Hiring the wrong roofing contractor is one of the most expensive mistakes a Vancouver homeowner can make. A poorly installed roof leads to leaks, voided warranties, insurance issues, and repair costs that often exceed the original job. The roofing industry in British Columbia has a wide range of operators, from licensed professionals with decades of experience to unlicensed crews doing cash jobs on the side.
This guide covers exactly what to look for, what to avoid, and how to evaluate a roofing contractor before signing a contract in the Greater Vancouver area.
Verify Licensing and Insurance First
In British Columbia, roofing contractors are required to hold a valid business license and carry liability insurance. WorkSafeBC coverage is mandatory for any company with employees working on your property. Before hiring anyone, ask for their business license number, proof of general liability insurance (minimum $2 million is standard for residential work), and their WorkSafeBC account number.
If a contractor cannot or will not provide these documents, do not hire them. An uninsured contractor working on your roof puts you at personal financial risk if a worker is injured on your property or if the work causes damage to neighboring properties.
Check Their Track Record in Vancouver Specifically
Roofing in Vancouver is different from roofing in Calgary, Toronto, or anywhere with a different climate profile. You want a contractor who understands local conditions: heavy rainfall, moss growth cycles, Pacific storm wind loads, and the specific building codes enforced by your municipality (Vancouver, Surrey, Burnaby, and New Westminster each have their own permitting requirements).
Ask how long they have been operating in the Lower Mainland, how many roofs they complete per year in this area, and request references from past clients in your neighborhood or city. A contractor with 10 years of experience in Alberta but 6 months in Vancouver is not as qualified for your job as one with 5 years of dedicated local experience.
Get Multiple Written Estimates
Always get at least three written estimates before making a decision. Each estimate should include a detailed scope of work (not just a total price), the specific materials to be used (brand, product line, and warranty tier), the timeline for completion, payment terms, and what happens if additional work is discovered during the project (such as decking replacement).
Be wary of any estimate that is significantly lower than the others. In roofing, a low price usually means lower-quality materials, fewer layers of underlayment, shortcuts on flashing and ventilation, or an unlicensed operator trying to undercut the market. The cheapest option almost always costs more in the long run.
Ask About Warranties: Workmanship vs. Manufacturer
There are two types of warranties on a roofing job: the manufacturer warranty (which covers defects in the roofing material itself) and the workmanship warranty (which covers the quality of the installation). Both matter, but the workmanship warranty is the one most homeowners overlook.
A good roofing contractor in Vancouver should offer a minimum 5-year workmanship warranty, with 10 years being the standard among top-tier companies. The manufacturer warranty is only as good as the installation. If a roof leaks because of poor flashing work, the manufacturer will not cover the damage even if the shingles are under warranty.
Look at Reviews but Read Them Critically
Google reviews are a useful starting point, but they should not be your only evaluation tool. Look for contractors with at least 20 to 30 reviews and an average rating of 4.5 or higher. More importantly, read the detailed reviews. Look for mentions of how the contractor handled problems (because every project has some), whether they communicated clearly throughout the process, and whether they cleaned up properly after the job.
Be cautious of contractors with only 5-star reviews and no detailed feedback. Genuine review profiles include a range of experiences. A contractor who responds professionally to critical reviews demonstrates accountability.
Red Flags to Watch For
Avoid any roofing contractor who pressures you to sign immediately or offers a special deal that expires today. Walk away from contractors who want a large deposit upfront (more than 10 to 15 percent of the total job), who do not have a physical business address in the area, who refuse to pull permits for work that requires them, or who only accept cash.
Storm chasers are another common issue in the Lower Mainland. These are out-of-area crews who show up after major weather events, offer low prices, do substandard work, and leave before warranty claims can be filed. Always verify that your contractor has a permanent local presence.
Questions to Ask Before Signing a Contract
Before you commit, ask these questions: Will you pull the necessary permits for this job? Who will be the on-site supervisor? What is your process for handling unexpected issues or change orders? Can I see photos of recent projects similar to mine? What is included in your cleanup process? Do you carry both general liability insurance and WorkSafeBC coverage?
A professional contractor will answer all of these questions directly and without hesitation. If you get vague answers or pushback, consider it a warning sign.
Frequently Asked Questions
How much should I pay upfront for a roofing job in Vancouver?
A reasonable deposit is 10 to 15 percent of the total contract value. This covers initial material ordering. Be cautious of any contractor requesting 50 percent or more before work begins.
Do I need a permit for roof replacement in Vancouver?
In most municipalities in the Lower Mainland, a building permit is required for full roof replacement. Your contractor should handle the permit application as part of the project. Re-roofing over existing shingles may have different requirements depending on the municipality.
What is a reasonable workmanship warranty for a roofing contractor?
The industry standard among reputable contractors in Vancouver is 5 to 10 years for workmanship. Some premium contractors offer 15 to 25 year workmanship warranties. Be sure to get the warranty terms in writing before the project starts.
Should I choose the cheapest roofing estimate?
No. The cheapest estimate is often the most expensive decision in the long run. Low bids usually indicate lower-quality materials, shortcuts in installation, or an unlicensed operator. Compare estimates based on scope, materials, warranty, and contractor reputation rather than price alone.
