How much does a Roofer cost in Gatineau in 2026?

What's Involved

A roofing project typically involves stripping the old shingles or membrane down to the decking, inspecting and repairing any damaged sheathing, installing ice and water shield in vulnerable areas, laying new underlayment, and applying the final roofing material. Flashing around chimneys, vents, and valleys is replaced or sealed, and ridge vents or other ventilation components are installed.

For Canadian homes, proper roof ventilation and ice-and-water membrane installation are critical. Building codes require ice protection along eaves in all provinces, and in Gatineau where freeze-thaw cycles are common, this prevents costly ice dam damage. Most residential roofs use asphalt shingles, though metal roofing and flat-roof membranes (TPO, EPDM) are also common.

Roof replacements are weather-dependent. Reputable contractors in Gatineau schedule work during dry periods and can typically complete a standard residential roof in 1-3 days.

Factors That Affect Cost

• Roof size — Measured in "squares" (100 sq ft each); a typical home is 20-35 squares.
• Material choice — Architectural asphalt shingles ($4-$7/sq ft) vs. metal ($8-$14/sq ft) vs. cedar shake ($10-$18/sq ft).
• Number of layers to remove — Removing multiple old layers adds disposal time and cost.
• Roof pitch and complexity — Steep or multi-gabled roofs require more safety equipment and labour.
• Decking repairs — Rotted sheathing replacement adds $50-$100 per sheet of plywood.
• Ventilation upgrades — Adding ridge vents, soffit vents, or attic baffles costs $300-$1,500.
• Permits — Most municipalities in Gatineau require a permit for re-roofing, adding $100-$500.

How to Save Money

1. Get quotes during the off-season (late fall or early spring) when roofing companies in Gatineau may offer lower pricing.
2. Choose standard architectural shingles with a 30-year warranty — they offer the best value for most Canadian homes.
3. Collect at least three detailed quotes and compare warranties, material specs, and cleanup terms.
4. Ask about manufacturer rebates or contractor promotions on premium shingle lines.
5. Address minor repairs promptly — a $300 flashing repair prevents a $15,000 re-roof from water damage.

Hiring Tips

1. Verify the contractor is licensed (RBQ in Quebec) and carries liability insurance plus workers' compensation.
2. Ask for their WSIB/WCB clearance certificate — roofing has high workplace injury rates.
3. Get a written quote that details material brand and product line, warranty terms, and disposal method.
4. Request references and check completed roofs in Gatineau that are at least 2-3 years old to assess durability.
5. Confirm they install ice and water shield per code and provide manufacturer warranty registration.
