properly. Asphalt shingles installed in cold weather may not seal until the next warm spell, leaving them vulnerable to wind. Spring (April–June) and fall (September–November) are ideal in most of Canada. Emergency winter replacements use cold-weather adhesives and hand-sealing every shingle — adds 8–15% to the cost.
Should I add attic insulation when re-roofing?
It's a great time to do it — you have access from above. The 2026 NBC minimum for new roofs is RSI 8.8 (R-50). Many older Canadian homes have R-20 or less. Topping up with blown-in cellulose or fibreglass batts costs $1.65–$2.40 CAD per sq ft and pays back in 4–7 years through lower heating bills. Make sure to upgrade roof ventilation at the same time — without proper soffit and ridge venting, more insulation accelerates ice damming.
