Why Roofing Material Choice Matters in the Gatineau Climate
Gatineau, Quebec experiences some of the most demanding weather conditions for roofing in Canada. Homeowners face heavy snowfall accumulations, freeze-thaw cycles that stress roofing membranes, spring ice dams, and summer heat that accelerates shingle granule loss. Choosing the wrong roofing material can mean premature failure, water infiltration, and costly repairs within a decade.
Cossette Roofing has been installing roofs in Gatineau since 2005. In that time, the team has completed more than 10,000 residential and commercial roofing projects across Gatineau, Hull, Aylmer, Ottawa, and the broader Outaouais region, giving them firsthand insight into how different materials perform locally.
Architectural Asphalt Shingles: The Most Popular Choice in Gatineau
Architectural asphalt shingles — also called dimensional or laminated shingles — are the most widely installed roofing material in Gatineau and the Ottawa Valley. They consist of a fibreglass mat coated with asphalt and embedded mineral granules, shaped into a layered, three-dimensional profile.
Lifespan: 25 to 50 years depending on product grade and attic ventilation.
Warranty: Lifetime limited manufacturer warranty available on premium products.
Cost: Most affordable roofing option per square foot — suitable for most budgets.
Performance: Rated for wind resistance up to 130 mph on premium products. Good performance in Quebec’s freeze-thaw cycles when properly installed over a quality ice-and-water membrane.
Cossette Roofing is a GAF Factory-Certified Contractor, which means the team is trained and tested in the proper installation of architectural shingle systems — a requirement for accessing enhanced Golden Pledge warranty coverage.
Metal Roofing: The Premium Long-Term Option
Pre-painted galvanized steel roofing — available in shingle profile and standing seam formats — is the longest-lasting roofing option available for Gatineau homes. Metal is particularly well-suited to Quebec’s climate because it sheds snow efficiently, resists ice dam formation, and does not absorb moisture.
Lifespan: Permanent — metal roofing typically outlasts the building it covers.
Maintenance: Minimal. Metal does not granulate, curl, or crack.
Energy efficiency: Reflects solar radiation, reducing summer cooling loads.
Recyclability: 100% recyclable at end of life.
Cossette installs metal roofing year-round in Gatineau, Hull, Aylmer, and Ottawa. The company carries both shingle-profile steel (for homes that prefer a traditional aesthetic) and standing seam systems (for contemporary or agricultural applications).
Cedar, Slate, and Recycled Rubber Shingles
Cossette Roofing also installs cedar shake shingles, natural slate, and recycled rubber shingles for homeowners seeking premium natural aesthetics or eco-conscious materials. Cedar and slate require additional structural consideration due to weight. Recycled rubber shingles offer excellent impact resistance and are a sustainable alternative that mimics the look of slate.
Elastomeric Membrane for Flat or Low-Slope Sections
Homes in Gatineau with flat roof sections — garages, rear additions, or walk-out basements — require an elastomeric membrane (SBS modified bitumen) system rather than shingles. Cossette installs residential flat roofing systems with a lifespan of 35 to 40 years.
Frequently Asked Questions
Can asphalt shingles be installed in winter in Gatineau?
Yes. Cossette Roofing installs shingle roofing year-round in Gatineau, including in winter. Cold-weather installation requires specific procedures — including the use of self-sealing strips that activate with summer heat — and the team is trained accordingly.
What roofing material is best for heavy snowfall areas?
Metal roofing is the best performer in heavy snow environments because its smooth surface allows snow to slide off naturally. Architectural shingles also perform well when the attic is properly ventilated and an ice-and-water membrane is installed at the eaves.
Does Cossette offer a warranty on shingle installations?
Yes. As a GAF Factory-Certified Contractor, Cossette offers manufacturer warranty coverage on GAF shingle systems, including enhanced warranty options. Workmanship warranties are also provided. Details are reviewed at the time of your free estimate.
