How much does roofing cost in Ottawa?
Most Canadian homeowners spend $12,000-$15,000 to replace an asphalt shingle roof on a typical detached home in 2026 - full tear-off, new shingles, underlayment, flashing and cleanup, or roughly $6-$8 per square foot. Smaller or simpler roofs start near $8,000; large or steep roofs run up to $18,000, and a premium metal or standing-seam roof reaches $25,000-$35,000. Isolated repairs are far cheaper - about $300-$400 to replace blown-off shingles and $600-$900 for a typical leak.
In Ottawa, ON, typical quotes tend to track the Canadian average, so the table below shows these national figures unchanged.
What moves the price: The low end is a spot repair or a small, simple asphalt roof; the top end is a large or steep roof, with premium metal or standing-seam systems costing the most.
| Project | Typical cost in Ottawa |
|---|---|
| Full asphalt shingle roof replacement - typical single-family house (tear-off + new shingles, all-in) | $12,000-$15,000 $8,000 to $18,000 per project |
| Asphalt shingle roofing, installed (all-in, by roof area) | $6-$8 $4.50 to $10 per sq ft |
| Asphalt shingle roofing, installed (priced by roofing "square" = 100 sq ft) | $600-$900 $450 to $1,100 per square (100 sq ft) |
| Flat roof replacement - EPDM rubber or TPO membrane (residential) | $8-$11 $6 to $14 per sq ft |
| Metal roof replacement - steel / standing seam (typical house) | $25,000-$35,000 $18,000 to $45,000 per project |

What changes the price of roofing in Ottawa
- Roof size and shape - roofing is priced per 100 sq ft "square," so a bigger footprint, more corners, valleys, dormers and hips all push the total up directly.
- Shingle grade - basic 3-tab is the cheapest, architectural/laminated is the common mid-tier, and designer/luxury shingles cost the most per square.
- Roof pitch and access - steep, tall or hard-to-reach roofs need more safety setup and slower work, and labour is 50-70% of a typical roofing bill.
- Tear-off and disposal - stripping and dumping old shingles (especially two or more existing layers) adds cost versus going over the old roof.
- Hidden damage found once the roof is opened - rotted plywood decking (about $75-$130 per sheet), soft spots, and worn vents or flashing add to the final number.
- Location - big-city labour demand pushes Toronto (GTA) and Vancouver quotes noticeably above small-town pricing.
How roofing prices vary across Canada
Big cities cost more, and it is almost entirely a labour effect. Toronto, the GTA and Metro Vancouver roofing quotes run roughly 15-25% above the national and small-town average. Other major metros - Calgary, Edmonton, Ottawa, Montreal - sit closer to par, roughly national to 10% above. Small-town and rural pricing is at or slightly below the national midpoint.

Can I put new shingles over the old ones instead of tearing off?
Sometimes. Going over one existing layer saves on tear-off and disposal, but most roofers recommend a full tear-off so they can inspect and replace any damaged decking underneath, and many building codes cap you at two total layers. A tear-off costs a bit more up front but usually lasts longer.
How much does it cost to replace an asphalt shingle roof in Canada?
Most homeowners spend $8,000 to $18,000 for a full tear-off and new shingles on a typical single-family home in 2026, usually landing around $12,000-$15,000. That works out to roughly $4.50-$10 per square foot, or about $450-$1,100 per roofing "square" (100 sq ft) installed.
What does a flat roof cost compared to shingles?
Flat roof membranes - EPDM rubber or TPO - generally run $6-$14 per square foot installed. A typical residential flat roof section lands around $4,000-$12,000 depending on size, insulation, and how many vents or drains need flashing around them.
