Karam RoofingA new roof is one of the biggest investments you'll make in your Scarborough home — so it's worth understanding what actually drives the price before you gather quotes. Here are realistic 2026 ranges for Scarborough and the east GTA, what pushes the number up or down on our older housing stock, and how to make sure you're comparing quotes fairly. Not sure you even need a full replacement yet? Start with our Scarborough leak repair cost guide.
Typical roof replacement costs in Scarborough
Most roofs are priced by the "square" (100 sq ft of roof). These are typical 2026 ranges for a full tear-off and replacement on an average Scarborough 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 on-site inspection gives you an exact, written number for your roof.
What drives the price on a Scarborough home
- Roof size & shape. Many Scarborough bungalows (Birch Cliff, Cliffside, Bendale) have smaller, simpler roofs, which can keep the total at the friendlier end. Two-storey homes and complex roofs with dormers, valleys and skylights cost more.
- How many old layers come off. Older Scarborough roofs sometimes carry two or even three layers of old shingles — more to tear off and dispose of means more labour.
- Deck repair. Once the old roof is off, any rotted plywood underneath (common where a leak sat for a while) is replaced — a variable that only a real inspection reveals.
- Flat sections. Rear additions and garages with flat roofs are a different system (EPDM/TPO/mod-bit) and are often priced separately from the shingled portion.
- Material choice. Basic shingle is cheapest; architectural, metal and premium systems cost more but last longer.
- Access & height. Steeper and taller homes need more setup, safety equipment and time.
- Extras. New flashing, attic ventilation, ice-&-water shield, eavestroughs and warranty coverage.
Asphalt vs. metal vs. flat — which is right for your home?
Asphalt shingle is the go-to for most Scarborough homes: affordable, good-looking and 20–30 years of life. Metal costs more up front but can last 40–70 years and sheds snow and ice well — strong long-term value on exposed roofs near the Bluffs and the lake. Flat systems (EPDM, TPO, modified bitumen) are for the low-slope additions so common on Scarborough homes. We'll walk you through the trade-offs for your home, budget and how long you plan to stay — more on low-slope roofs in our flat roof guide.
How to get an accurate Scarborough quote (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 (we are).
- Ask about both warranties — the manufacturer's on the materials and the workmanship warranty on the install.
