Roofing Cost in Ottawa (2026)
Quick Answer
Estimated rangeIn Ottawa, a roof repair typically costs about CAD 300-1,500, while a full asphalt-shingle roof replacement is often around CAD 6,000-15,000+ for a typical house, depending on size, pitch and tear-off requirements. Exact published Ottawa roofing price lists are uncommon, so most figures below are clearly marked estimates based on typical Canadian residential roofing market ranges, with official local sources used for tax and contractor-verification context.
Overview
Roofing costs in Ottawa vary widely because the city has a mix of older detached homes, semi-detached properties and newer suburban houses, all with different roof sizes, slopes and ventilation needs. The biggest price driver is usually whether you need a repair or a full replacement. Small repairs such as replacing missing shingles, sealing a flashing issue or patching a minor leak are usually much cheaper than stripping and re-roofing the whole surface. Material choice also matters: basic asphalt shingles are usually the lowest-cost mainstream option, while architectural shingles, metal roofing and complex valley or flashing work push costs higher. Ottawa’s climate is also relevant. Snow load, freeze-thaw cycles, ice damming risk and wind exposure can all increase the need for underlayment, ice-and-water shield, ventilation upgrades and careful flashing work. Disposal charges, access constraints and the number of storeys can add further cost. Consumers should also remember that Ontario HST applies to most residential roofing work. Before hiring, it is sensible to confirm that the contractor is a legitimate business and to check for local registration requirements and consumer-protection information. Because many roofing firms quote per project rather than per hour, the most useful way to budget is usually by common job type and roof size rather than labour rate alone.

Factors Affecting Price
- Roof size, slope and number of storeys
- Repair versus full tear-off and replacement
- Material type, such as basic asphalt shingles versus premium shingles or metal
- Flashing, valleys, skylights, chimneys and ventilation upgrades
- Season, weather access, disposal fees and urgency after storm damage
Local Context
In Ottawa, roofing quotes are usually given as project totals rather than retail-style price lists. Ontario HST of 13% typically applies. Tipping tradespeople is not standard. Winter weather, spring thaw damage and storm-related demand can all affect scheduling and pricing, and homes with steeper roofs or more complex layouts in older central neighbourhoods may cost more than simpler suburban roofs.
