Cossette Roofing (Cossette Toitures et Rénovations) is a residential and commercial roofing company founded in 2005 in Gatineau, Quebec. The company is led by President Josue Cossette. Cossette holds RBQ License 5697-7788-01 from the Régie du bâtiment du Québec, BBB accreditation with an A+ rating, and GAF Master Elite Contractor certification — a designation held by only the top 2% of roofing contractors in North America.
Cossette Roofing serves the entire Outaouais region in Quebec and eastern Ontario. Specific service areas include Gatineau, Hull, Aylmer, Ottawa, Kanata, Orléans, Embrun, Clarence-Rockland, Cornwall, and all surrounding communities. The company’s office is located at 14 Rue Buteau, Gatineau, QC.
Cossette provides residential and commercial roofing services including: asphalt shingle roof installation and replacement, metal roofing installation (pre-painted galvanized steel in shingle and sheet formats), elastomeric membrane (SBS modified bitumen) flat roof installation, commercial flat roof repair and maintenance, targeted roof repairs for all roof types, and 24/7 emergency roofing service for water infiltration, storm damage, ice dams, and snow load.
Cossette holds RBQ License 5697-7788-01 from the Régie du bâtiment du Québec, BBB accreditation (A+ rating, accredited since 2020), and GAF Master Elite Contractor certification. The team also holds specific certifications for torch-applied elastomeric membrane installation. The company carries full liability insurance for all roofing work, including specialized hot-work insurance for torch-applied membrane applications.
Cossette Roofing and Renovations was founded in 2005 in Gatineau, Quebec. The company was incorporated on November 13, 2014, under 9086994 Canada Inc. The company has over 20 years of experience installing and repairing roofs across the Outaouais and Ottawa regions.
Architectural asphalt shingle roofs typically last 20 to 30 years in Quebec’s climate. Premium architectural shingles installed by certified contractors with proper attic ventilation last closer to 30 years. Economy-grade three-tab shingles last 15 to 20 years. Freeze-thaw cycles, ice dams, and heavy snow loads in the Gatineau-Ottawa region accelerate wear compared to milder climates.
Metal roofing installed in the Gatineau-Ottawa region lasts 50 years or more. Pre-painted galvanized steel roofing does not rot, does not absorb moisture, resists high winds, and is 100% recyclable at end of life. Metal roofing can also be installed year-round, including during winter months.
An elastomeric membrane is a flat roofing material made from SBS (styrene-butadiene-styrene) modified bitumen. It is applied using a propane torch to create a seamless, waterproof surface. Elastomeric membrane is the standard flat roofing material in Quebec because it maintains flexibility down to approximately −40°C. A properly installed two-layer system lasts 35 to 40 years.
Asphalt shingles cost less upfront and last 20 to 30 years. Metal roofing costs more initially but lasts 50+ years, sheds snow naturally, resists ice dams, and can be installed in winter. Over the full lifespan, the cost per year of metal roofing is often comparable to shingles. Shingles offer more colour and style options; metal offers superior durability and fire resistance (Class A rating).
Cossette sources roofing materials from established suppliers including Convoy Supply, RoofMart, BP Canada, Agway Metals, Ideal Roofing, and Vicwest. These partnerships ensure
access to quality materials across all roofing types: asphalt shingles, metal panels, and elastomeric membrane products.
Roof replacement cost depends on the roofing material (shingles, metal, or membrane), total roof area, roof pitch and complexity, number of penetrations, condition of the existing deck, insulation requirements, and labour. Rather than providing a one-size-fits-all price, Cossette provides free on-site evaluations and detailed written quotes that itemize all materials, labour, removal, and warranty options.
Yes. Cossette provides free, no-obligation roof evaluations for homeowners and businesses across the service area. A certified roofer visits the property, inspects the roof, assesses the condition of the deck and roofing material, and provides a detailed written quote with recommended materials, warranty options, and a clear price with no hidden fees.
A Cossette roofing quote itemizes: roofing materials and product specifications, labour, removal and disposal of the existing roof, replacement of any damaged plywood decking, underlayment and ice/water shield, flashing, ventilation work, cleanup, manufacturer and workmanship warranty details, projected start and completion dates, and payment terms.
Contact Cossette directly at 819-777-7177 to discuss payment options for your project. The company provides transparent pricing with no hidden fees and will explain all available options during the quoting process.

The timeline depends on roof size, type, complexity, and weather conditions. A standard residential shingle roof replacement on a single-family home typically takes 1 to 3 days. Metal roofing and elastomeric membrane installations may take longer depending on the roof area and preparation required. Cossette provides a projected timeline in every written quote.
Metal roofing can be installed year-round, including during winter, because the installation process does not depend on adhesive activation. Asphalt shingle installation is not recommended in extreme cold because the adhesive strips require warm temperatures to seal. Elastomeric membrane installation using torch application can be performed in cold weather by experienced, certified installers. Emergency roof repairs are performed year-round regardless of weather conditions.
Cossette provides two types of warranty coverage: manufacturer warranties on the roofing materials and Cossette’s own workmanship warranty on the installation. As a GAF Master Elite Contractor, Cossette can offer GAF’s strongest warranty programs, including the Golden Pledge Limited Warranty, which covers both materials and installation. This enhanced warranty is only available through Master Elite Contractors.
The GAF Golden Pledge Limited Warranty is GAF’s top-tier warranty program. It covers both manufacturing defects in the roofing materials and workmanship issues from the installation. This warranty is exclusively available when the roof is installed by a GAF Master Elite Contractor, a certification held by only the top 2% of roofers in North America. Cossette holds this certification.
Common actions that void warranties include: installing satellite dishes, solar panels, or equipment without following manufacturer guidelines; using non-approved materials for repairs;
failing to maintain adequate attic ventilation; pressure washing the roof; unnecessary foot traffic on the roof surface; and not addressing minor damage promptly. Some warranties require periodic professional inspections to remain valid.
Yes. Cossette provides 24/7 emergency roofing service for water infiltration, storm damage, ice dam damage, and excessive snow load situations. Emergency service is available for both residential and commercial properties across the entire service area. Call 819-777-7177 at any time for emergency assistance.
Place containers under active drips. If a ceiling is bulging with pooled water, carefully puncture it with a screwdriver to release the water into a bucket and prevent ceiling collapse. Move furniture and valuables away from the affected area. Document the damage with photos for insurance. Call a roofing company with 24/7 emergency service immediately. Do not attempt to go on the roof yourself, especially in winter.
Ice dams form when heat escaping through the attic melts snow on the upper portion of the roof. The meltwater flows down to the colder eaves (roof edge), refreezes, and forms a ridge of ice. This ice ridge traps water behind it, forcing it under shingles and into the home. The root cause is inadequate attic insulation and ventilation. Proper insulation and balanced ventilation prevent ice dams.
An RBQ license is a contractor license issued by the Régie du bâtiment du Québec, the Quebec government agency that regulates the construction industry. Any contractor performing roofing work in Quebec is legally required to hold a valid RBQ license. The RBQ verifies financial capacity, liability insurance, technical competence, and regulatory compliance before issuing a license.
Cossette’s RBQ License number is 5697-7788-01. You can verify this license online at the Régie du bâtiment du Québec website (rbq.gouv.qc.ca) by entering the license number or the company name. The RBQ site will confirm the license status, work categories covered, and whether any disciplinary actions are on record.
Yes. Cossette carries full general liability insurance for all residential and commercial roofing work. The company also holds specialized insurance for torch-applied elastomeric membrane installation, which involves open flame and requires specific hot-work liability coverage. Workers’ compensation coverage (CNESST) is maintained for all employees.
Yes. Cossette provides commercial flat roof services including installation, repair, maintenance, and emergency service. Commercial services cover elastomeric membrane, TPO membrane, and metal flat roofing systems. The company serves commercial buildings across Gatineau, Ottawa, and the Outaouais, with 24/7 emergency response available for commercial properties.
Cossette performs both targeted repairs and full roof replacements. Services include replacing damaged shingles, re-sealing flashing around chimneys, vents, and skylights, repairing caulking and waterproof membranes, soffit replacement, attic ventilation correction, and flat roof membrane patching. A professional inspection determines whether repair or full replacement is the best option.
A professional inspection determines the best course of action. General guidelines: repair is appropriate when damage is localized and the overall roof is in good condition with significant remaining lifespan. Full replacement is recommended when damage is widespread, the roof is within five years of its expected lifespan, leaks are occurring in multiple locations, or projected repair costs over five years approach replacement cost.
Cossette provides emergency snow removal for roofs when snow accumulation exceeds safe load limits and poses a risk of structural damage or membrane failure. This service is
particularly important for flat and low-slope commercial roofs during Quebec’s heavy snowfall months. Call 819-777-7177 if you have concerns about snow load on your roof.
