Choosing the right metal roofing contractor is as important as choosing the material itself. Indeed, a poorly executed installation can compromise the durability of your roof, void your warranties and lead to unexpected costs. Yet not all roofers have the expertise needed to work with metal.
In this article, we detail the essential criteria to check before signing a contract. RBQ licence, warranties, specific experience and quotes: you’ll know exactly what to look for to entrust your project to the right professional.
The RBQ licence: the first non-negotiable criterion
In Quebec, every construction contractor must hold a valid licence from the Régie du bâtiment du Québec. This is the absolute baseline. Without this licence, a roofer is operating illegally and you lose all protection if something goes wrong.
For roofing work, the contractor must hold subclass 7.0 (insulation, waterproofing, roofing and exterior cladding). You can check the validity of this licence in seconds in the RBQ’s online registry. Also, make sure that the name on the quote exactly matches the one listed in the registry.
In addition, obtaining this licence requires a $20,000 licence security (surety bond). This amount protects consumers in the event of work that is not completed or poorly executed. As a result, a metal roofing contractor who holds a licence already demonstrates a minimum level of seriousness. Also check whether complaints have been filed against them with the RBQ before going any further.
Specific experience with metal: a must
Installing a metal roof differs considerably from installing asphalt shingles. Fastening techniques, flashing details and managing thermal expansion require specific know-how. An excellent shingle roofer is therefore not automatically competent with metal.
Ask the contractor how many metal roofs they’ve installed in recent years. Also ask for photos of completed projects and client references. A serious professional won’t hesitate to provide this information.
Also check whether the roofer is accredited by the manufacturer of the materials they use. This accreditation confirms that they have received specific training and follow the recommended installation methods. By choosing a certified installer, you also protect the validity of your manufacturer’s warranty.
The warranties offered: read before you sign
A good metal roofing contractor offers clear, detailed warranties in writing. It’s essential to clearly distinguish between the two types of protection.
- Labour warranty: it covers installation errors such as leaks, poorly installed flashing or inadequate fasteners. Its duration generally ranges from 5 to 10 years, depending on the contractor.
- Manufacturer’s warranty on materials: it covers product defects such as premature corrosion or peeling paint. For the SSAB steel used by Metal Roof Canada, this warranty reaches 50 years and is non-prorated.
Make sure both warranties are spelled out in black and white in your contract. Also ask whether the manufacturer’s warranty is transferable if you sell your property. This detail adds concrete value to your home on the real estate market.
The detailed quote: your best protection
A vague quote is a red flag. A professional roofer must provide a precise document that describes every aspect of the work.
Your quote should include the following:
- Materials: type of metal, gauge, profile, colour and manufacturer.
- Labour: estimated number of days and crew composition.
- Preparatory work: removal of the old roof covering, inspection of the roof frame and replacement of damaged wood if necessary.
- Insulation and ventilation: adding or improving existing insulation and checking attic ventilation.
- Warranties: duration and conditions of the labour warranty, as well as the manufacturer’s warranty certificate.
- Schedule and payment terms: start and end dates of the work, deposit amount and payment schedule.
By comparing at least three detailed quotes, you’ll be able to evaluate each offer fairly. However, beware of abnormally low prices. They often hide lower-quality materials or unmentioned extras.
Red flags to watch for
Certain behaviours should prompt you to walk away. Indeed, an unreliable metal roofing contractor can often be recognized by these signs.
First, a contractor who refuses to show their RBQ licence doesn’t deserve your trust. Likewise, one who demands full payment before the work begins represents a significant risk. A reasonable deposit is between 10% and 15% of the total amount.
Furthermore, be wary of roofers who don’t go up on your roof before writing their quote. A serious assessment requires a visual inspection of the slope, surface area and condition of the roof frame. Finally, a contractor who offers no written labour warranty should be ruled out without hesitation.
Why local experience matters
Quebec’s climate imposes constraints that only a roofer with local experience fully understands. Freeze-thaw cycles, snow buildup and high winds require adapted installation techniques. A roofer who knows these realities will know how to install snow guards in the right places and adjust the fasteners accordingly.
In addition, a contractor established in your area will be easier to reach if you need them after the work. Proximity also makes follow-up inspections and quick interventions easier. Metal Roof Canada, in business since 2012, serves the Montreal, Quebec City, Ottawa and Toronto areas, among others, with recognized expertise in standing seam roofs adapted to the Canadian climate.
Conclusion
Choosing the right metal roofing contractor requires diligence. Check the RBQ licence, demand written warranties and favour a metal specialist. Compare at least three detailed quotes before making your decision. These checks will save you from many unpleasant surprises.
