What this calculator estimates

This calculator gives you a line-by-line 2026 Canadian installed price for a PVC single-ply membrane roof. Whether you are re-roofing a 300 sq ft Toronto duplex flat roof over a kitchen addition, replacing a 12,000 sq ft Montreal restaurant roof, or specifying a 60,000 sq ft Calgary warehouse, the calculator follows the line-item structure CRCA-member roofers use on real quotes:

  • PVC membrane — 50-mil, 60-mil, 72-mil or 80-mil, standard PVC, KEE-modified Sarnafil, fleece-back or FiberTite PVC-CPA
  • Tear-off — removing the existing membrane, insulation and fasteners
  • Polyiso (ISO) insulation — R-20, R-30 or tapered ISO for slope
  • HD coverboard — DensDeck Prime or SECUROCK
  • Drain count — internal cast-iron drains and overflow scuppers
  • Kitchen-exhaust grease stacks — reinforced PVC boots at each grease-laden exhaust
  • Permit, disposal, weekend premium and extra labour

A $1,680 CAD minimum mobilisation fee applies in most Canadian markets even on small jobs.

Cost drivers

Membrane thickness and warranty tier. Sika Sarnafil G410 60-mil is the workhorse for mid-market Canadian commercial and restaurants. Carlisle Sure-Flex 80-mil and IKO Armourplan PSG-PT 80-mil are specified for provincial hospitals, school boards, federal buildings and any project requiring a 30-year non-pro-rated warranty.

PVC chemistry. Standard PVC is the baseline. KEE-modified PVC replaces low-molecular-weight phthalate plasticisers with high-molecular-weight KEE that does not migrate. Fleece-back PVC has a felt backing for fully adhered systems on uneven decks. FiberTite PVC-CPA is used on Canadian Air Force bases, RCMP detachments and pharma plants.

Attachment method. Mechanically attached is the fastest install (4,000 to 6,000 sq ft per day for a 2-person crew). Fully adhered is monolithic with the highest wind uplift but costs 15 to 20 percent more. RhinoBond eliminates linear seam weakness while keeping mechanical-attach speed. Ballasted is a legacy approach with significant dead-load implications.

Insulation and coverboard. Polyiso (PIR) is the dominant substrate. Two layers staggered prevent thermal bridging. NBC 9.36.2 mandates RSI 5.46 minimum in zone 5 and RSI 6.17 in zones 6 and 7A. Coverboard (DensDeck Prime or SECUROCK) protects the PVC from polyiso facer punctures and is required by Sika, Carlisle, IKO and Versico for 25+ year warranties.

Tear-off versus recover. NBC permits up to two layers of roof covering before tear-off is required. Recover is 25 to 35 percent cheaper than tear-off but is only permitted if the existing assembly is dry and structurally sound. Asbestos cement strip-out triggers provincial OHS notification.

Drains, grease stacks and penetrations. Cast-iron drains are $330 to $470 CAD each retrofit. Kitchen-exhaust grease stacks need reinforced PVC boots at $220 to $360 CAD each.

Storey, access and crane logistics. Single-storey is the cheapest install. Two-storey adds 18 percent. Three-storey or higher adds 40 percent for tower crane or telehandler at $1,400 to $2,800 CAD per day.

When PVC is the wrong choice in Canada

  • Warehouses, retail and office with no chemical exposure — TPO is 20 to 30 percent cheaper.
  • Steep-pitch single-family homes — asphalt shingles, metal panels or cedar shake are visually and structurally appropriate.
  • Heritage-designated buildings under Parks Canada or provincial heritage trusts — slate, copper or original materials may be required.
  • Deep-cold Northwest Territories or Nunavut sites — modified bitumen with SBS chemistry or EPDM may outperform on lifecycle in extreme cold.

Bidding strategy and red flags

Always get three written bids from CRCA-member contractors that itemise membrane brand, thickness, chemistry, CCMC reference, attachment method, polyiso R-value, coverboard, drain count and grease-stack count. A bid that says “PVC roof, $X per sq ft” with no line items is a red flag. Confirm:

  1. The contractor is on the manufacturer’s certified-applicator list.
  2. The bid includes wind-uplift documentation per NBC 4.1.7 for your municipality.
  3. The bid lists permit fee, disposal and crane mobilisation as separate line items.
  4. The bid includes a 2-year workmanship warranty plus the manufacturer’s material warranty.
  5. For restaurants, the bid identifies grease-boot count and confirms FM Global Data Sheet 1-29 compliance.
  6. The contractor is registered with the Ontario College of Trades, RBQ (Quebec), BC Roofing Contractors Association or equivalent provincial trade body.

Frequently asked questions

How much does a PVC roof cost per sq ft installed in 2026 in Canada?
In Canada, 60-mil mechanically attached standard PVC installs at $8 to $13 CAD per sq ft all-in for a typical low-slope commercial roof, including tear-off, R-20 polyiso, HD coverboard, drains, permit and disposal. 50-mil drops to $7 to $11 CAD per sq ft. 80-mil with 30-year warranty climbs to $11 to $17 CAD per sq ft. KEE-modified Sarnafil G410 adds 14 percent. FiberTite PVC-CPA adds 18 percent. A 2,000 sq ft single-storey 60-mil mechanically attached install with R-20 polyiso runs $16,000 to $26,000 CAD in 2026 CRCA member contractor pricing.

PVC versus TPO and EPDM in Canada — which handles winter best?
EPDM has the best deep-cold flex (proven down to -45 C) but loses on chemical resistance and is not heat-weldable. KEE-modified PVC (Sika Sarnafil G410 ELVALOY, Carlisle Sure-Flex KEE HP, IKO Armourplan PSG-PT) handles Canadian winter excellently down to -40 C without embrittlement — legacy phthalate-plasticised PVC was historically prone to cold-cracking but KEE chemistry effectively solved that in the 2000s. TPO is competitive with PVC at 20 to 30 percent lower cost where there is no grease or chemical exposure. For restaurants and food-service buildings across Ontario, Quebec, BC, Alberta and the Maritimes, KEE-PVC is the chain-spec default.
What is KEE-modified PVC and is it worth the premium in Canada?
KEE (ketone ethylene ester) is a high-molecular-weight plasticiser DuPont sells as ELVALOY. It replaces lower-molecular-weight phthalate plasticisers traditionally used in PVC. Because KEE does not migrate or evaporate under Canadian freeze-thaw cycles, KEE-modified PVC stays flexible for 30 to 40 years versus 18 to 25 for standard PVC. The leading KEE products in Canada are Sika Sarnafil G410, Carlisle Sure-Flex KEE HP, Versico VersiFlex KEE-HP and IKO Armourplan PSG-PT (made in Brampton, Ontario). Premium is 12 to 16 percent over standard PVC. Worth it for: hospitals, schools, federal buildings and provincial infrastructure.

Does PVC roofing meet NBC 9.26 and provincial building codes?
Yes. NBC 9.26 covers low-slope roofing. NBC 9.26.4 covers underlayment, NBC 9.26.6 covers asphalt and synthetic-membrane installation. NBC 9.36.2 covers thermal performance — under NBC 2020, low-slope re-roofs in climate zones 4 (Vancouver, lower mainland BC) require RSI 5.46 (R-31); zone 5 (Toronto, Ottawa, Montreal) requires RSI 6.17 (R-35); zone 6 (Calgary, Edmonton) requires RSI 6.17 (R-35); zone 7A (Winnipeg, Saskatoon) requires RSI 6.17 (R-35); zone 7B (Yellowknife, Whitehorse) requires RSI 7.22 (R-41). The leading PVC products carry CCMC evaluation reports (Sarnafil 12567-L, Sure-Flex 13045-L, IKO Armourplan 13892-L) and provincial Ontario Building Code SB-10, BCBC and NECB 2020 compliance.
Why do Canadian restaurants and chain operators use PVC roofing?
Kitchen exhaust loaded with airborne cooking grease coats the surrounding roof. Asphalt-based membranes (modified bitumen, BUR) and TPO swell and soften under prolonged grease exposure. PVC has excellent resistance to animal fats, vegetable oils and most kitchen chemicals. FM Global Data Sheet 1-29, CRCA Specifications Manual and chain operator specs (Tim Hortons, McDonald's CA, Subway, Harvey's, A&W Canada) require PVC within a 3-metre radius of any kitchen exhaust terminal. Reinforced PVC grease boots are specified at each exhaust stack. Source: CRCA Restaurant Roofing Bulletin; FM Global Data Sheet 1-29.
How long does a Canadian PVC roof last?
Standard 60-mil PVC delivers 22 to 28 years in the Canadian climate. KEE-modified Sarnafil G410, Carlisle Sure-Flex KEE HP, IKO Armourplan PSG-PT and Versico VersiFlex KEE-HP deliver 30 to 40 years. FiberTite PVC-CPA delivers 30 to 40 years. UV and freeze-thaw cycles in the Prairies and Northern Canada are more aggressive than in coastal BC and the Maritimes. Annual inspections, biennial cleaning and recoating with silicone or acrylic ($2 to $4 CAD per sq ft) extend service life. Source: CRCA field performance bulletins 2023-2025; CCMC long-term evaluation reports.
Do I need a permit for a PVC re-roof in Canada?
In most Canadian municipalities, low-slope roof replacement (full tear-off and re-cover) requires a building permit at $150 to $400 CAD per project. Recover applications without tear-off are often exempt. Toronto, Montreal, Vancouver and most large municipalities require licensed roofer sign-off. NBC 9.36.2 mandates U-value targets — for re-roofs in zone 5 and warmer, RSI 5.46 is the floor; zone 7B and 8 require RSI 7.22 or better. Restaurant re-roofs in Toronto, Mississauga, Calgary and Vancouver may also require Public Health approval if grease-boot detailing changes.
Can PVC and TPO be heat-welded together on a Canadian flat roof?
No. PVC and TPO are chemically incompatible — they will not heat-weld to each other. If you are doing a partial replace or tying into an existing roof, match the existing membrane chemistry. Termination bars with butyl tape and metal cleats are the only mechanical way to terminate dissimilar membranes. Most CRCA contractors prefer a full tear-off and single-chemistry re-roof for warranty and seam-integrity reasons.
What is the cheapest PVC option for a Canadian residential flat roof?
For a small (200 to 600 sq ft) residential flat roof over a garage, addition or porch, the cheapest PVC route is 50-mil mechanically attached IKO Armourplan or Bauder Thermoplan T with R-20 polyiso. Expect $2,800 to $5,500 CAD installed by a CRCA contractor for a 300 sq ft roof. Cheaper than 60-mil TPO by only 5 to 10 percent, and worth it if the flat roof is over a kitchen or close to a kitchen exhaust. Avoid bidders below $2,300 CAD for any 300 sq ft job — they are skipping the polyiso upgrade required under NBC 9.36.
