Every year, Calgary and Edmonton homeowners hand money to roofing contractors who disappear mid-job, install substandard materials, void manufacturer warranties through improper technique, or simply do work that fails within two years. The roofing industry in Alberta has a higher rate of contractor complaints than almost any other trade — largely because a roof replacement is expensive, the quality of work is largely invisible during installation, and problems often don’t surface until months or years later when the contractor is long gone. how to choose a roofing contractor Calgary?
Knowing how to choose a roofing contractor in Calgary or Edmonton before you sign anything is the single most important decision in the entire roofing process. This guide gives you seven specific things to check — not vague advice, but concrete criteria that separate professional roofing contractors from the ones who cost you more in the long run. how to choose a roofing contractor Calgary?
1. Verify WCB Coverage and Liability Insurance — Before the First Meeting
This is non-negotiable and must be confirmed before any contractor steps foot on your property.
Workers’ Compensation Board (WCB) coverage protects you if a worker is injured on your property during the project. Without it, you — as the property owner — can be held financially liable for injuries sustained by workers on your roof. The Alberta government’s guidance on hiring contractors is clear: make sure the contractor and all tradespeople have WCB coverage, and ask for the WCB number before work begins. CMHC
Liability insurance covers damage to your property caused by the contractor’s work — a dropped tool through a skylight, a ladder denting a vehicle, water damage from an improperly tarped roof during a rainstorm. Ask for a certificate of insurance showing a minimum of $2 million in public liability and property damage coverage.
Any contractor who hesitates, deflects, or claims these don’t apply to them is a contractor you walk away from immediately.
At Laser Cut Roofing: We carry full WCB coverage and $2M+ liability insurance on every project. Documentation provided on request before any work begins.
2. Check Their Alberta Licensing and Prepaid Contractor Status
Alberta has specific licensing requirements for contractors who collect deposits or payment before work is complete — which describes virtually every roofing project.
Contractors in Alberta who accept money before work is complete and finalize contracts away from their normal place of business are considered prepaid contractors. They must be licensed by Service Alberta and post a security. You can verify a contractor’s prepaid contracting licence status through Service Alberta before signing anything. CMHC
Additionally, confirm that the tradespeople actually installing your roof are qualified. In Alberta, a qualified tradesperson will hold a pocket certificate issued by the Government of Alberta — verifiable through Alberta Apprenticeship and Industry Training. Roofing in Alberta is a designated trade, meaning there are established certification standards for journeypersons. You’re entitled to ask whether the crew installing your roof holds recognized trade certification. CMHC
A contractor who can’t confirm licensing and worker certification is a significant red flag — particularly in Calgary and Edmonton where post-storm surge hiring brings unqualified out-of-province crews into the market every summer.
3. Ask for a Manufacturer Certification — Not Just a Claim of “Quality”
Any roofing contractor can say they do quality work. Very few can prove it with independent third-party manufacturer certification.
IKO RoofPro Select is one of the highest designations available to Canadian roofing contractors — awarded only to companies that meet IKO’s verified standards for installation technique, crew training, and quality practices. It’s not a membership anyone can buy — it’s earned through demonstrated performance and independently verified.
Why does this matter to you practically? Because manufacturer warranties — often 25–30 years on premium shingles — are only fully valid when the product is installed by a certified contractor following the manufacturer’s specifications. A non-certified contractor can install IKO shingles, but if they do so incorrectly, the manufacturer warranty is voided. You’re left with a product warranty that exists on paper but can’t be enforced when you need it.
When comparing quotes, ask every contractor whether they hold current IKO RoofPro Select certification or equivalent. If they can’t confirm it or don’t know what it is, your manufacturer warranty is at risk regardless of what the quote says.
At Laser Cut Roofing: We are IKO RoofPro Select certified — independently verified. Every IKO installation we complete preserves the full manufacturer product warranty.
4. Read the Warranty Terms — All of Them
There are two separate warranties on any professional roofing installation and most homeowners only think about one.
Manufacturer product warranty covers defects in the roofing material itself — shingles, membrane, underlayment. This is what contractors typically advertise as “30-year shingles.” Read the fine print: most manufacturer warranties are prorated, meaning they pay diminishing percentages as the roof ages, and most are voided by improper installation.
Workmanship warranty covers the contractor’s installation quality — the flashing, sealing, underlayment, ventilation, and every other installation decision the crew makes. This is the warranty that actually matters for the most common failure causes, because most roofs don’t fail due to material defects — they fail due to installation errors.
A contractor offering no workmanship warranty, or a workmanship warranty shorter than 5 years, is telling you something important about their confidence in their own work. A professional contractor stands behind their installation for a minimum of 5 years — the best contractors offer 10.
Ask for both warranties in writing before signing. If the contractor can’t produce written warranty documentation, don’t proceed.
At Laser Cut Roofing: Every installation carries a 10-year workmanship warranty in writing — separate from and in addition to manufacturer product warranties.
5. Get a Written, Itemized Quote — Not a Verbal Ballpark
The quote you receive before signing a contract is your only protection against cost surprises during the job. A professional roofing contractor provides a written, line-itemized quote that specifies:
- Exact materials being used — brand, product line, colour, specification
- Whether existing layers are being torn off or installed over
- Deck repair allowance or confirmation of deck inspection
- Underlayment type and coverage
- Ice and water shield coverage — specifically whether it meets Alberta Building Code minimum requirements
- Flashing scope — chimney, skylight, valley, wall intersections
- Ventilation — confirmation it meets code specifications
- Disposal and cleanup
- Permit responsibility — who pulls it and who pays for it
- Timeline
- Payment terms
- Both warranty terms in writing
A written estimate should include a complete description of the work that will be done, the type and quality of materials to be used, and a statement of any work to be subcontracted. CMHC
If a contractor provides only a total number without line items, you have no way to compare quotes meaningfully or hold them accountable for what was agreed. Get it in writing or walk away.
6. Watch for These Red Flags — They Cost Alberta Homeowners Thousands Every Year
Not every red flag is obvious. Here are the specific ones most commonly reported in Calgary and Edmonton:
Door-knocking after a hailstorm Storm-chasing crews descend on Calgary and Edmonton within days of major hail events. They knock doors, claim your roof is severely damaged, pressure you into signing on the spot, and often demand a large deposit before starting work. Many are from out of province, operating temporarily, and gone before any warranty issues surface. If a contractor knocked your door unsolicited after a storm — get independent verification of any damage before signing anything.
Asking for large upfront deposits A reasonable deposit for a residential roofing project is 10–30% of the total contract value. Any contractor requesting 50% or more upfront — especially before materials are even ordered — is a serious red flag.
No local permanent office A P.O. box or a cell number is not a local business. Verify the contractor has a real physical office address in Calgary or Edmonton that you can visit and that will still be there if you need warranty work in year three.
Installing over existing shingles Ask directly: are you tearing off the existing roof? A contractor who proposes installing over existing layers without a specific structural reason is cutting costs at your expense — and likely voiding the manufacturer warranty in the process.
Permit avoidance If a contractor suggests skipping the permit to “save money,” decline. Permits exist to ensure the work is inspected and meets Alberta Building Code standards. Unpermitted work can affect your home insurance coverage and create problems when you sell the property. See the Alberta Safety Codes permit requirements for what applies to your project.
No verifiable reviews Check Google, HomeStars, and BBB independently — not just the testimonials on the contractor’s own website. A company with 15+ years in Calgary or Edmonton should have a meaningful, verifiable review history. If you can’t find independent reviews, that’s an answer in itself.
7. Confirm They Have Permanent Local Presence in Calgary or Edmonton
This is the check most homeowners skip — and the one that matters most when something goes wrong two years after the job is done.
A roofing contractor based permanently in Calgary or Edmonton has skin in the game. Their reputation lives in the same community as their clients. Their crew is local, their office is real, and they’ll still be there when you call about a warranty issue in year four.
An out-of-province storm chaser or a contractor with no verifiable local address has none of that accountability. Once the job is done and payment is collected, there’s no practical mechanism to enforce warranty claims against a company that no longer has a local presence.
Before signing, confirm: the contractor’s physical office address, how long they’ve operated from that address, and whether they can provide references from Calgary or Edmonton projects completed in the past two years — not just a generic testimonials page.

Frequently Asked Questions
How many quotes should I get for a roof replacement in Calgary? Get a minimum of three written quotes from contractors who each performed a site visit. Comparing quotes without site visits is comparing guesses — deck condition, exact square footage, and complexity can only be assessed in person. Three quotes gives you a meaningful price range and reveals any contractor whose number is suspiciously low or high.
Is the cheapest roofing quote always the wrong choice? Not always — but a quote significantly lower than the others almost always reflects something missing: cheaper materials, no permit, no tear-off, lower warranty coverage, or subcontracted labour. Understand what’s different before assuming a low quote is a good deal.
What should I do if a roofer knocks my door after a hailstorm? Don’t sign anything on the spot. Get your own independent inspection first — from a contractor you found yourself, not one who approached you. Then contact your insurance company to report potential damage. See our complete hail damage guide → for the full step-by-step process.
Do roofing contractors in Alberta need to pull permits? For most roofing projects in Alberta, yes — a permit is required under the Safety Codes Act. A professional contractor manages this on your behalf. See the Alberta Safety Codes permit guide for specifics on what requires a permit in your municipality.
How do I verify a contractor’s WCB coverage in Alberta? Ask the contractor for their WCB account number and then verify it directly through WCB Alberta at wcb.ab.ca. This takes two minutes and is always worth doing before any work begins on your property.
