$8,500 – $18,000
A full asphalt shingle roof replacement for an average Ontario home typically costs $8,500 to $18,000, with the price driven mainly by roof size, pitch, and shingle quality.
On a per-square-foot basis, basic asphalt shingles installed run $4.50 to $8.00 per square foot, while architectural shingles — the most commonly chosen option for their appearance and durability — run $5.50 to $7.50 per square foot. Steeper or more complex roofs, with multiple valleys or dormers, push toward $8.50 to $12.00 per square foot because they take longer to work on safely and generate more waste material.
What actually drives the quote higher
Roof pitch and accessibility matter more than most homeowners expect — a steep roof or one that's hard to get equipment to costs more to work on safely, independent of the materials used. The condition of the decking underneath also matters: if the plywood sheathing has rot or damage once the old shingles come off, replacing sections of it adds cost that's hard to know in advance from the ground.
Material costs have moved recently
Shingle material costs have risen roughly 6 to 8% as of 2026, with architectural shingles now running $95 to $145 per square (100 square feet) at wholesale, up from $85 to $130 previously. This is worth knowing if you're comparing a quote against older pricing you might have seen — a higher number than you expected isn't automatically a sign of a bad quote.
Storm damage moves differently
A quote for storm or wind damage often isn't the same as a planned full replacement — sometimes it's a targeted repair, sometimes insurance is involved, and timelines tend to be faster when a leak is active. If you're dealing with active damage, flag it as urgent when requesting quotes so suppliers can prioritize accordingly.
