Choosing the right roofing contractor in Gatineau is not simply about finding the lowest price. Your roof is the primary weather barrier protecting your home from Quebec’s winters, spring thaws, summer storms, and fall windstorms. A poorly installed or under-spec’d roof can lead to water infiltration within years of installation, mould growth in the attic, structural damage to the deck and fascia, and repair costs that dwarf what you saved on the original installation. This complete guide gives Gatineau homeowners a practical, step-by-step framework for evaluating roofing contractors, understanding quotes, checking credentials, and making a decision you will not regret.
Step 1 — Verify the RBQ Licence Before Anything Else
The very first thing to confirm — before asking about price, availability, or any other detail — is the contractor’s RBQ licence. In Quebec, every contractor performing roofing work must hold a valid licence from the Régie du bâtiment du Québec. The licence number must appear on all estimates, contracts, and signage. A ten-digit number in the format XXXX-XXXX-XX is what you are looking for.
Do not take the contractor’s word for it — verify the number yourself in the official registry, which takes under two minutes. The registry confirms whether the licence is currently active, whether it covers the specific type of roofing work being done, and whether the contractor has any serious disciplinary issues on record. Working with an unlicensed contractor eliminates your legal recourse if the work fails and may void your home insurance coverage for damage related to the project.
Step 2 — Confirm Full Liability Insurance
A professional roofing contractor carries comprehensive liability insurance covering both property damage and worker injuries. Ask specifically for the certificate of insurance — a formal document from the insurer listing the coverage amounts and policy dates. Do not accept a verbal assurance or a business card with an insurance company name. The certificate should show general liability coverage and, if the contractor has employees, workers’ compensation coverage. If a contractor hesitates to provide this documentation, end the conversation.
Why does this matter? If a worker falls from your roof and the contractor does not have workers’ compensation, you could be held liable for the medical and legal costs. If falling tools or debris damage your neighbour’s property, liability insurance covers the claim. Without it, you may absorb the cost.
Step 3 — Look for Genuine Local Experience
The Gatineau-Ottawa region has a roofing climate unlike most of southern Canada. Average annual snowfall exceeds 200 centimetres. Freeze-thaw cycles can occur dozens of times per winter, placing repetitive stress on flashings, sealants, and membrane seams. Ice dams form along eaves when heat escapes from poorly ventilated attics, and when they melt, the water can travel back up under shingles or into wall cavities. Summer UV exposure degrades shingles and membrane surfaces over time.
A contractor with genuine local experience knows how to spec ice-and-water shield correctly, how to size attic ventilation to prevent ice dam formation, which shingle products hold up best in this specific climate, and how to address the drainage requirements of flat roofs in a region with heavy snow and freeze-thaw cycles. This knowledge only comes from years of working in the Outaouais — not from applying general roofing knowledge from a different province or region.
Cossette Roofing has operated exclusively in Gatineau, Ottawa, and the Outaouais since 2005. Every roofer on the team completes annual continuing education covering current roofing technology, code updates for both Quebec and Ontario, and manufacturer installation requirements.
Step 4 — Get Multiple Written Quotes
Never commit based on a single quote. Getting two or three written estimates from different licensed local contractors gives you a reliable sense of fair market pricing for your specific project. It also lets you compare the scope of work side by side — which often reveals important differences. One contractor might include full ice-and-water shield coverage; another might use a cheaper underlayment. One might include attic ventilation assessment; another might ignore it entirely. The lowest quote is not always the best value when you account for these differences.
A quality written quote should include the contractor’s name, address, and RBQ licence number; full scope of work detailing what is being removed and what is being installed; material specifications including brand, model, and colour; underlayment and ice-and-water shield details; disposal and cleanup of removed materials; a project timeline with start and completion dates; total price with no hidden fees; and the terms of both the manufacturer warranty and the workmanship warranty.
Step 5 — Check Reviews, References, and Accreditations
Online reviews on Google and the BBB provide real-world evidence of a contractor’s reliability, communication quality, and ability to handle problems when they arise. Look specifically for reviews that mention the contractor’s responsiveness after the job was done — a roofing company that stands behind its warranty is one that takes calls and returns to address issues rather than disappearing after the final payment.
For larger projects, ask the contractor directly for references from recent similar work in your area. A confident, established contractor will have no hesitation providing names. You can also cross-reference the contractor’s BBB standing, which shows their accreditation status and any formal complaints on record. Cossette Roofing has been BBB-accredited since 2020 and maintains an active review profile across multiple platforms.
Step 6 — Understand Manufacturer Certifications
For shingle roofing specifically, manufacturer certification programs provide a meaningful quality signal. GAF’s Factory-Certified Contractor program, for example, designates installers who meet GAF’s training, quality, and business standards. These certified contractors can offer customers enhanced system warranties — including GAF’s Golden Pledge warranty — that provide substantially better coverage than standard manufacturer warranties and are simply not available from non-certified installers. Cossette Roofing is a GAF Factory-Certified Contractor, which means eligible customers can access this enhanced warranty tier.
Before hiring, ask specifically: is your company certified by the manufacturer of the shingles you are recommending? If yes, what warranty tier does that certification qualify me for?
Step 7 — Clarify Every Aspect of the Warranty
Roofing warranties have two separate components that are often confused. The manufacturer warranty covers the roofing materials themselves against defects for a defined period — typically 25 years to lifetime for architectural shingles, depending on the product and the installation tier. The workmanship warranty, provided by the contractor, covers the installation itself — the labour, the flashing details, the sealing, and all the elements that are not covered by the manufacturer if the failure is due to how the product was installed rather than what it was made of. Both matter, and both should be provided in writing.
Ask specifically: how long is your workmanship warranty? What does it cover and what are the exclusions? What voids it? A reputable contractor will answer these questions clearly and put the answers in the contract.

Red Flags That Signal an Unreliable Contractor
Walk away from any contractor who cannot produce an RBQ licence number or proof of insurance — these are non-negotiable regardless of how attractive the price may seem. Door-to-door solicitation immediately after a storm is a tactic almost exclusively used by out-of-region operators who have no local business history and no intention of honouring a warranty. Insisting on full payment before work begins, providing only a verbal quote with no written breakdown, using high-pressure tactics like ‘this price is only valid today’, and having no traceable local address are all signs of an unreliable or unregistered operator.
Be especially cautious of quotes that are dramatically lower than others you have received. In roofing, an unusually low price almost always reflects a shortcut somewhere — inferior materials, missing underlayment layers, skipped ventilation work, or a contractor who plans to disappear after taking the deposit.

Frequently Asked Questions
How many quotes should I get for a roof replacement in Gatineau?
Two to three written quotes from licensed local contractors is the standard recommendation. It gives you a reliable reference point for fair market pricing and allows you to compare scope, materials, and warranty terms directly. Be cautious of quotes that are significantly lower than the others — they typically reflect shortcuts on materials or installation that will cost more to fix later.
How do I verify a roofing contractor’s RBQ licence in Quebec?
Visit the official RBQ website and use the licence holders’ registry. Enter the contractor’s 10-digit licence number and confirm it is currently active and covers roofing subcategories. This process takes under two minutes and is one of the most important steps you can take before hiring.
What is a GAF Factory-Certified Contractor?
GAF is one of North America’s largest shingle manufacturers. Their Factory-Certified Contractor designation is awarded to installers who meet GAF’s training standards and quality requirements. Certified contractors can offer customers enhanced system warranties, including the Golden Pledge warranty, that non-certified installers cannot access.
How long does a roof replacement take in Gatineau?
Most residential shingle roof replacements in Gatineau are completed in one to two days for a standard-sized single-family home. Larger or more complex roofs with multiple valleys, dormers, or steep pitches may take an additional day. Flat roof projects vary by size and system type.
