Step 1: Verify Licensing, Insurance, and WCB Coverage

Hiring a reliable roofing contractor in St. Albert starts with paperwork, not curb appeal. A reliable roofing contractor carries valid licensing, liability insurance, and WCB coverage, and will hand over proof without hesitation.

In Alberta, any business charging for roofing work must hold a valid provincial licence. Ask for the licence number in writing and confirm it before signing anything. Alberta’s consumer protection resources for hiring contractors

Insurance matters just as much. Ask for two documents:

• Liability insurance covering property damage and injuries on your site
• WCB coverage protecting you if a worker gets hurt on your roof

Without WCB coverage, an injured worker can come after you as the homeowner.

Step 2: Check Red Seal Certification and Trade Credentials

Red Seal certification is the national standard proving a tradesperson passed a rigorous interprovincial exam. For roofing work, it signals real training, not just a truck and a ladder.

Step 3: Ask the Right Questions to Ask a Roofing Contractor

The best way to separate a professional from a salesperson is a short, direct conversation. Here are the questions to ask a roofing contractor before any money changes hands:

1. Are you licensed, insured, and covered by WCB?
2. Who will actually be on my roof, your crew or subcontractors?
3. Can you provide local references from similar projects?
4. What’s the full project timeline, start to finish?
5. How do you handle unexpected damage once work begins?
6. What warranty covers labor, and what covers materials?

Step 4: Request Detailed Written Estimates and Compare Quotes

A written estimate is your protection against surprise costs. It should list materials by type and brand, labor, disposal fees, and a clear project timeline.

When you compare quotes, look past the bottom line:

Step 5: Evaluate Warranty Coverage and Manufacturer Guarantees

Roof warranties come in two layers, and you need both in writing before a single shingle is removed.

What actually voids a warranty

Manufacturer warranties are conditional, and the conditions are where homeowners get caught:

• Improper installation. Most manufacturers require installation by a certified or preferred installer. An uncertified crew can leave you holding a warranty that will not be honored.
• Poor ventilation. Inadequate intake or exhaust ventilation traps heat and moisture, and manufacturers routinely deny claims where ventilation falls outside their specification.
• Layered shingles. Installing new shingles over old ones instead of a full tear-off can void coverage and shorten the roof’s life.
• Unauthorized repairs. Having a different contractor patch the roof without notifying the manufacturer can void the warranty on the affected area.
• Failure to maintain. Some warranties require documented maintenance, which is one more reason to keep inspection records.

Questions to ask before you sign

1. How long is the workmanship warranty, and is it transferable if I sell the home?
2. Which manufacturer warranty applies to the specific product being installed?
3. Does the labor portion of the manufacturer warranty match the product portion, or is it shorter?
4. What maintenance or registration steps must I complete to keep coverage valid?
5. Who do I call first if something fails, you or the manufacturer?

Step 6: Spot Red Flags and Avoid Roofing Scams

Storm chasers and fly-by-night crews target homeowners after every major hail event. The warning signs are consistent:

• Cash-only payment demands
• No local address or phone number
• Pressure to sign the same day
• Door-to-door “free inspection” offers
• No written contract

Step 7: Understand Permits and Post-Installation Maintenance

Most full roof replacements in St. Albert require a building permit, and a reliable contractor will pull it rather than asking you to. The permit is not paperwork theater: it triggers an inspection of the deck, underlayment, flashing, and ventilation before the finished roof is closed up. Skipping it can surface years later when you sell the home or file an insurance claim, because a buyer’s inspector or an adjuster can flag unpermitted work and force you to open the roof again.

Here is how the process normally runs:

1. Scope check. The contractor confirms whether your job is a repair, a partial replacement, or a full tear-off, since only some repairs are exempt from permitting.
2. Application. The contractor submits the application, site plan, and material specifications to the City of St. Albert’s planning and development department.
3. Permit issuance. You receive a permit number and a posted copy that stays visible on site.
4. Inspections. The city inspects at the stages it requires, typically after the deck and underlayment are exposed, and again at final completion.
5. Final sign-off. The permit is closed only after the final inspection passes. Keep that record with your home documents.

What to confirm before work starts

• The permit is issued in the property owner’s name, not the contractor’s.
• The permit number is written into your contract.
• The contractor knows which inspections apply and who schedules them.
• You receive copies of every inspection report.

Post-installation maintenance checklist

• Spring: Walk the perimeter and look for lifted, cracked, or missing shingles, especially on south- and west-facing slopes that take the most hail and sun.
• Spring: Check attic insulation and ventilation. Poor ventilation traps heat and moisture, which shortens shingle life from the inside.
• Fall: Clear leaves and debris from valleys, gutters, and downspouts before the first freeze. Blocked drainage is a leading cause of ice damming.
• Fall: Inspect flashing around chimneys, skylights, and vents, and re-caulk any cracked sealant before winter.
• After any major hail or wind event: Have the roof inspected rather than waiting for the next scheduled check. Damage often hides in the granular surface and only leaks months later.
• Every two to three years: Book a professional inspection, and keep the written report with your warranty documents.
