What this calculator estimates

This calculator quotes the all-in installed price for a residential skylight installation in 2026 Canadian dollars. The bill itemizes the line items a CRCA-member roofer or licensed contractor writes:

  • Skylight unit — the manufactured glazed assembly, priced by size and type. VELUX, Fakro, Columbia Skylights, and major-brand units at 2026 Canadian distributor pricing.
  • Flashing kit — manufacturer-spec flashing for asphalt, metal, tile or membrane. Required for warranty.
  • Framing / cut-in — for retrofit, this includes sistering rafters or modifying trusses (always engineered review for truss modifications), upper and lower headers, and re-sheathing.
  • Drywall / shaft finish — closing the interior ceiling around the opening, building an insulated shaft, taping, mudding and painting. Vapor barrier and air seal at all penetrations is critical in Canadian climate zones to prevent condensation.
  • Add-ons — manual or motorized blinds, rain sensor for vented units, smart-home hub, new 120V electrical run.
  • Permit — typical municipal building permit fee.
  • Disposal — debris haul-away and dump fee.
  • Weekend / after-hours premium — 25% surcharge.

A minimum service-call floor of $455 applies in most Canadian metros — even a single sun tunnel install carries this floor because mobilizing a 2-person crew, fall arrest gear, and ladders is the dominant cost.

How to use it

  1. Count the units — total skylights installed in one mobilization.
  2. Pick a size. Small around 22x22 inches (a sun tunnel or VELUX C04). Medium is 22x46 inches (VELUX FS C06 — most common Canadian residential size). Large is 30x46 inches. Oversize is anything above 44 inches in either dimension.
  3. Pick type. Fixed for stairwells and high ceilings. Vented manual for kitchens and bathrooms with reachable cranks. Vented electric or solar for premium installs. Sun tunnel for closets, windowless ensuites and corridors.
  4. Pick glazing. Triple-glazed argon-filled Low-E is the NBC-compliant 2026 default for most of Canada. Laminated safety glass is mandatory over baths and beds per OBC 9.6 and parallel codes. Tempered Low-E is the impact-rated coastal spec.
  5. Pick roof material. Asphalt shingle is the cost-neutral baseline. Standing-seam metal adds 20%. Clay or concrete tile adds 45%. Natural slate (rare outside heritage homes in Quebec) adds 70%. Flat membrane adds 30%.
  6. Pick work scope. Retrofit is the most common scenario — includes framing, flashing and drywall. New construction is significantly cheaper.
  7. Set storey count. Labour multiplier is 1.0x for single, 1.18x for two, 1.42x for three or more.
  8. Toggle add-ons. Blinds, rain sensor, smart hub, new 120V run, permit, disposal, weekend premium each adjust the total.

Typical 2026 Canadian skylight installation cost ranges

These ranges reflect 2026 metro pricing from HomeStars cost guides, Renomii averages, CRCA member surveys, and direct quotes from VELUX-certified installers in major Canadian metros.

Configuration (asphalt shingle, retrofit, single storey)2026 installed price
Sun tunnel (10-14 in)$595 – $1,180
Small fixed skylight (22x22)$925 – $1,720
Medium fixed (22x46)$1,560 – $3,025
Medium vented manual (22x46)$2,025 – $3,725
Medium vented electric / solar (22x46)$2,775 – $4,860
Large fixed (30x46)$2,315 – $4,485
Oversize / custom (44x46+)$3,965 – $8,975

Add 45% over the asphalt baseline for clay tile. Add 70% for natural slate. Add 20% for standing-seam metal. Add 30% for flat membrane.

Cost drivers

Unit type and size. Unit cost is 40-55% of the total. Fixed → vented manual adds 35%, fixed → vented electric adds 95%, fixed → solar-vented adds 70%.

Roof material. Asphalt shingle is fastest. Standing-seam metal (Roofmart, MAC, Vicwest) needs a specialty flashing profile. Clay tile and concrete tile (uncommon outside BC) require tile cutting and re-bedding — 3-5 extra labour hours per unit.

Retrofit vs new construction. Cutting a new opening requires stripping shingles back 18-24 inches on all four sides, cutting sheathing without nicking trusses (always engineered for truss-roof homes), doubling cut framing members, and adding upper/lower headers. New construction skips this. New construction is 35-45% cheaper.

Drywall / shaft finish. A skylight in a cathedral ceiling needs no shaft. A skylight in a flat ceiling with attic above needs a 24-60 inch shaft, framed, insulated to attic R-value (R-60 to R-70 in Zone 7-8), vapor-barriered, drywalled and painted. The shaft alone adds $425-$1,250.

120V electrical run. A vented electric skylight needs 120V power. New runs from the panel require licensed electrician time at $85-$140/hr depending on metro.

Ice and water shield (critical in Canadian climates). Manufacturer specs require minimum 24 inches of ice and water shield around skylights in zones with snow load. NBC 9.26.5 requires eave protection minimum 36 inches past the warm-side line of the exterior wall. Without it, ice-dam-driven head leaks are inevitable.

Geographic spread. Toronto, Vancouver, Calgary and Montreal metros sit close to the national median. Atlantic Canada (Halifax, St. John’s) runs 5-10% below median. Yellowknife, Whitehorse and remote-fly-in locations carry 50-100% mobilization premiums.

Canadian codes and standards

Skylight installation in Canada is governed by:

  • NBC 9.7 — Windows, doors and skylights. Performance and installation requirements.
  • NBC 9.27 — Cladding. Flashing details around openings.
  • NBC 9.36 — Energy efficiency for housing. U-factor and SHGC requirements by climate zone.
  • OBC, QCC, BCBC, ABC etc. — Provincial codes referencing NBC with amendments.
  • CAN/CSA A440-22 / NAFS-22 — North American Fenestration Standard, harmonized US-Canada product certification.
  • CAN/CSA A440.4 — Window, door and skylight installation.
  • CSA F326 — Residential mechanical ventilation systems.
  • ENERGY STAR Canada — voluntary high-performance window/skylight certification, referenced by provincial rebate programs.

Climate-zone considerations

Zone 4 (Vancouver, Victoria, Lower Mainland) — mildest Canadian climate. Standard NBC 9.36 U-factor 2.7, double-glazed Low-E acceptable. Rain protection is the dominant flashing concern.

Zone 5 (Toronto, Hamilton, Niagara, southern Ontario) — U-factor 2.4. Argon-filled double Low-E is the rational spec. Ice and water shield at eaves and around skylights.

Zone 6 (Ottawa, Montreal, Quebec City suburbs) — U-factor 2.1. Triple-glazed Low-E is the baseline. Ice & water shield 36 inches past warm-side line.

Zone 7A (Edmonton, Calgary, Winnipeg, Saskatoon, Quebec City core) — U-factor 1.9. Triple-glazed argon-filled Low-E with warm-edge spacer. Ice and water shield at eaves, valleys, and around all penetrations.

Zone 7B / 8 (Yellowknife, far north) — U-factor 1.6 or better. Triple-glazed with krypton fill is sometimes specified. Skylight installations in these zones are typically restricted to the short summer window.

Diagnostic step-by-step (before quoting)

  1. Measure the ceiling location and verify attic space. Vaulted ceilings under finished rooms add complexity.
  2. Check the truss / rafter type. Stick-framed rafters at 16 or 24 inch centres are simple to trim. Engineered trusses CANNOT be cut without an engineer’s approval and a sister-truss design.
  3. Check the roof pitch. Below 14° most skylights need a curb. Below 3° this is a low-slope detail.
  4. Note the roof age and condition. A 20+ year old asphalt roof is a poor candidate.
  5. Identify HVAC, plumbing and electrical above the ceiling.
  6. Check the eave protection zone — most Canadian municipalities require minimum 36 inches of ice and water shield past the warm-side wall line.

Avoiding overcharging

The skylight install market has a small but persistent door-knocker problem after wind or hail events. Red flags:

  • “Storm damage” claims after routine winter weather.
  • Pressure to sign before written, itemized quote.
  • Cash-only or wire-transfer demands.
  • Refusal to provide a licensed contractor number or WSIB / WCB proof.
  • Bundling a $2,200 skylight install into a $15,000 full re-roof at the first visit.
  • Substitute flashing kits — never accept a non-manufacturer flashing.

Insist on a written estimate that itemizes the unit model, size, type, glazing spec, manufacturer flashing kit part number, framing scope, finish scope, permit responsibility, and disposal. Get licence, WSIB/WCB and liability insurance proof before any work begins.

Frequently asked questions

How much does a skylight cost installed in Canada in 2026?
Most Canadian homeowners pay $1,850 to $4,250 to install a medium fixed skylight on an asphalt shingle roof in 2026, with a typical job (one VELUX FS 22x46 inch fixed unit, triple-glazed Low-E argon-filled to NBC 9.36 cold-climate spec, retrofit cut, single-storey home in Ontario or Quebec, permit and disposal) landing around $2,180 fully installed. Stepping to vented manual adds CAD $480-$760, vented electric or solar adds CAD $1,150-$1,750 over fixed, and natural slate adds 65-70% to the labour. Source: 2026 HomeStars cost guide, Renomii 2026 averages, CRCA contractor surveys, and direct quotes from Roofmart-affiliated and VELUX-certified installers in Toronto, Montreal, Vancouver, Calgary, Edmonton, Ottawa, Halifax and Winnipeg.
Do I need a permit for a skylight in Canada?
Yes in every Canadian province. The National Building Code (NBC) and provincial building codes (OBC in Ontario, QCC in Quebec, BCBC in BC, ABC in Alberta etc.) require a permit for any new roof opening that cuts a structural framing member. Permit fees typically run $150-$425 in residential markets and require submittal of a framing detail showing the trimmed rough opening. Replacing an existing skylight with a same-size unit in the same opening may be treated as a repair in some municipalities (Toronto, Montreal) but most municipal permit offices require a permit if framing or sheathing is touched. Sun tunnels with shaft diameters under 14 inches typically don't cut framing members in standard truss spacing and are commonly exempt — confirm with your municipal permits office.
What is the NBC 9.36 / cold-climate skylight requirement?
NBC 9.36 Energy Efficiency requires maximum U-factors for fenestration including skylights, varying by climate zone (defined by Heating Degree Days). In Zone 4 (5,000 HDD or less — Vancouver, Victoria) maximum U-factor is 2.7 W/m²K. In Zone 5 (5,000-6,000 HDD — Toronto, Hamilton) it is 2.4. In Zone 6 (6,000-7,000 HDD — Ottawa, Montreal) it is 2.1. In Zone 7A (7,000-8,000 HDD — Quebec City, Winnipeg, Edmonton, Calgary) it is 1.9. In Zone 7B/8 (above 8,000 HDD — Saskatoon, Yellowknife, far north) it is 1.6. Argon-filled triple-glazed Low-E is required to hit Zone 7 numbers — VELUX 70 Q and FAKRO FYP-V are typical NBC-compliant specs. ENERGY STAR Most Efficient certified skylights typically exceed NBC requirements by 15-20%.
What is the difference between a fixed, vented and sun tunnel skylight?
A fixed skylight is a sealed glazed unit that does not open — cheapest and most reliable, ideal for stairwells, hallways and high ceilings. A vented skylight opens to allow hot summer air to escape, rated for kitchens, bathrooms and rooms where moisture removal matters. Manual crank versions add 35% to the unit cost, electric or solar-powered versions add 95%. A sun tunnel (Sun Tunnel, Solatube) is a 10-14 inch rigid or flexible reflective tube that pipes daylight from a small dome on the roof through the attic into a ceiling diffuser — 50-60% the installed cost of a fixed skylight, ideal for closets, windowless ensuites and corridors where a full skylight would be structurally complex or condensation-prone.
Can I install a skylight myself in Canada?
A sun tunnel is a reasonable DIY for a confident homeowner — kit comes with flashing flange, reflective tube and ceiling diffuser. Plan 6-10 hours and CAD $395-$895 in materials. A traditional fixed or vented skylight is NOT DIY-friendly: framing a trimmed rough opening requires doubling rafters or sistering trusses (always engineered review for truss modifications), the flashing kit must interleave precisely with shingle courses, and the interior shaft drywall is interior trade work. Failure rate for DIY skylight installs exceeds 30% in the first year. For energy efficiency permit compliance the installer must work with the municipality energy assessor — DIY installs typically lose the warranty and may flag the home's NRCan EnerGuide rating downward.
Are skylights energy efficient in Canada?
A modern argon-filled triple-glazed Low-E skylight rated to U-factor 1.6 W/m²K is comparable to a premium triple-glazed wall window. Properly oriented and shaded, the energy penalty in heating-dominated Canadian climates is small, and direct south-facing units can be net energy-positive in winter (passive solar gain through low-SHGC Low-E glazing). NRCan's residential building modelling shows that one well-specified skylight per 250 sq ft of floor area in a Zone 5 climate reduces lighting load by 8-12% annually with no measurable heating penalty. ENERGY STAR Most Efficient skylights qualify for provincial rebates in many provinces (Greener Homes, Enbridge HER+, Hydro-Québec Renoclimat).
What is the typical skylight lifespan and warranty in Canada?
VELUX gives a 10-year warranty on the unit and 20 years on the glazing seal. FAKRO matches that. Realistic service life of an aluminum-clad pine-frame skylight installed to NBC and the manufacturer's spec is 25-30 years before the glazing seal fails or the gasket degrades. Acrylic dome skylights — still common in some Quebec and Maritimes housing stock — yellow and craze over 12-18 years and should be planned as a periodic replacement. The flashing kit, when matched to the roof material, matches the roof system life (25-30 years on asphalt, 40+ on metal). The most common premature failure in Canadian climates is ice-dam-driven head leak — install adequate eave protection (ice & water shield minimum 24 inches past the warm-side line) to prevent.
How long does skylight installation take in Canadian conditions?
A single retrofit skylight on an existing asphalt shingle roof takes 6-10 hours on the roof plus 4-8 hours of interior drywall — typically 1.5 days from the homeowner's perspective in good weather. Winter installs (below freezing) take 30-50% longer because adhesives and sealants must be conditioned to room temperature before application and snow must be cleared from the work zone. Sun tunnels install in 3-5 hours. Multiple skylights on the same slope share mobilization. Most reputable Canadian installers do not install skylights between mid-November and early March in zones 6-8 — they restrict to repair-only winter work to avoid cold-glue and ice-dam complications during the install window.
