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

In Ontario, roofing contractors are regulated under the Home Renovation Consumers Protection Act (HRCPA). Any contractor performing roof work valued over CA$500 must be registered with Home Renovation Registry Ontario (HRRO) and hold a valid license. Before contacting any roofer in Cambridge, always verify their HRRO registration on the official registry website. This is your first and most critical step.

Check not only that they're registered, but also confirm their license status is active and hasn't been suspended or revoked. Legitimate contractors in Cambridge will provide their HRRO registration number upfront without hesitation. If a contractor avoids this topic or claims they're exempt, walk away. Additionally, ask if they hold any industry certifications from manufacturers like GAF, Owens Corning, or IKO. These demonstrate ongoing training and access to product warranties.

Never hire a roofing contractor without proof of comprehensive general liability insurance and current Workers' Compensation coverage. Roofing is high-risk work—if an employee is injured on your property and the contractor lacks WSIB coverage, you could be held liable. Request certificates of insurance directly from their broker (not just a copy they provide) showing minimum coverage of CA$2 million in liability.

Ask specifically about course of construction liability if you're having major work done. Review the certificates to ensure they list your address as a job site and that coverage is current. In Cambridge's residential market, expect quotes from qualified contractors to reflect these insurance costs—if a quote seems dramatically cheaper, insufficient insurance is likely the reason.

Obtain at least three written quotes from different roofing contractors in Cambridge before deciding. A proper estimate should specify the roofing material (asphalt shingles, metal, composite, etc.), square footage being replaced, labour costs, disposal fees, timeline, warranty details, and payment schedule. Compare line-by-line, not just total price. A quote that's significantly lower than others may indicate inferior materials, rushed workmanship, or hidden costs that appear later.

Ask whether quotes include removal of old roofing material and disposal—this often costs CA$1,500–CA$3,000 depending on roof size and complexity. Clarify whether the estimate covers ventilation inspection, flashing replacement, and any structural repairs discovered during work. Reputable contractors will be transparent about what could inflate costs mid-project. Verify the warranty covers both materials and workmanship for at least 5–10 years, and whether they warranty their labour separately from manufacturer guarantees.

Ask for at least three references from residential customers in Cambridge or nearby areas within the past 12 months—not from 5 years ago. Contact these customers directly and ask about the quality of work, timeline adherence, site cleanliness, and whether there were unexpected issues or cost overruns. Check Google, Homestar, and Yelp for patterns in reviews, but be aware that disgruntled reviews about price disputes are common in roofing.

Verify that the contractor hasn't been the subject of complaints with the Ontario Home Warranty Plan (OHWP) or legal claims. Search the Better Business Bureau (BBB) database for Cambridge roofing contractors and note their rating, complaint history, and how they respond to complaints. A contractor with a few critical reviews but documented professional responses is often more trustworthy than one with no reviews at all. Be cautious of contractors with multiple unresolved complaints about delayed completion or insurance disputes.

Steer clear of roofers who demand full payment upfront or before the work is complete. Standard payment schedules in Cambridge typically involve 25–30% down to order materials, 50% at mid-project, and final payment upon completion and inspection. Never pay cash, and insist on a formal contract that specifies payment milestones.

Other critical red flags include contractors who are reluctant to provide references, quote by phone without a site visit, offer a quote valid for only 24–48 hours, or claim they have 'leftover materials' from another job at a discount. Beware of contractors offering to bill your home insurance deductible to you directly—this is illegal in Ontario and is a sign of insurance fraud. Similarly, avoid anyone suggesting you misrepresent the scope of work on your claim. Finally, if a contractor approaches you door-to-door after a storm offering emergency repairs at a discount, request time to get competing quotes and verify their credentials before agreeing.
