How much does a roof replacement cost in Quebec in 2026?
Replacing an asphalt shingle roof in Quebec usually costs $5.50 to $9 per sq ft of roof, or about $7,000 to $18,000 before taxes for a single-family home. A metal roof costs roughly twice as much but lasts much longer. Pitch, roof shape and the condition of the decking explain most of the gaps between quotes.
Quebec price ranges in 2026
Quebec market estimates, updated October 2026, before taxes (GST and QST extra). These are not guaranteed prices: costs vary by region, building and materials, and only a written quote based on your project gives an actual price.
| Roof type | Price per sq ft of roof | Typical budget (single-family home) |
|---|---|---|
| Asphalt shingles (20 to 30-year lifespan) | $5.50 – $9 | $7,000 – $18,000 |
| Steel roofing (40 to 50-year lifespan) | $12 – $20 | $18,000 – $35,000 |
| Flat roof, elastomeric membrane (25 to 35-year lifespan) | $12 – $20 | $10,000 – $22,000 |
| Spot repair (leak, flashing, a few shingles) | — | $500 – $3,000 |
What drives the price
- The actual roof area, larger than the house footprint because of pitch and overhangs.
- Pitch and height: a steep or three-storey roof requires more safety equipment.
- The number of slopes, dormers, chimneys and skylights to work around.
- Replacing damaged decking, often found only during tear-off and billed per sheet.
- Attic ventilation, which must be corrected to protect the new roof.
Mistakes to avoid
- Laying new shingles over old ones: the decking stays hidden and the warranty can suffer.
- Ignoring ventilation: a poorly vented attic leads to ice dams and condensation.
- Comparing quotes without knowing the price per sheet of replaced decking.
- Waiting for a leak in mid-winter, when work is harder and more expensive.
How to get reliable quotes
- Ask for the shingle brand and line, the self-adhesive membrane and the type of underlayment.
- Have the unit price for decking replacement and the estimated number of sheets written down.
- Check the contractor's workmanship warranty, separate from the manufacturer's.
- Check that the contractor holds a valid RBQ licence for this type of work in the Régie du bâtiment du Québec registry.
- Insist on a detailed written quote and compare at least three quotes line by line, not just the total.

How much does a bungalow roof cost in Quebec?
