How to Find and Vet the Best Roofing Contractors in Montreal, QC

In Quebec, roofing contractors must hold a valid license from Ordre des métiers du bâtiment et du bois du Québec (OMMQ) or operate under a licensed general contractor. Before hiring, verify their license status on the OMMQ registry at www.ommq.qc.ca—this is your first and most important vetting step. A contractor operating without proper licensing can leave you liable for injuries, void insurance claims, and result in substandard work that won't pass final inspection. Ask your contractor directly for their license number and confirm it matches their business name. Never accept verbal confirmation or promises to "get licensed after the project." Licensed contractors understand Montreal's building department requirements and stay current with Quebec's roofing codes, which specify minimum slopes, materials, and ventilation for our climate.

Your roofing contractor must carry workers' compensation insurance (couverture CNESST) and general liability insurance of at least CA$2 million. Request certificates of insurance directly from their provider—not from the contractor—and confirm they're current. Quebec law holds homeowners partially liable if a worker is injured on your property and the contractor lacks proper coverage. For Montreal's unpredictable weather and high-altitude work, liability claims are common. Ask your contractor how they handle weather delays and whether their insurance covers equipment damage. Verify that their policy covers the specific scope of your project (new installation vs. repair) and that your property is named as an additional insured. A reputable contractor will provide this documentation without hesitation; reluctance is a major red flag.

Always obtain at least three quotes from different contractors before deciding. Roofing costs in Montreal typically range from CA$8,000 to CA$25,000+ depending on roof size, pitch, material (asphalt shingles, metal, or slate), and removal of old roofing. A quote significantly lower than competitors often indicates corner-cutting or hidden costs that appear later. Detailed quotes should break down labor, materials, permits, disposal, and warranty separately. Ask whether the quote includes a site visit to assess your roof's condition, structural issues, or ventilation needs—estimates without inspection are unreliable. Pay attention to how contractors handle your insurance deductible: some will absorb it into their pricing, others won't address it, and unethical contractors may try to inflate invoices to bypass it. A transparent contractor explains how your deductible affects the final cost and won't encourage insurance fraud.

Avoid any contractor who pressures you to pay in full upfront or requests cash-only payment—legitimate businesses accept cheques and credit cards for accountability. Contractors who don't provide written contracts, quotes, or warranties are difficult to pursue legally if problems arise. Be wary of door-to-door roofers offering "emergency repairs" or claiming storm damage needs immediate action; many are transient and disappear after payment. Contractors who discourage getting multiple quotes or dismiss your insurance deductible as irrelevant are often working against your financial interests. If a contractor's quote includes language about avoiding insurance claims or inflating invoices, report them to the OMMQ immediately—this is insurance fraud. Finally, any contractor who dismisses Montreal's building codes or suggests shortcuts for cost savings doesn't meet Quebec's standards and will create problems during final inspection.

Requesting quotes from verified contractors eliminates much of the vetting burden. ProvenQuote's network includes only licensed, insured roofing contractors who meet Quebec's regulatory requirements. When you request quotes through ProvenQuote, contractors are required to disclose their license status, insurance coverage, and warranty terms upfront. You'll receive multiple quotes from contractors in Montreal, all transparent about deductibles and project timelines, so you can compare apples to apples. This saves time and protects you from unlicensed operators or contractors with poor insurance coverage.
