If you own a detached or semi-detached home in Toronto, sooner or later you will need a new roof. Asphalt shingle roofs in the GTA usually last 15 to 25 years, depending on quality, attic ventilation and how many freeze-thaw winters they face. Here is what a replacement costs in 2026 and how to avoid paying too much.
Typical 2026 prices in Toronto
| Roof type | Typical installed cost |
|---|---|
| Architectural asphalt shingles | about $5.80 to $7.80 per sq ft |
| Detached home, asphalt shingles | about $8,800 to $16,500 |
| Semi or townhouse, asphalt shingles | about $5,800 to $9,200 |
| Standing-seam metal | about $14 to $23 per sq ft |
Large homes with complex rooflines in areas like Rosedale, Forest Hill and Lawrence Park often run $14,000 to $26,000 or more. Simpler roofs in Scarborough or Etobicoke bungalow areas are usually at the lower end. These ranges come from a 2026 Toronto roofing price guide and are a starting point, not a quote.
What pushes the price up
- Rotten decking. If the wood under the shingles is soft, replacing plank decking can add several thousand dollars.
- Multiple layers. Older homes sometimes have two layers of shingles. Tearing off both costs more.
- Steep pitch and height. Steep roofs need more safety equipment and labour.
- Chimneys, skylights and valleys. Each one needs new flashing.
- Ventilation fixes. Poor attic ventilation shortens roof life and can cause ice dams. Adding vents now is cheaper than a second early replacement.
- Street access. On narrow downtown streets, a City permit for the disposal bin adds cost.
Shingles, metal or flat roof?
Architectural asphalt shingles are the standard for GTA houses: good value, many colours and a 25 to 30 year manufacturer rating. Metal costs two to three times more up front but can last 40 years or more and sheds snow well. Flat roofs, common on Toronto row houses, rear additions and garages, use modified bitumen or membrane systems and need a roofer who specializes in them.
How to get a fair quote
- Get at least three written quotes, itemized: tear-off, decking allowance, underlayment, drip edge, flashing, ventilation, shingles, disposal and permits.
- Ask how rotten decking will be priced if they find it. A per-sheet price avoids surprises.
- Check the roofer’s WSIB clearance and liability insurance. If an uninsured worker is hurt on your property, you can be exposed.
- Ask about both warranties: the manufacturer’s on the materials and the roofer’s on the workmanship.
- Book in late spring or early fall if you can. Peak summer and emergency repairs cost more.
Does a new roof help when you sell?
A roof is not a feature buyers pay extra for, but an old one is something they deduct for. If your roof is near the end of its life, a buyer’s inspector will flag it and the buyer will ask for a price reduction that often exceeds the actual cost of the work. Replacing it before listing, and handing over the invoice and warranty, usually protects your price. See our guides on improvements that pay back and selling for top dollar.
If you are buying, ask the seller for the age of the roof and any receipts, and make sure your inspection covers it. Our inspection checklist explains what to look for.
