How Much Does a New Roof Cost in Canada?

A useful roof replacement budget starts with a measured roof and a defined scope. Ask contractors to price the same work before comparing totals. A price for replacing the covering alone is not directly comparable with one that also includes removal, decking repairs and changes to other roof components.

A Toronto price example, with clear limits

Home Vision Contracting’s Toronto roofing FAQ publishes a new-roof range of $6,000–$15,000 or more and says its clients invest $8–$12 per square foot for a full replacement. These are the contractor’s own published figures, checked October 14, 2026. They are not an Experts.ca survey or a national average.

The answer does not provide a dated project sample or specify tax treatment and all inclusions. Treat the figures as one local reference, not an estimate for your home or an endorsement of the provider. Ask for a current written quote with its measurement basis, scope and taxes. Do not combine the project total and per-square-foot figures as if they described a single example roof.

Check what area is being priced

IKO’s homeowner FAQ defines a roofing square as 100 square feet of roof surface. Ask whether your estimate uses square feet, roofing squares or a fixed project price, and request the measured area behind it.

Do not substitute the home’s advertised interior floor area for the roof measurement. Ask the estimator to identify the roof sections included, explain how the area was measured and separate any material allowance for cuts and waste. If two quotes use different areas, resolve that difference before comparing their unit prices.

Use the same scope for every quote

The following questions are a worksheet for your project. They do not mean that every roof needs every item.

• Existing roof and removal: Which sections are included? Will existing coverings be removed, and does the estimate include disposal and protection of the property during removal?
• Replacement system: What material, manufacturer and product are proposed? Ask for the specified underlayment, edge details and other components to be listed, with optional alternatives priced separately.
• Flashing and penetrations: What work is included around chimneys, skylights, vents and roof intersections? Ask which existing components will be kept and why.
• Decking and hidden conditions: What can be assessed before removal? For damage discovered later, request a written approval process and a clear basis for extra charges, such as an agreed unit price.
• Access and protection: What arrangements are included for access, equipment, waste collection, landscaping protection and cleanup? Ask whether those costs are already in the total.
• Ventilation and related work: Does the proposal include any changes to ventilation, insulation, gutters or structural elements? Ask for the reason and price for each proposed addition.
• Final total: Which allowances, exclusions, taxes and possible extra charges remain? Identify which amounts are fixed and which depend on measurements or conditions not yet confirmed.

Compare complete estimates, not headline prices

The federal home-renovation guidance recommends meeting at least three potential contractors, giving them comparable specifications and obtaining estimates that include labour, extra charges and taxes. It also recommends checking references and insurance. Use those checks alongside the roofing scope above.

Place each quote beside the same checklist and mark included, excluded or unclear for every item. Ask about missing items before deciding which total is lower. Keep optional upgrades separate from essential work so that the comparison does not depend on silently changing the project.

Confirm repair options and local approvals

Ask the contractor to document the condition found, explain the proposed work and say whether a repair option is available. Request photographs or a written assessment you can review from the ground. Age alone is not a diagnosis, and this guide does not establish a replacement deadline or a guaranteed lifespan for your roof.

Check the proposed scope with your municipal building authority and put responsibility for permits in the contract, as the federal guidance recommends. Do not assume a rule about replacing a covering also applies to structural changes. This guide does not claim that a particular number of existing roofing layers is permitted across Canada.

Read product and workmanship warranties separately

IKO’s warranty FAQ says its asphalt-shingle limited warranty covers manufacturing defects that result in leaks, subject to the applicable terms, and does not cover incorrect application. That is a manufacturer-specific example of why a product warranty should not be treated as the installer’s promise about workmanship.

For the proposed products and contractor, request the actual written warranties. Ask who handles a claim, what labour and removal costs are covered, what exclusions apply and whether coverage changes over time or on sale of the home. Keep those documents with the signed scope and invoice; a long warranty label alone does not answer those questions.

Before authorizing the work

Resolve exclusions and approval procedures in writing. Ask for the planned start, weather contingency, cleanup and handover arrangements, and a payment schedule tied to the agreed contract. Keep your comparison sheet so that any later change can be checked against what you approved.
