Yes, a permit is mandatory for flat or low-sloped roofs. For sloped roofs, a permit is only required if the building is in a historical district. Fees are $9.80 per $1,000 of work value, with a minimum of $167.40 for residential buildings.
Montreal bylaws generally require 'cool roofs' for flat surfaces. This means using white or highly reflective materials (like white TPO, EPDM, or white gravel) with a Solar Reflectance Index (SRI) of at least 66 to combat the urban heat island effect.
For a standard 1,000 sq. ft. duplex with a flat roof, costs in 2026 typically range from $13,000 to $18,000 for TPO/EPDM membranes, or up to $23,000 for a high-durability elastomeric membrane.
Residential construction costs in Montreal saw a significant 8.4% year-over-year increase as of Q2 2026, driven primarily by skilled labor shortages and a 6-10% rise in material costs from major manufacturers like GAF and CertainTeed.
