What this calculator estimates

This calculator quotes the all-in replacement price for a residential eavestrough and downspout system in 2026 Canadian dollars. Sales tax (HST/GST/PST) varies by province and is shown as a separate line. Replacement always includes tear-off, fascia inspection, and almost always drip edge replacement.

  • Tear-off — labour and dump fees to remove existing eavestrough and downspouts. Always included.
  • Fascia repair — new fascia board material and labour where the existing wood has rotted from chronic overflow or ice damming. The condition selector estimates 0%, 15%, or 40% of the run.
  • Drip edge / ice-and-water shield — new drip edge or ice-shield extension where the old material is bent, rusted, or attached to the old eavestrough.
  • Eavestrough material — linear-foot cost of new seamless eavestrough, varying by profile (K-style, half-round, fascia, box) and material (aluminum, galvanized steel, PVC, copper, zinc).
  • Downspouts — material cost based on quantity and run length.
  • Accessories — hangers (every 24 inches in heavy-snow zones per NBC), sealant, end caps, elbows, miter fittings.
  • Install labour — crew hours at the regional rate, with multipliers for profile complexity, building height, and access.
  • Leaf guards — micro-mesh, hood, or foam add-on per linear foot.
  • Permit — most provinces don’t require permits for eavestrough replacement, but check with your municipality if connecting to municipal storm sewer.

A minimum job floor of CAD $880 applies to most Canadian replacement projects.

How to use it

  1. Measure your linear length. Sum every eave where eavestrough runs. The standard rectangular bungalow is typically 140–170 feet; a two-storey home with side-extensions runs 200–280 feet.
  2. Count corners and miters. Each inside or outside corner adds 30 minutes of crew time and a $14–$24 fitting.
  3. Pick the new profile and material. K-style aluminum is the Canadian default. Half-round matches heritage homes. Copper for premium applications.
  4. Set the size. 5-inch K-style is the residential standard. Bump to 6-inch for steep pitches, large drainage areas, or ice-prone regions.
  5. Specify downspouts. A common rule per NBC 2020: one downspout per 35–40 feet of run, or one per 600 square feet of drainage area.
  6. Set fascia condition honestly. “Sound” assumes recent inspection confirmed no rot. “Partial” (15% replaced) is typical on a 15-to-25-year-old system. “Extensive” (40% replaced) is common when chronic ice-damming has saturated the fascia for years.
  7. Toggle drip edge replacement. Default is on — most replacements include drip edge swap.
  8. Set storey count and access. Three-storey homes, scaffolded jobs, and properties with no driveway ladder access add 15–25% to labour.

Pricing assumes a two-storey home, 6 downspouts, partial fascia repair, drip edge replacement, standard daytime labour, and Southern Ontario / GTA labour rates. BC Lower Mainland and Calgary rates run 5–10% higher; Atlantic Canada runs 10–15% lower. Quebec includes QST. Single-storey deduct 8–10%. Three-storey or full scaffold add 20–25%.

Cost drivers

Fascia repair extent. Biggest variable in Canadian replacement projects, especially after a winter with significant ice damming. Sound fascia means $0 added. Partial rot (15%) typically adds $300–$700. Extensive rot (40%) adds $900–$2,200 — at which point you should also be asking your contractor about soffit and ice-and-water shield extension up the roof deck.

Ice-damming exposure. Homes in ice-dam-prone regions (Atlantic provinces, Northern Ontario, BC interior) should specify 0.027-inch heavy-gauge aluminum minimum, 24-inch hanger spacing per NBC 2020, and ice-and-water shield extending 24 inches inside the warm wall line per NBC 9.26.5. The premium versus standard spec is $400–$900 on a 180-foot replacement.

Snow load on eavestrough. Heavy snow accumulation can pull eavestrough off poorly-anchored fascia. Replacement projects in heavy-snow zones (CRCA Snow Load Zone 4+) should include snow guards above the eavestrough — adds $8–$14 per foot installed.

Material gauge and thickness. Builder-grade 0.025-inch aluminum is the bottom of the seamless market and not recommended for ice-prone Canadian climates. 0.027-inch is the residential default; 0.032-inch heavy-gauge is recommended for hail-prone Prairie provinces.

Profile complexity. Half-round costs 15–25% more than K-style. Box and fascia profiles add 20–30% — common on Quebec heritage homes.

Storey height and access. Two-storey adds 10% labour over single-storey; three-storey adds 25%. Full scaffold rather than ladder access can double access overhead.

Per-locale code and standards

Canadian eavestrough replacement is governed by:

  • National Building Code of Canada (NBC) 2020 Section 9.26.18 — eavestroughs and downspouts. Minimum 5-inch K-style or equivalent capacity for residential.
  • NBC 9.26.5 — ice-and-water shield extension at eaves: 24 inches minimum inside the warm wall line in unheated and conditioned spaces.
  • CSA A123.3 — asphalt-saturated organic felt for steep-slope roofing (related to drip-edge underlayment).
  • CSA Z259.10 — full body harness and lanyard requirements for working at heights.
  • CRCA Roofing Specifications — best-practice details for eavestrough installation, including hanger spacing, slope (1:600 minimum), and downspout outlet sizing.
  • Provincial building codes — Ontario Building Code, Quebec Building Code, Alberta Building Code, BC Building Code all reference NBC 2020 with provincial amendments.

Most provinces don’t require permits for eavestrough replacement. Toronto, Vancouver, and Montreal historic districts may require heritage approval for cast iron or copper material substitution.

Repair vs full replacement decision matrix

Replace the whole system when:

  • Multiple leaks, joints failing, or seam separation across more than 30% of run
  • Visible rust, corrosion-through, or paint failure across multiple sections
  • Ice-dam-driven fascia rot in more than two rafter bays
  • The system is over 20 years old (industry service-life median for aluminum in Canadian climates)

Repair (not replace) when:

  • Damage is localized to one or two sections
  • Hangers are sound and fascia is dry
  • The eavestrough system is under 12 years old

Avoiding scams and overcharging

After significant storm or ice-damming events, itinerant “storm chaser” eavestrough contractors door-knock affected neighbourhoods, particularly in the GTA, Hamilton, and London ON suburbs. Red flags:

  • Unsolicited “I noticed your eavestrough” doorstep approaches
  • Pressure to sign before you’ve reviewed a written quote
  • No provincial trade licence or municipal business licence
  • Cash-only or no-HST offers (legitimate contractors charge sales tax)
  • “Lifetime warranty” without specifying transferability and company longevity

Insist on a written estimate with material gauge and brand, hanger spacing, downspout count, fascia repair line item with per-foot pricing, and a written workmanship warranty (5 years is CRCA standard).

Frequently asked questions

How much does eavestrough replacement cost in Canada in 2026?
Most Canadian homeowners pay $2,200 to $5,400 (CAD, including HST/GST/PST as applicable) to replace eavestroughs in 2026, with a typical project landing around $3,600 for 180 feet of seamless 5-inch K-style aluminum on a two-storey home with six downspouts, partial fascia repair, drip edge replacement, and moderate access. Replacement runs 35–55% more than first-fit installation because of tear-off labour, dump fees, and the high probability of fascia rot discovered after the old eavestrough comes down. Copper or zinc systems push the bill to $7,500–$15,000+. Source: 2026 HomeStars and Renomii data plus CRCA member quotes.
Why is eavestrough replacement more expensive than a first-time install?
Three reasons. First, tear-off and dump fees add 4–6 hours of crew time and $50–$110 in disposal. Second, replacement projects routinely uncover hidden fascia rot — 15–40% of the run typically needs repair before new eavestrough can mount, adding $300–$1,800. Third, drip edge, ice-and-water shield, and starter strips often need replacement at the same time. Budget 1.4× to 1.6× a first-fit number from a similar Canadian property.
Should I just repair instead of replace?
Repair when damage is localized — one or two leaking sections, a few broken hangers, or a single ice-dam-pulled run. Replace the whole system when more than 30% of joints leak, the eavestrough sags between hangers, you see rust streaks or paint failure on multiple sections, fascia damage extends beyond two rafter bays, or the system is over 20 years old. In Canadian climates, ice-damming damage shortens average system life — most aluminum systems are replaced at 18–25 years.
What's included in a typical Canadian eavestrough replacement?
A full replacement bid should include: tear-off and dump disposal of existing eavestrough and downspouts, inspection and replacement of fascia boards where rotted (typically billed per linear foot), new seamless eavestrough formed on-site, new downspouts and elbows, hangers at 24-inch spacing in heavy-snow zones (NBC requirement), end caps and miter cuts, drip edge or ice-and-water shield extension where applicable, sealant at all joints, splash blocks or downspout extensions to grade, and clean-up. HST/GST/PST applies depending on province. Always insist on a written line-item proposal — not a single lump sum.
How long does eavestrough replacement take?
A typical residential job (180–220 feet, 4–6 downspouts, two-storey, partial fascia repair) takes a 2-person crew 1–2 calendar days. Day one: tear-off, fascia inspection and repair, drip edge replacement. Day two: form and install new eavestrough, hang downspouts, sealant cure, clean-up. Single-storey homes with sound fascia complete in one long day. Three-storey homes with full scaffold or extensive fascia rot run 3–4 days. Working-at-heights training (CSA Z259.10) is mandatory across most provinces.
Does home insurance cover eavestrough replacement?
Home insurance covers eavestrough replacement when damage results from a covered peril — wind, hail, ice damming with proven backup, fallen tree, vehicle impact. Wear-and-tear, age-related failure, rust, and clog-related fascia rot are excluded. Document storm damage with photos within 48 hours, file the claim within the policy's reporting window (typically 30 days), and request a CRCA member's report. Ice-dam coverage varies between insurers — some require evidence the homeowner kept gutters clean and snow loads cleared. Review your policy's water-damage and ice-dam endorsements carefully before filing.
Should I replace the fascia at the same time?
Yes when the fascia shows rot, water staining, or soft spots when probed. Replacing fascia separately later is twice as expensive because the new eavestrough has to come back off. Standard practice: tear off the old eavestrough, probe every linear foot of fascia with an awl, replace every section softer than the surrounding wood. Pine or hemlock fascia at $9–$18 per linear foot installed; PVC composite at $16–$26 per linear foot installed for a 50-year service life. The composite premium pays back over the next eavestrough cycle and resists ice-dam moisture.
Should I upsize when I replace?
Consider it if your old eavestrough overflowed during heavy rain or spring melt, your roof drainage area exceeds 2,000 square feet per downspout, you have valleys feeding the run, your roof pitch is above 8/12, you live in an area with frequent ice-damming (Atlantic provinces, Northern Ontario, BC interior). Going from 5-inch to 6-inch K-style adds about 18% to material cost but 70% to capacity. NBC 2020 references rainfall intensity in Appendix C — use your provincial rainfall map for sizing. The retrofit window is now — making the change later requires another tear-off.
Are heat cables a substitute for replacement?
Heat cables ($150–$400 installed per 100 feet) prevent ice damming but don't address an aging eavestrough that's structurally compromised. They're a complement, not a replacement. If your existing eavestrough is sound but you have recurring ice damming, heat cables in the gutter and 3 feet up the roof edge are a $400–$800 fix. If the eavestrough is sagging, leaking at joints, or mismatched from years of patch repairs, replace the eavestrough first and consider heat cables as an add-on.
