For a typical 1,500 to 2,000 sq ft home, an asphalt shingle replacement in Ottawa currently averages between $7,200 and $14,500, depending on the shingle grade and roof complexity.

Yes. Due to Ottawa's average annual snowfall of 223 cm, local building standards often require enhanced ice and water shields and specific ventilation upgrades, which can add $500 to $1,500 to the total project cost.

Metal roofing is significantly more expensive upfront, averaging $22,500 in Ottawa for 2026. Premium standing seam systems for larger luxury homes can exceed $55,000.

Permits are generally not required for 'like-for-like' shingle replacements. However, if structural repairs to the trusses or changes to the roofline are needed, a City of Ottawa permit is required, typically costing between $100 and $300.
