Ottawa FAQ
How much does a new roof cost in Ottawa in 2026?
A full architectural-shingle re-roof on a typical Ottawa detached home costs $8,500 to $22,000 before HST in 2026, or $7.50–$11.00 per sq ft installed. Ottawa pricing runs slightly under Toronto for shingles but on par for metal due to higher snow-load engineering.
How do I verify an Ottawa roofer is legitimate?
Verify an Ottawa roofer in four steps: (1) WSIB clearance certificate (mandatory), (2) $2M minimum civil liability insurance, (3) City of Ottawa building permit for any structural change, (4) written contract with brand, grade, ice & water shield extent and a deposit of no more than 10%.
Does Ottawa snow load require a different roof spec?
Yes. Ottawa is in Ontario Building Code climate zone with a ground snow load of 2.5 kPa, higher than Toronto's 1.7 kPa. Trusses, fasteners and snow-guard placement must reflect this. Confirm the contractor specifies the snow-load assumption in writing for any structural work.
When should an Ottawa roof be inspected after winter?
Inspect an Ottawa roof in mid-April once the freeze-thaw cycle ends. Check for lifted shingles at the eaves (ice-damming), nail-pop on south-facing slopes, granule loss in gutters, and any soffit-vent blockage from re-frozen meltwater. Document with photos before requesting a quote.
