A typical 2,000 sq ft asphalt-shingle roof replacement in the GTA costs $8,500–$14,000 in 2026. Premium architectural shingles run $11,000–$16,500. Standing-seam metal: $18,000–$32,000. Cedar shake: $24,000–$45,000. Synthetic slate: $28,000–$50,000+. Final price depends on home size, slope complexity, decking condition, tear-off depth, and access. AUK Roofers gives you a written, line-item, fixed-price quote within 24 hours of a free drone inspection.
What drives the actual price
Material is one variable. The other six matter just as much, and most homeowners only learn about them after signing. Here's the full list:
Roof square footage (each 'square' = 100 sq ft of roof surface, not floor surface)
Slope complexity — number of valleys, dormers, hips, and skylights
Tear-off depth — single layer vs two or three layers (older homes)
Decking condition — rotten plywood adds $4–$7 per sq ft replaced
Access — three-storey homes, tight side yards, no driveway add staging cost
Underlayment grade — synthetic vs felt, ice-and-water shield coverage area
Ventilation upgrades — ridge vents, soffit baffles, attic fan replacement
Asphalt shingle replacement — $8,500 to $16,500
Asphalt is the most common GTA roof material because it's the cost/lifetime sweet spot — 25–30 years of life on architectural shingles, fully recyclable, and replacement is 1–3 days. Pricing breaks down roughly:
3-tab asphalt (entry-level, 12–18 yr life): $7,500–$10,500 — we generally don't recommend this anymore
Architectural asphalt (mid-grade, 25–30 yr life): $9,500–$13,500
Add $1,500–$3,500 for full plywood deck replacement on older homes
Add $800–$1,500 for premium ice-and-water shield coverage
Metal roofing — $18,000 to $32,000+
Standing-seam metal is the longest-lifetime option short of slate, with 40–70 year service life. It's heavier on upfront cost but lighter on lifetime cost than two cycles of asphalt.
Standing-seam steel (most common): $18,000–$26,000 on a 2,000 sq ft home
Ribbed / agricultural panel (less common in residential GTA): $14,000–$20,000
Underlayment, ventilation, snow guards typically add $2,000–$4,000
Cedar, slate, and synthetic — $24,000 to $50,000+
Premium materials are typically reserved for heritage homes, luxury estates, or homeowners specifically targeting 50–100 year service life. They require contractors who know the system — installation mistakes are expensive to fix.
Cedar shake: $24,000–$45,000, 30–50 year life, requires periodic treatment
Natural slate: $40,000–$80,000+, 75–100+ year life, structural assessment required
Synthetic slate / composite: $28,000–$50,000, 50+ year life, lighter than natural
Synthetic cedar: $22,000–$38,000, 50+ year life, fire-resistant
What's included in an honest GTA quote
Every AUK Roofers replacement quote is line-item — you see exactly what each component costs, never a single lump sum. A complete quote should always include:
Tear-off and disposal of existing roof (specify how many layers)
Decking inspection and replacement allowance per sheet
Ice-and-water shield coverage area (in sq ft) along eaves and valleys
Underlayment specification (synthetic, weight)
Shingle / panel material, brand, model, colour, and warranty length
Flashings — drip edge, valley, step, chimney, vent
Ventilation — ridge vent, soffit, attic fan
Workmanship guarantee in writing — minimum 10 years, ideally 25
Cleanup, magnet sweep, and disposal removal
WSIB and liability certificate numbers on the quote
Financing and timing
Most GTA homeowners structure replacement as a 36–60 month financing plan rather than draining savings or HELOC equity. Approval is typically within 24 hours through our financing partner, and rates are competitive with home-improvement loans. We'll lay out the math without pressure during the quote.
Common questions.
Direct answers, no filler.
How much for just a small repair instead of full replacement?
Repairs start at $299 for minor flashing, vent boot, or shingle work. Most repairs run $299–$1,200. We'll always tell you honestly when repair is the right call vs replacement — sometimes a $400 fix buys you 5 more years.
Why do quotes from different roofers vary so much?
Three reasons: scope (some skip ice-and-water shield, ventilation, or drip edge), materials (different shingle grades, different warranty lengths), and crew quality. A $7,500 asphalt quote on a 2,000 sq ft home in 2026 is almost always cutting one of the three.
Does a new roof add value to my home?
Yes — typical GTA recovery is 60–75% of replacement cost on resale. More importantly, an aging roof is the #1 reason home inspections flag major repairs and kill deals. If you're selling within 3 years and your roof is past 20, replacement is usually the right call.
How long does a roof replacement actually take?
Asphalt: 1–3 days. Metal standing-seam: 4–7 days. Cedar / slate / synthetic premium: 7–14 days. We give you a firm schedule before we start and we hit it.
Do I need to be home during the replacement?
Not required. We need access to a power outlet, a place to stage materials, and a contactable phone. We protect landscaping with tarps and finish each day with a magnet sweep for nails.
Is the price fixed or can it change mid-job?
Fixed unless we find rotten decking under tear-off. Decking replacement is quoted per sheet upfront ($90–$140 per 4×8 sheet typical) so there are no surprises — just an honest add-on if we find rot.
What's the warranty on a GTA roof replacement?
Manufacturer warranty on materials: 25 years to lifetime depending on system. Workmanship warranty on labour: 25 years from AUK Roofers, transferable to next owner. Both in writing on the quote.
Can I just patch instead of replacing?
Sometimes. If your roof is under 18 years and damage is localized, a quality repair often makes sense. Past 22 years, repairs become diminishing returns — you're putting good money on a system about to fail elsewhere. We'll tell you honestly which side of the line you're on.
