Roof Replacement Costs in Canada (2025)

A roof replacement is one of the most significant home maintenance expenses a Canadian homeowner will face. Unlike a kitchen renovation, there's no discretionary element — when your roof needs replacing, it needs replacing. Understanding costs ahead of time lets you plan financing and negotiate confidently with contractors.

Average Roof Replacement Costs in Canada

• Small home (under 1,200 sq ft): $6,000 – $12,000
• Average home (1,500–2,000 sq ft): $100 – $20,000
• Large home (2,500–3,500 sq ft): $18,000 – $35,000
• Complex roof (multiple peaks, dormers): Add 20–40%

Cost by Roofing Material

Asphalt Shingles (Most Common)

Asphalt shingles cover the majority of Canadian homes. Cost depends on the grade:

• 3-tab shingles: $3.50–$5/sq ft installed (lifespan: 15–20 years)
• Architectural/dimensional shingles: $5–$8/sq ft installed (lifespan: 25–30 years)
• Premium/impact-resistant shingles: $8–$12/sq ft installed (lifespan: 30–50 years)

Metal Roofing

• Steel standing seam: $12–$22/sq ft installed
• Corrugated metal panels: $8–$15/sq ft
• Metal tiles: $10–$18/sq ft
• Lifespan: 40–70 years — best long-term value despite higher upfront cost

Cedar Shakes/Shingles

• $10–$18/sq ft installed
• Lifespan: 20–30 years with maintenance
• Popular in BC and Alberta; requires more maintenance than asphalt

Flat Roofs (EPDM, TPO, Modified Bitumen)

• $5–$15/sq ft installed depending on material
• Common in condos, additions, older urban homes
• Lifespan: 15–25 years

What's Included in a Roof Replacement Quote

A complete roof replacement should include:

• Tear-off and disposal of existing shingles
• Inspection and replacement of damaged decking (OSB or plywood)
• Ice and water shield membrane (required by code in Canada)
• Synthetic underlayment
• New shingles, ridge caps, and starter strips
• Flashing replacement (around chimneys, vents, valleys)
• Drip edge installation
• Cleanup and haul-away

Additional Costs to Budget For

• Decking replacement: $2–$5/sq ft if OSB or plywood is rotted or damaged
• Chimney flashing: $400–$1,500 if the chimney flashing needs complete replacement
• Soffit and fascia: $1,500–$6,000 if these are deteriorated alongside the roof
• Skylight replacement/resealing: $300–$2,000 per skylight
• Permit (some municipalities require it): $200–$600

Roof Replacement Costs by Province

Labour costs drive significant regional variation:

• BC: $12,000–$22,000 average (premium labour market)
• Ontario: $100–$20,000 average
• Alberta: $9,000–$18,000
• Quebec: $9,000–$17,000
• Atlantic Canada: $7,000–$14,000
• Prairie provinces: $8,000–$16,000

When to Replace vs. Repair

Repair (not replace) if:

• Roof is under 15 years old and has isolated damage
• Less than 30% of shingles are damaged
• No widespread granule loss

Replace when:

• Roof is 20+ years old (asphalt) or 30+ (cedar)
• Multiple repairs have been done previously
• Significant granule loss or widespread cracking
• Interior water damage or moss growth over large areas

Financing a Roof Replacement

Since roof replacement is often urgent and unplanned, financing options matter:

• HELOC: Best rate if you have equity — can be approved quickly
• Personal loan: Faster approval, no equity required — 8%–15%
• Home equity loan: Good for larger replacements on complex homes
• Manufacturer financing: Some contractors offer deferred payment or financing through lenders like Financeit

For an urgent replacement, a personal loan is often the fastest path. If you can wait a few weeks, a HELOC will save considerably on interest for a $15,000–$20,000 project.
