How much does a roof replacement cost in Hamilton?
A new roof in Hamilton costs $5,500 to $15,000 or more, according to a 2026 Hamilton price guide. Architectural shingles run $7,000 to $11,000 for a typical 1,500 to 2,000 square foot roof. Standing seam metal costs $14,000 to $25,000 or more for a roof of the same size.
| Job | Typical cost (CAD) | Source |
|---|---|---|
| Standard 3-tab shingles | $5,500 to $8,000 | Custom Contracting, 2026 |
| Architectural shingles | $7,000 to $11,000 | Custom Contracting, 2026 |
| Premium designer shingles | $10,000 to $15,000 | Custom Contracting, 2026 |
| Standing seam metal | $14,000 to $25,000+ | Custom Contracting, 2026 |
| Extra cost to remove 2 or 3 old layers | $1,500 to $3,000 | Custom Contracting, 2026 |
| Rotten deck sheet (4 x 8 ft) | $75 to $150 per sheet, plus labour | Custom Contracting, 2026 |
Old houses add cost. The same guide says many homes in central Hamilton and Westdale were built before 1960, and their roofs frequently hide two or three layers of shingles. Steep roofs cost more too: the guide adds 15% to 25% to labour for a pitch above 6/12.

How do you choose a roofing company in Hamilton?
Pick a Hamilton roofer by checking WSIB clearance, proof of insurance and at least three references, then get a written contract. Ontario does not license roofers, so these checks matter most. Check permits too: Hamilton needs one when you switch to a new roof material, but not to re-shingle.
- Check the licence. Ontario does not license roofing contractors, so the WSIB, insurance and contract checks below matter more. See the province’s advice on hiring a roofer in Ontario.
- Confirm WSIB clearance. Ask for the company’s WSIB account number and confirm a current clearance on WSIB’s free eClearance lookup.
- Ask for proof of liability insurance. A certificate of commercial general liability insurance should name the company that will do the work.
- Check the city licence. Hamilton says all contractors must hold a valid Trade and Contractor Licence, including roofers and other building repair, plumbing, drain and HVAC contractors. Search the City of Hamilton licensed contractors list.
- Get it in writing. Under Ontario law, any home renovation contract worth more than $50 must be in writing, and the final price cannot exceed an estimate by more than 10% unless you agree (Ontario consumer protection rules).
- Keep the deposit small. Ontario recommends a down payment of no more than 10%, and never paying in full before the work is done.
Ontario’s consumer guide gives a good reason to dig into references: “you often don’t see problems in roofing or paving for about a year or more after a project is done.” So ask each roofer for clients whose roofs went on at least a year ago. The province’s guide to hiring a roofer has more tips.
The City of Hamilton lists re-shingling with the same material as permit-free, but a roof in a new material needs a permit. We run the WSIB, insurance, reference and background checks before we match a roofer with you. If the attic needs work while the roof is open, compare attic insulation quotes in Hamilton too.

What do Hamilton homeowners ask about roof replacement?
Hamilton homeowners want to know what a new roof costs, how long it takes and when the city needs a permit. These answers use a 2026 Hamilton price guide, city permit rules and Ontario consumer advice. Each one stands alone, so read the one you need.
How much does a roof replacement cost in Hamilton?
A new roof in Hamilton costs $5,500 to $15,000 or more in 2026, based on a Hamilton price guide. Architectural shingles run $7,000 to $11,000 for a 1,500 to 2,000 square foot roof. Standing seam metal costs $14,000 to $25,000 or more, and each extra layer of old shingles adds to the tear-off bill.
Do I need a permit to replace my roof in Hamilton?
Not if you re-shingle with the same material. The City of Hamilton lists re-shingling a roof with the same roofing material among projects that need no building permit. Replacing roofing with a different material does need one, so a switch from shingles to metal needs a permit before work starts.
How do I check a roofer's WSIB coverage in Ontario?
Ask the roofer for its WSIB account number, then look up a clearance on WSIB's free eClearance site. Ontario says construction workers and independent operators must carry workplace safety and insurance coverage, with some exceptions. Check the clearance before work starts and again before you pay the final bill.
How long does a roof replacement take in Hamilton?
Most Hamilton roof replacements take 2 to 3 working days from tear-off to cleanup, according to a 2026 local price guide. Small bungalows can finish sooner and complex roofs take longer. Rain can stretch the job, so ask how the crew will cover an open roof overnight.
Is Pro House Maintenance free for Hamilton homeowners?

You compare their written quotes and choose who to hire. Our satisfaction guarantee backs work from the roofers we match.
