How to Find and Vet a Licensed Roofing Contractor in Ottawa, ON

Ontario requires roofing contractors to be licensed under the Registered Apprenticeship Program (RAP) or hold equivalent credentials. Before hiring, ask for the contractor's license number and verify it directly on the College of Trades website (collegeoftrades.ca) or contact Service Ontario. A valid license confirms the contractor has met training and competency standards required in the province.

In Ottawa specifically, municipal licensing may also apply depending on the scope of work. Always request proof of a current license and verify the expiration date—expired licenses are a major red flag. Don't rely on verbal confirmation; ask for documentation you can independently check. Licensed contractors are more likely to follow building codes and stand behind their work with proper warranties.

Ontario law requires roofing contractors to carry Workers' Compensation coverage (WSIB). Request a Certificate of Clearance or current WSIB account number and verify it at wsib.on.ca. This protects you from liability if a worker is injured on your property.

You should also require proof of General Liability Insurance (minimum CA$2 million recommended) and property damage coverage. Ask contractors to provide a certificate of insurance listing your address as 'additional insured.' This ensures you're protected if the contractor or their crew damages your home, gutters, or landscaping during the project. Never hire a contractor who claims they 'don't need insurance' or can't provide proof—this is one of the biggest warning signs in Ottawa's market.

Obtain at least three written quotes from different contractors before making a decision. A detailed estimate should break down materials (shingles, underlayment, flashing, etc.), labor, cleanup, and warranty terms. Ottawa roofing projects typically range from CA$8,000–CA$20,000+ depending on roof size, pitch, and material choice (asphalt vs. metal vs. cedar).

Be cautious of quotes significantly lower than others—this often signals cut corners, cheap materials, or hidden fees. Ask each contractor to itemize their estimate and explain what's included and excluded. Compare warranties carefully; many Ottawa contractors offer 5–10 year workmanship guarantees plus manufacturer warranties on materials. Don't choose based on price alone; the cheapest option frequently leads to poor outcomes and costly repairs later.

Several warning signs should eliminate a contractor from consideration. Avoid anyone who demands full payment upfront, pressures you to sign immediately, or won't provide written contracts. Legitimate contractors request a deposit (typically 25–33%) upon signing and final payment after inspection and completion.

Other red flags include no physical office address (PO boxes don't count), reluctance to provide references, no online presence or reviews, unmarked vehicles, and crews that lack safety equipment or proper signage. In Ottawa's competitive market, reputable contractors are transparent, responsive, and happy to provide documentation. If a contractor avoids questions, has multiple negative reviews mentioning payment disputes or poor work, or can't explain their process clearly, move on.

If you're filing a home insurance claim for roof damage (storm, ice dam, tree damage), understand your deductible before hiring. Most Ottawa homeowners have a deductible between CA$500–CA$2,500. Your insurance covers repairs only after you pay the deductible.

Some contractors offer to waive or cover your deductible, but verify this is legal in Ontario before agreeing—this practice is heavily regulated. Always get written pre-approval from your insurer before starting work. Document damage with photos and get a damage assessment from your insurer. When requesting quotes, inform contractors whether insurance is covering the work; some may adjust their estimate accordingly. Honest contractors will help navigate the claims process but won't pressure you into unnecessary repairs or promise to 'fight' your insurer.
