What this calculator does
This calculator compares the full installed cost of every major Canadian roofing material — on the same job — so you can see upfront cost in CAD, cost per square foot, service life and cost-per-year side by side. Most cost calculators give you one figure for one material. This one runs the maths for the full menu and ranks them cheapest-to-most-expensive, with the lowest cost-per-year material highlighted separately.
It is the right tool to use when you have a Canadian roof to replace and you haven’t yet decided whether to stick with architectural asphalt, upgrade to standing-seam steel, switch to metal tile, or reinvest in cedar shake.
How to use it
- Enter the slope-adjusted roof area in square feet (Canadian convention is mixed — square feet is more common in roofing despite the metric residential standard). Our roof square footage calculator handles slope adjustment.
- Set the pitch. X/12 (rise per 12 inches of run) is the Canadian convention, same as US. A 6/12 pitch is typical for a 1980s suburban Canadian home; 8/12 is common on Maritime saltbox and Quebec mansards.
- Pick a region. Low — much of rural Atlantic Canada, rural Quebec, rural Prairies. Mid — Halifax, Quebec City, Calgary, Edmonton, Winnipeg, Regina, suburban Vancouver and Toronto. High — central Toronto, central Vancouver, Whistler, downtown Montreal, far-north sites with helicopter logistics.
- Pick complexity. Simple — gable or hip with no penetrations. Moderate — 1–2 dormers, single chimney, single valley. Complex — Quebec mansard with 4 valleys, Maritime saltbox with 3 dormers, multi-gable Victorian.
- Toggle tear-off + disposal if you’re replacing.
The table updates instantly. The “cheapest upfront” tile and “lowest cost per year” tile rarely show the same material.

*Asphalt service life in Canada is shorter than the US rating because of freeze-thaw cycles. Calculator uses these reduced figures.

Why “cost per year” beats “upfront cost” in Canada
Canadian winters are unforgiving on asphalt — manufacturer 30-year ratings don’t hold up to freeze-thaw cycling, and most asphalt roofs need replacing at 18–25 years versus the 30+ years they’d get in moderate climates. This pushes the cost-per-year calculation strongly in favour of metal in Canada more than anywhere else.
Take a 2,200 sq ft mid-region replacement:
- Architectural asphalt at C$15,000 = C$600/yr over 25 yrs (Canadian climate-adjusted).
- Steel standing-seam at C$32,000 = C$640/yr over 50 yrs.
- Steel shake at C$26,000 = C$520/yr over 50 yrs — the lowest.
Asphalt’s upfront advantage almost completely disappears once you account for Canadian climate-shortened life, while metal shake and steel standing-seam emerge as the cost-per-year winners. Add in 10–25% homeowners insurance discounts on impact-resistant metal in Alberta hail country and the metal advantage widens.
The calculator surfaces the lowest cost-per-year material automatically.
Cost drivers in detail
Pitch. A 4/12 pitch is “walkable” — labour multiplier 1.0. A 6/12 pitch needs careful footing — multiplier 1.05. An 8/12 pitch (common Maritime saltbox) requires harnesses and roof jacks — multiplier 1.18. A 10/12 pitch is half-speed — multiplier 1.32. A 12/12 pitch (45°, typical Quebec mansard) requires staging — multiplier 1.50.
Tear-off layers. Single layer: C$1.65/sq ft of labour. Double layer (allowed in some provinces, not all): C$2.10/sq ft. Triple layers cannot be recovered — full tear-off required.
Region. Toronto and Vancouver inner-ring run 22–32% above national. Calgary, Edmonton, Halifax, Quebec City: at or near average. Rural Atlantic, rural Saskatchewan, rural Manitoba: 12–18% below — though Maritime salt-air corrosion shortens metal life slightly.
Complexity. A 2,200 sq ft simple gable re-roofs in 3 days. The same square footage on a Quebec mansard with 4 valleys, 2 dormers, and copper detailing takes 6–8 days. Add 12% (moderate) or 28% (complex) to labour.
NBC 9.26.5 ice and water shield. Required for the lower 600 mm of every eave plus full valley and penetration coverage. Cost: C$0.65–C$0.90 per sq ft of underlay area. Already in the calculator.
Snow load. NBC 2020 Section 4.1.6 specifies Ss roof snow loads by municipality. Most existing roof structures handle their original material’s load — but switching from asphalt (~12 kg/m²) to slate (~50 kg/m²) typically requires structural upgrade. Engineer assessment runs C$1,500–C$3,500.
Hail. Alberta hailstorms cost CAD insurers C$2.5B+ in 2020 alone. Class 4 impact-resistant shingle is mandatory in some Calgary and Edmonton municipalities; insurance discounts of 10–25% apply elsewhere in hail country.
Asphalt vs metal vs cedar — which to actually pick
Architectural asphalt — the default for 65% of Canadian 2026 re-roofs. Pick architectural asphalt for: subdivision homes, budget-driven projects, and roofs in moderate climates (Vancouver Island, southern BC, Niagara fruit belt) where freeze-thaw is mild.
Steel standing-seam — the premium upgrade. Pick steel for: hail-prone Prairies, coastal Atlantic where shake won’t last, steep Quebec mansards, and homeowners planning to stay 15+ years. The Canadian climate amortises the upfront premium faster than any other market.
Steel shake / metal tile — for heritage replacements and homeowners who want the look of cedar or slate without the cost. Pre-formed steel panels stamped to look like cedar or slate. Lasts 50 years, weighs 1/3 of asphalt, qualifies for insurance discount.
Cedar shake — restricted to BC, parts of Ontario, and Maritime where local plans allow. Class B fire treatment required in Vancouver Island and BC interior. Lasts 25 years if maintained, 18 if neglected.
Slate / copper / zinc — for heritage Quebec, downtown Toronto, and high-end custom builds. Copper develops a green patina over 20 years and lasts 75–100 years.
Common gotchas that blow the budget
Reboarding. Many 1960s and earlier Canadian homes have 1×6 plank decking with gaps. Modern asphalt and metal need 7/16 OSB or 1/2 plywood overlay — C$2.50–C$3.50/sq ft, often catching homeowners off-guard.
Eavestroughs. Most Canadian re-roofs include eavestrough renewal as a matter of course: C$10–C$18 per linear foot for 5-inch K-style aluminum, C$22–C$32/lf for 6-inch. Don’t reuse 20-year-old gutters.
Soffits and fascia. Aluminum or vinyl soffit and fascia replacement runs C$8–C$14 per linear foot. Often bundled with the re-roof for cost efficiency on scaffold.
Skylight and chimney flashings. Velux replacement: C$650–C$1,250 per fixture installed. Lead chimney flashing renewal: C$450–C$900 per stack.
Snow guards. Required on standing-seam metal roofs over walkways, doorways, and driveways to prevent avalanche-style snow shed. C$8–C$18 per linear foot of guard, plus engineering. Not optional in BC mountains, Quebec, or Maritime.
