Your roof is your home’s first line of defence against the elements. When it reaches the end of its life, replacement is one of the largest home improvement investments you’ll make — but also one of the most critical. Here’s what a roof replacement costs in 2026, and what you need to know before getting quotes.
Roof Replacement Cost at a Glance
| Roofing Material | Cost per Sq Ft (Installed) | Typical Total (2,000 sq ft roof) |
| 3-Tab Asphalt Shingles | $3 – $5 | $6,000 – $10,000 |
| Architectural Asphalt Shingles | $4 – $7 | $8,000 – $14,000 |
| Metal Roofing (standing seam) | $10 – $20 | $20,000 – $40,000 |
| Wood Shake / Cedar Shingles | $8 – $16 | $16,000 – $32,000 |
| Slate Tile | $20 – $40 | $40,000 – $80,000 |
| Concrete / Clay Tile | $10 – $25 | $20,000 – $50,000 |
Most homeowners pay $8,000 to $16,000 for a roof replacement using architectural asphalt shingles — the most popular roofing material in the US — on a typical 2,000 sq ft roof.
What’s Included in a Roof Replacement?
A complete roof replacement involves far more than just new shingles. Here’s what a quality job includes:
- Removal and disposal of old roofing material ($1–$2/sq ft)
- Inspection and repair or replacement of damaged roof decking (plywood/OSB)
- Installation of ice and water shield membrane along eaves and valleys
- Synthetic roofing underlayment over the full deck
- New drip edge flashing along all edges
- New flashing around chimneys, skylights, vents, and pipe penetrations
- Installation of new shingles or chosen roofing material
- New ridge cap and ventilation components
- Full clean-up and magnet sweep for nails
What Drives the Cost Up?
Roof Pitch (Steepness)
Steep roofs are more dangerous and slow to work on. A steep pitch (above 8/12) adds 25–50% to labour costs compared to a low-slope roof.
Number of Layers to Remove
Most areas allow up to 2 layers of shingles before a full tear-off is required. Tearing off two layers instead of one adds $1–$2/sq ft to the job.
Roof Complexity
Hips, valleys, dormers, chimneys, and skylights all require custom flashing work and slow down installation. A simple gable roof costs significantly less per square foot than a complex hip-and-valley roof.
Decking Damage
If the plywood or OSB decking underneath is rotted or damaged, it must be replaced before new roofing goes down. Decking repairs cost $70–$100 per sheet of plywood — budget a contingency of $500–$2,000 for older roofs.
How Long Does Each Roofing Material Last?
| Material | Typical Lifespan | Key Advantage |
| 3-Tab Asphalt | 15 – 20 years | Lowest cost |
| Architectural Asphalt | 25 – 30 years | Best value for most homes |
| Metal (standing seam) | 40 – 70 years | Near-zero maintenance |
| Wood Shake | 20 – 30 years | Natural appearance |
| Slate | 75 – 150 years | Longest lifespan available |
| Clay / Concrete Tile | 40 – 50 years | Excellent in hot climates |
Insurance and Financing
If your roof was damaged by a storm, hail, or wind, your homeowner’s insurance may cover part or all of the replacement cost, minus your deductible. File a claim before getting contractor quotes — many roofing companies have dedicated insurance claim teams who can assist. Check your policy carefully: some older policies cover actual cash value (depreciated), not replacement cost.
Tips to Save Money
- Get quotes from at least 3 licensed, insured roofing contractors — never accept the first quote
- Choose architectural asphalt shingles — they offer the best balance of cost, performance, and longevity for most homes
- Avoid roof-over (adding new shingles on top of old) — it saves money now but shortens the life of the new roof and hides underlying problems
- Ask about manufacturer extended warranties — some premium shingle lines offer 50-year warranties when installed by certified contractors
- Schedule in late autumn or winter when roofers are less busy — you may negotiate 5–15% off
- Check for utility rebates if installing a cool roof or metal roofing with high solar reflectance
