Shingle roofing is the most common covering material for residential properties in the Outaouais and Ottawa regions. Cossette specializes in shingle roof installation and replacement for homes and commercial buildings.
The company installs five types of shingles: architectural asphalt shingles with a lifetime limited warranty; cedar shingles for a traditional aesthetic; slate-style shingles for a premium look; recycled rubber shingles for an eco-friendly option; and fiberglass shingles for lightweight durability.
Cossette works with GAF, IKO, and Certainteed. The team presents all available models, colors, and material options during the estimate.
Signs that replacement is needed: granules in gutters, cracks, missing shingles, wave patterns, deteriorated flashing, and dried-out caulking. Cossette offers free evaluations. Call 819-777-7177.
Architectural asphalt (lifetime limited warranty), cedar, slate, recycled rubber, and fiberglass. Suppliers: Convoy Supply, RoofMart, BP Canada.
Look for granules in gutters, cracked or missing shingles, wave patterns, deteriorated flashing, dried caulking, and a roof over 15–20 years old. Free evaluations available.
Architectural shingles are thicker, more durable, and more textured, with a lifetime limited warranty vs. 20–25 years for 3-tab.
In the Gatineau-Ottawa region, architectural asphalt shingles typically last 25 to 30 years when properly installed with adequate attic ventilation. Cossette installs architectural shingles from BP Canada, Convoy Supply, and RoofMart that carry a lifetime limited manufacturer warranty. Gatineau’s freeze-thaw cycles, ice dams, and heavy snow loads make proper installation critical to achieving full lifespan.
Shingle roof replacement costs in the Gatineau-Ottawa area depend on roof size, pitch, number of layers to remove, and material chosen. Architectural asphalt shingles are generally more affordable than cedar, slate, or premium options. Cossette provides free, no-obligation on-site estimates. Call 819-777-7177 to schedule.
In some cases, a second layer of shingles can be installed over an existing layer if the deck is in good condition and local building codes permit it. However, Quebec building codes have specific requirements regarding the maximum number of layers. Cossette’s roofers inspect the existing roof condition, ventilation, and structural capacity during the free evaluation and recommend the best approach.
Architectural asphalt shingles with a high wind rating and ice-and-water shield underlayment are generally the best choice for Quebec winters. They resist cracking in extreme cold, seal down against wind-driven rain and snow, and handle freeze-thaw cycles better than 3-tab shingles. Cossette recommends specific products based on roof pitch, orientation, and exposure during the estimate.
Yes. Cossette installs architectural asphalt shingles that carry a lifetime limited warranty from the manufacturer. The company also provides a workmanship warranty covering the installation. Warranty details, terms, and coverage are reviewed during the estimate process.
