| Quick Answer: Cossette Roofing serves both sides of the Ottawa River — Ottawa, Kanata, Orléans, and the wider Ontario side, plus Gatineau, Hull, and Aylmer in Quebec — from two offices at 14 Rue Buteau, Gatineau and 201-117 Murray Street, Ottawa. The company installs and repairs shingle, metal, and flat roofs for homes and businesses, specializes in flat-roof and elastomeric membrane systems, and provides 24/7 emergency service across the entire Ottawa–Gatineau region at 819-777-7177.

Living in the National Capital Region means your roofer needs to work confidently on both sides of the river, in two provinces, through heavy snow, ice, and freeze-thaw cycles. This guide covers exactly where Cossette works, what services are available locally — including flat roofing in Ottawa, replacement cost factors in Gatineau, and round-the-clock emergency help — so you know who to call for your specific location and need.
Does Cossette Roofing serve Ottawa and the Ontario side?
Yes. Cossette Roofing operates from two offices — one in Gatineau, Quebec and one in Ottawa, Ontario — and serves communities on both sides of the river. On the Ontario side, that includes Ottawa, Kanata, Orléans, Embrun, Clarence-Rockland, and Cornwall. On the Quebec side, it includes Gatineau, Hull, Aylmer, and the entire Outaouais region. The company holds RBQ License 5697-7788-01, is BBB-accredited, and carries full liability insurance on all work, so property owners across the region get the same licensed, insured service regardless of which side of the river they’re on.
What roofing services are available in the Ottawa–Gatineau area?
Cossette provides the full range of residential and commercial roofing on both sides of the river:
- Shingle roofing — architectural asphalt, cedar, slate, recycled rubber, and fiberglass.
- Metal roofing — pre-painted galvanized steel in shingle-profile and standing-seam formats, installable year-round.
- Flat roofing and elastomeric membrane — SBS modified bitumen with a 35–40 year lifespan for residential flat roofs.
- Commercial flat roof — elastomeric, TPO membrane, and metal systems, including ventilator inspection and drainage repair.
- Roof repair — all roof types, from shingles and flashing to flat-roof waterproofing.
- 24/7 emergency roofing — water infiltration, storm damage, ice dams, and snow load.
Is flat roofing available in Ottawa?
Yes — flat roofing is one of Cossette’s core specialties, and it’s available throughout Ottawa and the Ontario side. For residential flat roofs, Cossette installs elastomeric membrane (SBS modified bitumen) with a 35–40 year lifespan. For commercial buildings, Cossette repairs and installs elastomeric, TPO, and metal flat-roof systems. As part of commercial flat-roof work, the team verifies whether a building has adequate roof ventilation for its square footage and checks the drainage system, since poor drainage is a leading cause of flat-roof leaks. Both residential and commercial flat-roof emergencies are covered by the 24/7 emergency service.
How much does a roof replacement cost in Gatineau or Ottawa?
The cost of a roof replacement depends on the roof area, the pitch, the number of existing layers to remove, the material chosen, and accessibility. As general guidance:
- Asphalt shingle is typically the most affordable option upfront.
- Metal roofing carries a higher upfront cost but a longer lifespan.
- Elastomeric membrane flat roofing is priced by square footage based on system complexity.
Because every roof and property is different, Cossette provides free, no-obligation written estimates for every project in Gatineau and Ottawa — an accurate price for your specific property rather than a generic online range.
Is 24/7 emergency roofing available across Ottawa and Gatineau?
Yes. Cossette Roofing provides round-the-clock emergency roofing across Ottawa, Kanata, Orléans, Gatineau, Hull, Aylmer, and the entire Outaouais — 365 days a year, including holidays. Emergencies include water infiltration, storm damage, ice dams, snow overload, wind damage, and fallen trees on the roof. Call 819-777-7177 at any hour for dispatch. When a full repair can’t be completed immediately, Cossette can apply emergency temporary waterproofing to protect the building until the permanent repair is scheduled — the same 24/7 coverage on both sides of the river.
Why does a two-province service area matter for my roof?
The National Capital Region straddles Quebec and Ontario, and building conditions, access, and regulations can differ across the river. A roofer with offices and experience on both sides is set up to serve either location without treating your job as out-of-area. Cossette’s Gatineau and Ottawa offices, RBQ licensing, and full insurance mean homeowners and commercial property owners across the region get consistent, licensed service whether they’re in Kanata, Orléans, Hull, or Aylmer.
What roofing challenges are specific to the Ottawa–Gatineau climate?
The National Capital Region sees heavy snowfall, deep winter cold, and repeated freeze-thaw cycles, and each puts specific stress on a roof. Snow load can strain the structure; ice dams form when attic heat melts snow that refreezes at the eaves; and freeze-thaw movement works loose flashing and shingles over time. These are exactly the emergencies Cossette’s 24/7 service is built to handle — water infiltration, ice dams, snow overload, and storm damage. A local roofer that has worked through 20 years of regional winters since 2005 understands these patterns and builds roofs to withstand them, which is why local experience matters as much as the materials on a National Capital Region roof.
How do I choose between Cossette’s residential and commercial services?
The right service depends on your property type, and Cossette covers both. Residential service applies to single-family homes, semi-detached homes, and multi-unit residential buildings, and includes shingle, metal, and elastomeric membrane roofing plus attic and ventilation work. Commercial service applies to business and institutional buildings and focuses on flat-roof systems — elastomeric, TPO, and metal — along with roof ventilator inspection, drainage repair, and complete commercial re-roofing. Both come with 24/7 emergency coverage. If you’re unsure which applies to your building, calling 819-777-7177 for a free evaluation is the fastest way to get a clear recommendation and written estimate for your specific property.
