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.
