The Case for Metal Roofing in Ottawa and Gatineau
The Ottawa-Gatineau area receives an average of 235 cm of snow per year — more than Toronto, Montreal, or Vancouver. Add in freeze-thaw cycles, spring ice dam formation, and summer UV exposure, and it becomes clear why roofing durability matters more here than in milder climates.
Metal roofing was originally the dominant roofing material in rural Quebec and Ontario for exactly this reason: it sheds snow naturally, does not rot, does not granulate, and does not absorb water. Modern pre-painted galvanized steel roofing brings those same performance characteristics to residential homes in Gatineau, Hull, Aylmer, Kanata, Orléans, and Ottawa with improved aesthetics and colour options.
Metal Roofing vs. Asphalt Shingles: Key Differences
Lifespan: Metal roofing is permanent. Asphalt shingles last 25–50 years depending on quality.
Snow performance: Metal sheds snow naturally due to its smooth surface. Shingles accumulate snow, increasing ice dam risk.
Maintenance: Metal requires virtually no maintenance. Shingles require periodic inspection and may need spot repairs.
Upfront cost: Metal roofing has a higher initial cost than asphalt shingles — typically 2 to 3 times more per square foot installed.
Long-term value: Over a 50-year period, metal roofing typically costs less than replacing asphalt shingles twice.
Energy efficiency: Metal reflects solar radiation, reducing summer cooling costs.
Environment: Metal is 100% recyclable. Shingles contribute significantly to landfill waste.
Types of Metal Roofing Available in Gatineau and Ottawa
Cossette Roofing installs two primary metal roofing formats in the Outaouais and Ottawa regions: shingle-profile steel (stamped steel panels shaped to resemble traditional asphalt shingles or cedar shakes, popular for residential homes) and standing seam (continuous vertical panels with concealed fasteners — the most wind-resistant and watertight metal roofing format).
Metal Roofing and Ice Dams in the Outaouais
Ice dams form when heat escaping from the attic melts snow on the roof surface, which then refreezes at the eaves. Metal roofing significantly reduces ice dam risk because snow slides off the smooth surface before it accumulates enough to cause a problem. For homes that have experienced recurring ice dam damage, switching to metal roofing is often the most effective long-term solution — in combination with proper attic insulation and ventilation.
Can Metal Roofing Be Installed Year-Round in Gatineau?
Yes. Unlike asphalt shingles, metal roofing can be installed year-round without temperature restrictions. This makes metal roofing a practical option for winter emergency replacements in Gatineau, Ottawa, and the Outaouais.
Frequently Asked Questions
How long does metal roofing last in Quebec’s climate?
Metal roofing is considered a permanent roofing material. Pre-painted galvanized steel installed correctly in Quebec’s climate typically outlasts the building itself. Cossette provides workmanship warranties on all metal roofing installations.
Does metal roofing increase home resale value in Gatineau?
Yes. A metal roof is a strong selling point in the Gatineau-Ottawa real estate market because buyers understand that it eliminates the need to budget for a future roof replacement. Metal roofing can meaningfully improve the perceived value and marketability of a home.
Is metal roofing loud in rain or hail?
When installed over a solid roof deck with underlayment — as Cossette installs — metal roofing is not noticeably louder than asphalt shingles. The decking and insulation layer absorb the sound effectively.
