Karam RoofingA new roof is one of the bigger investments you'll make in your home — so it's worth understanding what actually drives the price before you get quotes. Here are realistic 2026 ranges for the Greater Toronto Area, what makes the number go up or down, and how to make sure you're comparing quotes fairly.
Typical roof replacement costs in the GTA
Most GTA homeowners pay by the "square" (100 sq ft of roof). These are typical 2026 ranges for a full tear-off and replacement on an average home:
| Roof type | Typical installed cost |
|---|---|
| Asphalt shingle (most common) | $7,000 – $16,000 |
| Premium / architectural shingle | $12,000 – $22,000 |
| Metal roof | $18,000 – $40,000+ |
| Flat roof (EPDM / TPO / modified bitumen) | $9,000 – $25,000 |
Ranges are market estimates for planning — your real price depends on the factors below. A free inspection gives you an exact, written number.
What drives the price
- Roof size & complexity. More square footage, steeper pitch, and lots of valleys, dormers or skylights all add labour.
- Tear-off & deck repair. Removing old layers and replacing any rotted plywood underneath adds to the total.
- Material choice. Basic 3-tab shingle is cheapest; architectural, metal and premium systems cost more but last longer.
- Number of existing layers. Two or three old layers cost more to remove and dispose of.
- Access & height. Two- and three-storey homes need more setup and safety equipment.
- Extras. New flashing, ventilation, ice-&-water shield, eavestroughs and warranties.
Asphalt vs. metal vs. flat — which is right?
Asphalt shingle is the go-to for most GTA homes: affordable, good-looking, and 20–30 years of life. Metal costs more up front but can last 40–70 years and shrugs off snow and ice — a strong long-term value. Flat systems (EPDM, TPO, modified bitumen) are for low-slope and flat sections, common on additions and many Toronto homes. We'll walk you through the trade-offs for your home, budget and how long you plan to stay.
How to get an accurate number (and avoid surprises)
- Get an on-site inspection — not a phone guess. Roof size and hidden deck damage change everything.
- Make sure the quote is itemized: tear-off, materials, flashing, ventilation, disposal and warranty.
- Confirm the roofer is licensed, insured and WSIB-covered.
- Ask about the warranty — both the manufacturer's and the workmanship warranty.
