What this calculator estimates

This calculator gives you a line-by-line installed 2026 Canadian price for a composite (synthetic slate, polymer shingle, or synthetic clay-tile) roof, whether you are speccing DaVinci Roofscapes (the leader by CRCA member spec), EcoStar by Carlisle SynTec (LEED Canada and Built Green choice), Brava Roof Tile (lightest), Inspire by Boral (architect-specified), or F-Wave REVIA (budget). The calculator follows the line-item structure that CRCA member contractors use on real quotes:

  • Composite material — selected by profile (synthetic slate, cedar-look shingle, or synthetic clay tile), brand, and thickness/pattern
  • Tear-off — removing the existing roof down to the deck
  • Ice-and-water shield + synthetic underlay — full-deck ice-and-water shield north of the 49th parallel per NBC 9.26, plus synthetic underlay above
  • Hip and ridge cap — matched composite cap per linear foot
  • Copper or pre-painted aluminum valley flashing — per linear foot (copper preferred for premium spec, aluminum for value)
  • Pipe and skylight penetrations — per-unit prefabricated flashing kits
  • Municipal building permit, disposal, and weekend premium

A CAD 520 minimum service-call floor applies in most Canadian composite markets — even small composite repairs need a manufacturer-certified installer, a colour-matched bundle delivered, and ladder/scaffold access.

How to use it

  1. Enter roof area in square feet. For a typical Canadian detached home this is 1,800 to 3,200 sq ft, townhouses 1,200 to 2,000 sq ft.
  2. Pick profile — synthetic slate (premium new-build), cedar-look shingle, or synthetic clay tile.
  3. Pick brand — DaVinci (default), EcoStar (LEED Canada / Built Green), Brava, Inspire, F-Wave REVIA, or generic value-tier.
  4. Pick thickness/pattern — single-thickness, multi-width staggered (default), or premium thick.
  5. Set scope — spot repair (15% of area), partial replace (45%), or full reroof (100%).
  6. Set storey count — single-storey 1.0x, two-storey 1.2x, three-storey 1.45x.
  7. Set access difficulty — easy (drive-up) is 1.0x, moderate (rear garden) 1.1x, hard (no ladder access / lift needed) 1.3x.
  8. Enter hip & ridge cap and copper or aluminum valley in linear feet, and pipe / skylight penetrations count.
  9. Toggle tear-off, ice-and-water shield, municipal permit, disposal, and weekend premium, plus any extra labour hours.

Toronto GTA, Vancouver Lower Mainland, Calgary, and Ottawa carry a 10 to 18 percent uplift; remote (NWT, Yukon, Nunavut, northern BC, northern QC) carries 30 to 60 percent for freight and crew lodging.

Cost drivers

Brand premium. DaVinci sets the spec ceiling for CRCA member contractors. EcoStar tracks 8 percent below DaVinci with 80 percent post-industrial recycled content (preferred for LEED Canada and Built Green). Brava and Inspire track within 5 percent of EcoStar. F-Wave REVIA undercuts DaVinci by about 22 percent. Generic value-tier polymer can be 30 to 45 percent below DaVinci but typically carries a 30-year warranty instead of 50.

Profile premium. Synthetic slate (the default for premium custom homes in Toronto, Vancouver, Calgary) is the baseline. Cedar-look shingle is about 8 percent cheaper. Synthetic Spanish/barrel tile is 5 percent more expensive — rare in Canada outside Mediterranean-styled new builds.

Heritage district status. Composite is typically refused in Old Quebec UNESCO, Old Montreal, Old Toronto, Vancouver Heritage Register, Edmonton’s Old Strathcona, Winnipeg’s Exchange District. Confirm with municipality before committing for any pre-1950 property.

Cold-climate detail. Zones 7 and 8 (most of Canada north of the 49th parallel) require full-deck ice-and-water shield per NBC 9.26 and most CRCA contractor spec. Spring thaw in zones 7 and 8 routinely ice-dams the entire roof — the standard 3-ft eave strip is insufficient. This adds 6 to 10 percent to the per-sq-ft rate vs the standard eave-strip-only spec.

Roof complexity. A simple 6/12 to 8/12 gable installs fast. Cut-up roofs with multiple dormers, valleys, hip-and-ridge transitions, skylights, and chimneys add 20 to 40 percent vs simple gable because every transition needs copper or aluminum flashing in linear feet and slows the crew.

Canadian code, standards, and certifications

  • NBC 2020 Part 9 Section 9.26 — Roofing (covers composite slate via 2023 amendment).
  • CSA A123.71 — Standard test method for hail-impact resistance of asphalt and composite shingles (Class 1 to 4).
  • ULC S107 — Standard methods of fire tests of roof coverings (Class A, B, or C).
  • CCMC Evaluation Reports — DaVinci CCMC 13720-R, EcoStar CCMC 13921-R, Inspire CCMC 13654-R, Brava CCMC 14021-R, F-Wave CCMC 14150-R (verify current at nrc-cnrc.gc.ca/ccmc).
  • Provincial building codes — OBC (Ontario), BCBC (British Columbia), ABC (Alberta), QBC (Quebec via RBQ), all reference NBC 9.26 with provincial amendments.
  • ASTM D3161 — Wind resistance test for roof shingles (Class A, D, F). DaVinci is rated Class F (110 mph).
  • CSA O121 — Douglas fir plywood standard for sheathing.
  • Provincial Occupational Health & Safety Acts — Fall protection above 3 m (Ontario OHSA, BC OHS, Alberta OHS, Quebec CNESST, Atlantic provinces OHS).

Use a CRCA member contractor with manufacturer certification for any composite project — without certification the 50-year manufacturer warranty can be reduced to 30 years.

Diagnostic step-by-step before quoting

  1. Verify the deck is sound — open soft spots from the attic side. Quebec and Atlantic Canada projects often turn into partial deck-replacement projects (CAD 70 to CAD 110 per 4x8 sheet of CSA O121 plywood installed).
  2. Check hail history — search your address on Environment Canada Storm Events Database. Repeat hail history in AB, SK, MB makes the Class 4 insurance discount compelling.
  3. Confirm CCMC report is current — nrc-cnrc.gc.ca/ccmc lists current evaluations.
  4. Get three CRCA member bids that itemize composite brand and profile, ice-and-water shield extent (eave-only vs full-deck), synthetic underlay, copper or aluminum valley, hip & ridge cap, pipe and skylight flashings, and municipal permit as separate line items.
  5. Confirm manufacturer-certified-installer registration — without this, the 50-year warranty drops to 30 years on most brands.

Avoiding scams and overcharging

Door-knocker roofers occasionally push composite re-roof after a hailstorm in AB, SK, MB when only spot repair is needed — Class 4 composite is designed to survive most hailstorms intact. Red flags include claims that “the entire roof needs replacement” when only the south and west elevations show legitimate strike marks, refusal to identify the composite brand they propose, refusal to commit to the manufacturer’s certified installer program, no CRCA membership, no proof of CAD 2M+ general liability insurance, and cash-only or e-transfer-immediate demands. Reputable Canadian composite roofers in 2026 carry CAD 5M general liability, CAD 2M auto, WSIB / WCB clearance certificates (provincial), are CRCA members, hold at least one manufacturer-certified-installer registration, and provide a written workmanship warranty. Verify CRCA at roofingcanada.com, WSIB / WCB clearance with your provincial authority, and HomeStars rating before signing.

Frequently asked questions

How much does a composite roof cost in 2026 in Canada?
Most Canadian homeowners pay CAD 7 to CAD 13 per sq ft installed for a synthetic slate or shake composite roof in 2026, all-in with tear-off, full-deck ice-and-water shield (zone 4 to 8 — most of Canada), synthetic underlay, hip and ridge cap, copper or pre-painted aluminum valley, pipe and skylight penetrations, and municipal building permit. A 2,200 sq ft single-storey home with DaVinci Bellaforte Slate lands around CAD 22,500 to CAD 30,500. EcoStar Majestic Slate is about 8 percent cheaper, Brava 10 to 12 percent cheaper, F-Wave REVIA roughly 22 percent cheaper.

Composite vs natural slate vs cedar shake — which makes sense in Canada?
Composite makes sense when you want the look of slate or cedar without the weight, cost, or maintenance — particularly in zones 6, 7, and 8 (most of Canada north of the Great Lakes) where the freeze/thaw cycle accelerates damage to natural materials. Natural slate (Quebec Cossic, Vermont, Welsh) costs CAD 18 to CAD 32 per sq ft installed and weighs 800 to 1,500 lb per square — typically needs roof framing upgrade to NBC 9.4. Composite slate at 150 to 250 lb per square installs on existing 9.4-compliant framing. Cedar shake (BC Western Red, Quebec Eastern White) costs CAD 8 to CAD 13 installed but has a 25 to 35-year service life in Canadian climate vs composite's 50 years. Composite is also Class 4 impact (CSA A123.71) — meaningful for hail-prone Alberta, southern Saskatchewan and Manitoba and qualifies for 15 to 30 percent insurance premium discounts from Intact, Aviva, Co-operators, and Wawanesa.
DaVinci vs EcoStar vs Brava vs Inspire vs F-Wave — which composite brand is best in Canada?
DaVinci Roofscapes (Kansas, distributed Canada by Convoy Supply, IKO Industries, and AllRoofing) is the spec-leader for premium custom homes — 50-year material warranty, ULC S107 Class A fire, CSA A123.71 Class 4 impact. EcoStar by Carlisle SynTec uses 80 percent post-industrial recycled rubber and plastic — preferred for LEED Canada and Built Green projects. Brava Roof Tile pioneered the synthetic Spanish/barrel-tile profile (rare in Canada outside Mediterranean-styled new builds in Vancouver, Toronto, Calgary). Inspire by Boral competes head-to-head with DaVinci. F-Wave REVIA is the budget option at 22 percent below DaVinci. For most Canadian homes wanting the slate look, DaVinci Bellaforte Slate is the default — distributors are Convoy Supply (BC, AB, ON, QC), IKO (national), and AllRoofing (ON, QC).
Is Class 4 impact really worth it and how much will my Canadian insurance discount be?
Yes in hail-prone provinces. Class 4 impact rating (CSA A123.71 / UL 2218) is the highest hail rating — a 2-inch steel ball dropped from 20 ft does not crack the shingle. All major composite brands carry Class 4. Canadian insurance discounts vary by carrier and province: Intact, Aviva, Co-operators, and Wawanesa offer 15 to 30 percent premium discounts in AB, southern SK, southern MB, and southwest ON (the hail alley); RSA and TD Insurance offer 10 to 20 percent in BC, QC, Atlantic provinces. On a CAD 2,400 annual home insurance policy that is CAD 360 to CAD 720 per year — composite roofs typically pay back the premium over architectural asphalt within 10 to 14 years through insurance savings alone, before counting the longer service life. Get a written declaration page reference from your broker before signing, and submit the manufacturer's CSA A123.71 / UL 2218 Class 4 certificate and installation invoice.
How long does composite installation take and what is the warranty?
A 2,200 sq ft single-storey full reroof with DaVinci Multi-Width Slate takes 6 to 9 working days with a 3-person crew, weather permitting — about 30 percent faster than natural slate and 15 percent faster than BC cedar shake. The standard manufacturer warranty is 50 years material on DaVinci, EcoStar, Inspire and F-Wave REVIA; Brava is lifetime limited. All major brands transfer to subsequent homeowners (sometimes with a small re-registration fee at year 30). Installer workmanship warranty should be at least 7 years for a CRCA member. Ask for the manufacturer-certified-installer registration number (DaVinci Masterpiece Contractor, EcoStar Premium Contractor, Brava Certified Installer) — without it, the 50-year manufacturer warranty can be reduced to 30 years.
What pitch, underlay, and ice-and-water shield does composite need in Canada?
Composite slate and shake require a minimum pitch of 4/12 (about 18 degrees) per NBC 2020 Part 9 Section 9.26 and manufacturer specs. Some brands (DaVinci, Brava) approve down to 3/12 with double underlay and reduced warranty. There is no practical maximum pitch — composite is used on Quebec church spires at 18/12 (about 60 degrees). Full-deck ice-and-water shield is required in zones 6, 7, and 8 (most of Canada) per NBC 9.26 — the eave-to-warm-wall + 24 inches minimum is the strict NBC requirement, but most CRCA contractors specify full-deck ice-and-water shield north of the 49th parallel because spring thaw in zones 7 and 8 routinely ice-dams the entire roof. Synthetic underlay (one layer of upgraded polypropylene like IKO Stormtite) above the ice-and-water shield is also standard. In Quebec and Atlantic Canada, additional snow-and-rain barrier at hips and ridges is recommended per RBQ guidance.
Do I need a municipal building permit for a composite re-roof in Canada?
Most municipalities yes. Like-for-like re-roof (asphalt to asphalt) is often Permit-Exempt under municipal by-laws (Toronto, Vancouver, Calgary, Edmonton, Winnipeg, Ottawa, Halifax). Changing from asphalt or cedar to composite is typically NOT like-for-like and requires a Building Permit because the roof material and Class A fire/Class 4 impact rating change. Quebec municipalities require permis de rénovation under the Régie du bâtiment du Québec rules. Heritage districts in Old Quebec, Old Montreal, Old Toronto, Vancouver Heritage, Edmonton's Old Strathcona, and similar typically require natural slate or cedar — composite often refused. Always check with your municipality's building department before committing.
What is the difference between Bellaforte, Multi-Width, Single-Width, and Aledora?
These are the major composite slate profiles. DaVinci Multi-Width Slate (default) mimics 5 in, 7 in, 9 in, and 12 in real slate widths stacked randomly — most realistic, the spec-equivalent of random-width natural slate. DaVinci Single-Width Slate is uniform 12 in width, premium thick, 25 percent more expensive. DaVinci Bellaforte Slate is a locking-panel system that installs 30 percent faster than Multi-Width with the same visual but slightly less random pattern — popular with Canadian CRCA member contractors because cold-weather install windows are short. EcoStar Majestic Slate, Brava Old World Slate, Inspire Classic Slate, and F-Wave REVIA Slate are equivalents to DaVinci Multi-Width. For shake profile (BC or Quebec cedar shake equivalent): DaVinci Single-Width Shake, EcoStar Seneca Shake, Brava Cedar Shake, and Inspire Aledora Shake.
