How to Choose a Licensed Roofing Contractor in Markham, ON
Finding a trustworthy roofing contractor in Markham is critical—your roof protects your home from Ontario's harsh winters and heavy precipitation, and poor workmanship can lead to costly leaks and structural damage. With numerous contractors operating in the Greater Toronto Area, knowing how to verify credentials, check insurance, and spot red flags will help you avoid costly mistakes. This guide walks you through the essential steps to vet a roofing contractor before signing any contract.

In Ontario, roofing contractors must hold a valid Home Improvement Contractor (HIC) license issued by Consumer Protection Ontario if their project value exceeds CA$10,000. Before hiring anyone, ask for their HIC license number and verify it directly on the Consumer Protection Ontario website—don't rely on their word or a photocopy. A legitimate contractor will have no problem providing proof immediately.
Beyond HIC licensing, check whether the contractor holds a business license from the City of Markham and inquire about any specialized certifications (such as manufacturer-approved credentials for asphalt shingle, metal roof, or flat roof installation). Membership in professional bodies like the Roofing Contractors' Association of Ontario (RCAO) or the Canadian Roofing Contractors' Association is a positive sign, though not mandatory.
Confirm Current Insurance Coverage
Every roofing contractor in Markham must carry Workplace Safety and Insurance Board (WSIB) coverage for their employees and general liability insurance of at least CA$2 million. Request proof of both—specifically, ask to see an active Certificate of Insurance or WSIB clearance certificate. Never allow a contractor to begin work without providing this documentation in writing.
Liability insurance protects you if the contractor's work damages your property, and WSIB coverage ensures workers are protected on your roof, reducing your liability exposure. If a contractor claims they're an independent operator and don't carry these, walk away immediately—they're operating illegally in Ontario.
Get Multiple Quotes and Compare Carefully
Always request at least three written quotes from different contractors in Markham. A detailed quote should specify the scope of work, materials, timeline, warranty terms, deductible applicability (if working with insurance), total cost, and payment schedule. Quotes that are significantly lower than others warrant investigation—this often signals inferior materials, rushing, or inexperienced workers.
When comparing quotes, don't focus solely on price. Examine the warranty offered—reputable contractors typically provide a minimum 5-year workmanship warranty and pass through manufacturer warranties (often 20–30 years on shingles). Ask whether the warranty covers labor, materials, or both, and whether it's transferable if you sell your home. Request references from recent projects in Markham and follow up by calling at least two homeowners to ask about quality, timeliness, and how the contractor handled issues.
Check References, Reviews, and Complaint History
Request a list of at least three local Markham references from projects completed in the past 12 months. Call these homeowners and ask specific questions: Was the work completed on time? Were there any unexpected costs? How did the contractor handle cleanup? Would they hire this contractor again? Online reviews on Google, Trustpilot, and the Better Business Bureau (BBB) provide additional insight, though read reviews critically—focus on recurring themes rather than isolated complaints.
Search the Consumer Protection Ontario database and BBB for any unresolved complaints or disciplinary history. A contractor with numerous unresolved disputes is a risk. If you're considering a contractor from outside Markham, verify they're insured to work in Ontario and have experience with local climate conditions (freeze-thaw cycles, heavy snow loads, and wind exposure in the GTA).
Critical Questions to Ask Before Hiring
- How long have you been in business, and are you licensed, insured, and WSIB-covered? (Verify independently.)
- What is your warranty on workmanship and materials, and does it cover labor, parts, or both?
- Will you handle roof disposal and cleanup, or is that a separate cost?
- Do you pull permits for this project, and who's responsible for inspection fees?
- How do you handle changes or unexpected damage discovered during the project?
- What is your payment schedule—do you require a deposit, and what's your policy on holding final payment until completion?
- Are you familiar with working with homeowner insurance claims, and will you coordinate with the adjuster?
- Can you provide a written project timeline and explain what causes delays?
Red Flags to Avoid
Several warning signs indicate you should look elsewhere. Contractors who demand 50% or more upfront, refuse to provide references or insurance proof, offer a quote over the phone without inspecting your roof, or pressure you to decide immediately are operating outside professional standards. Beware of door-to-door solicitors claiming your roof is damaged—many are high-pressure sales tactics from out-of-area operators.
If a contractor quotes significantly below market rates (typically CA$7,000–CA$15,000 for a standard asphalt shingle roof in Markham), ask why—they may cut corners on materials, skip underlayment, or abandon the project mid-way. Avoid contractors who won't put their quote and warranty in writing or who only accept cash payments. Finally, if they dismiss your insurance company's assessment or suggest inflating a claim, move on—this signals unethical practices that could expose you to fraud liability.
Frequently Asked Questions
Do I need a permit for a roof replacement in Markham?
Yes, most roof replacements in Markham require a building permit from the City of Markham, particularly if you're replacing more than 25% of the roof area or changing the roof type. A licensed contractor should pull the permit and ensure a municipal inspection upon completion. Skipping permits can result in fines, insurance claim denial, and difficulty selling your home. Always confirm with the contractor that permits will be obtained before work begins.
How does my insurance deductible apply to roof damage claims?
If your roof is damaged by wind, hail, or weather events covered by your policy, your insurer will cover the cost minus your deductible (often CA$500–CA$2,500). You pay the deductible; the insurer pays the rest (up to your coverage limit). When obtaining contractor quotes, ask them to provide an estimate both with and without insurance involvement, so you understand your out-of-pocket cost if you file a claim.
How can I verify a contractor's HIC license in Ontario?
Visit the Consumer Protection Ontario website (ontario.ca/page/home-improvement-consumer-protection) and search the Home Improvement Contractor database by license number or company name. The search result will show whether the license is active, any complaints, and disciplinary history. Always verify independently rather than accepting the contractor's claim—this is free and takes two minutes.
What's the typical cost of a roof replacement in Markham?
A standard asphalt shingle roof replacement on a two-story home in Markham typically ranges from CA$8,000–CA$15,000, depending on roof size, slope, complexity, and material choice. Metal or premium shingle roofs cost more. Always get multiple quotes to establish realistic pricing for your specific home. Be cautious of quotes significantly below or above this range without clear explanation.
Can a contractor work on my roof if they're not from Markham?
Yes, contractors from anywhere in Ontario can work in Markham as long as they hold a valid HIC license, current insurance, and WSIB coverage. However, prioritize contractors familiar with Markham's climate (freeze-thaw cycles, heavy snow) and local building codes. Verify they've completed similar projects in the GTA and ask about their timeline if they're traveling from further away, as weather delays could extend the project.
