2026 Calgary new roof cost by shingle type (per square foot, installed)
These are all-in installed Calgary numbers — materials, labour, full tear-off, underlayment, ice-and-water shield, flashings, ridge venting, GST, magnet sweep, workmanship warranty. Multiply by your roof’s field square footage (NOT your home’s floor plan) to get a rough total.
- 01Class 3 architectural asphalt (IKO Cambridge, OC TruDefinition Duration, GAF Timberline HDZ, Malarkey Highlander, BP Mystique): $5.20–$6.40 per sq ft. On a 30-square (3,000 sq ft) Calgary roof that is $15,600–$19,200 all-in. Adequate spec, but not recommended in Calgary’s documented hail belt without an insurance plan.
- 02Class 4 impact-rated asphalt (Duration STORM, IKO Nordic, Malarkey Vista AR, GAF Timberline AS II, BP Mystique 42 AR): $6.10–$7.20 per sq ft. On a 30-square roof that is $18,300–$21,600 all-in. The right spec for almost every Calgary primary residence; unlocks a 5–15% home-insurance premium discount with most Alberta carriers.
- 03Designer / luxury asphalt (Malarkey Windsor, GAF Camelot II, OC Berkshire, IKO Royal Estate): $7.40–$9.00 per sq ft. On a 30-square roof that is $22,200–$27,000 all-in. Slate/shake-look profiles for inner-city character homes.
- 04Standing-seam metal roof (24-gauge, hidden-fastener): $12–$18 per sq ft. On a 30-square roof that is $36,000–$54,000 all-in. 50-year service life, near-immune to hail at Class 4 ratings, premium resale.
- 05Stone-coated steel (DECRA, Allmet): $13–$17 per sq ft. On a 30-square roof that is $39,000–$51,000 all-in. Shingle-look profile, transferable lifetime warranty.
- 06Cedar shake (Western Red, #1 Blue Label): $14–$22 per sq ft. On a 30-square roof that is $42,000–$66,000 all-in. Character-home spec only — most Calgary insurers now surcharge or refuse cedar without supplemental fire and hail underwriting.
- 07Flat-roof membrane (2-ply SBS torch-on, TPO, EPDM): $9–$14 per sq ft. On a 1,200 sq ft flat section that is $10,800–$16,800 all-in. Used on flat-roof character homes and additions.

What an all-in 2026 Calgary roof quote actually includes
The $15,600–$26,000 range above is comprehensive. If a Calgary quote comes in $4,000–$8,000 lower than ours, almost every time it’s because the cheaper quote is leaving line items off the page — items that will be back-charged as “upgrades” once the crew is on the roof. Here is exactly what should appear on every Calgary new-roof quote.
- 01Full tear-off to the deck on every job. Alberta code allows two layers — we never roof over, and the resale market doesn’t reward roof-overs. Every job is a tear-off.
- 02Deck-rot inspection on every OSB sheet. First four sheets of replacement OSB included free in every Good Roofing Calgary quote. Beyond four sheets, $90/sheet supplied and installed.
- 03Synthetic underlayment (not felt) across the entire deck — sheds water during the tear-off-to-shingle gap and is rated for 6 months of UV.
- 04Ice-and-water shield at every eave (24″ past the interior wall line per amended Alberta code), in every valley, around every penetration (chimney, plumbing stack, skylight), and at every rake on roofs above 8/12 pitch.
- 05Starter strip + drip edge at every eave and rake. Skipping starter strip is the #1 cause of Chinook-wind blow-off on Calgary asphalt roofs.
- 06All-new flashings — step flashing at every sidewall, counter-flashing at brick and stucco, lead boots on every plumbing stack, new bath/kitchen exhaust hoods if the existing ones are dented.
- 07Ridge venting (continuous) matched to balanced soffit intake. Re-using an old box vent or a turtle vent layout voids most shingle warranties.
- 08Magnet sweep + jobsite cleanup across the lawn and driveway every evening of the install. Written workmanship warranty issued the day the job is complete.

Cost drivers — what makes your Calgary new roof more (or less)
Two homes on the same Calgary street can re-roof for $4,000–$10,000 apart. Here are the variables that move the price, in order of impact.
- 01Field square footage — the biggest single driver. Most Calgary single-family roofs are 22–38 squares (2,200–3,800 sq ft). Two-storey homes have less roof for the same floor plan than bungalows.
- 02Roof pitch. Below 6/12 is walkable and at standard rate. 6/12–8/12 adds $0.40–$0.80 per sq ft for safety setup. 8/12–10/12 adds $0.80–$1.20 per sq ft. 10/12+ requires scaffolding or roof brackets — typically $1.50–$2.50 per sq ft surcharge.
- 03Shingle class (Class 3 vs. Class 4). Class 4 impact-rated SBS-modified asphalt adds roughly $0.90 per sq ft over Class 3 — about $2,700 on a 30-square roof — and unlocks insurance premium discounts plus future deductible-only re-roofs.
- 04Penetrations and complexity. Each additional plumbing stack, skylight, chimney, dormer, valley, or sidewall step-flash adds time. A clean rectangular bungalow re-roofs faster than a multi-gable two-storey with three dormers and four valleys.
- 05Deck rot. Discovered only after tear-off. Calgary homes built before 1995 routinely show 2–8 sheets of OSB or plank rot, especially at eaves and valleys. First 4 sheets free in our quotes; beyond, $90/sheet.
- 06Insulation / ventilation balancing. Re-balancing attic ventilation (correct intake/exhaust ratio) is the difference between a 30-year roof and a 17-year roof. We include this. Many low-quote competitors skip it.
- 07Tear-off layer count. If the existing roof is already two layers (legal in Alberta, no longer code-compliant), disposal adds $0.30–$0.50 per sq ft.
- 08Access & staging. Tight-driveway Calgary inner-city homes (Hounsfield Heights, Bridgeland, Inglewood, Altadore) sometimes require dumpster placement on the street and a no-parking permit ($85/day).
- 09Hail-damage insurance claim coverage. If hail damage is documented and approved, your out-of-pocket drops to your deductible — typically $1,000–$2,500 on a flat-deductible policy, more if you have a percentage hail deductible. We’ve recovered ${FACTS.metrics.hailClaimsRecovered} on Calgary claims.

How to compare Calgary new-roof quotes apples-to-apples
Calgary’s roofing market is full of mismatched quotes — one comes in at $11,000 and another at $19,000 and the homeowner has no idea why. Almost every time, the spread is because line items are missing, not because the cheap quote is “a better deal.” Here is the 7-question checklist that flattens any two Calgary quotes onto the same page so you can compare what you’re actually buying.
- 01Is it a fixed written quote or a “starting at” number? Good Roofing never quotes “starting at.” Every Calgary quote is fixed, written, and signed. If a competitor quotes a range, ask for the top of it in writing.
- 02Class 3 or Class 4 shingle? Get the specific product name (e.g. “Malarkey Vista AR Class 4” — not “30-year shingles”).
- 03Full tear-off or roof-over? Tear-off is the only acceptable answer in Calgary.
- 04How much deck-rot replacement is included? If the answer is “billed extra at $X/sheet,” the cheap quote is incomplete by hundreds to thousands.
- 05Ice-and-water shield — at eaves only, or eaves + valleys + penetrations + rakes? The right answer is all four locations. Skipping any voids most manufacturer warranties.
- 06Ridge venting included and balanced to soffit intake? Not optional in Calgary’s freeze-thaw climate.
- 07Workmanship warranty in years — and is it transferable? Our standard is 10-year transferable. The Calgary market norm is 2–5 years, often non-transferable.

Insurance vs. out-of-pocket — when your Calgary new roof might cost just your deductible
If your Calgary roof has documented hail or wind damage from a covered storm, your home insurance typically pays for the full re-roof and you only pay your deductible. On a flat-deductible policy that is $1,000–$2,500 out of pocket on a $20,000+ re-roof. On a percentage hail deductible — increasingly common in Calgary’s hail belt since 2023 — a 2% deductible on a $750,000 home is $15,000 out of pocket, which changes the math. Good Roofing handles the claim end-to-end: free drone inspection, written damage report inside 24 hours, adjuster meeting on the roof, scope supplement if the initial estimate is light, and certificate of completion to release the depreciation holdback. We’ve recovered $14M+ on Calgary hail claims since 2014 working with Intact Insurance / belairdirect, Aviva Canada, TD Insurance, Co-operators, Wawanesa Mutual and every other major Alberta carrier. The single best move a Calgary homeowner can make is upgrading to Class 4 impact-rated shingles at the next re-roof — UL 2218 Class 4 cuts your wind/hail insurance premium 5–15%, often returns you to a flat deductible at renewal, and turns the next hailstorm into a deductible-only outcome instead of an out-of-pocket fight.
