The fastest way to make a roofing decision safer is to slow down the hiring step: verify the business, compare written scope and understand who is responsible before money changes hands.
1. Start with a written estimate
The Government of Alberta recommends getting written estimates and says the estimate should describe the work, materials, start and completion dates, itemized costs, total price, guarantees and payment method. For roofing, add tear-off depth, disposal, underlayment, flashing, ventilation, decking allowances and cleanup.
Do not compare only the bottom-line number. A detailed $18,000 scope can be more transparent than a $15,000 quote that leaves major items open-ended.
2. Check insurance and WCB status
Alberta’s contractor-hiring guidance tells consumers to ask for evidence of liability and property-damage insurance and to check Workers’ Compensation Board coverage. WCB-Alberta provides clearance letters that show whether a contractor has coverage and whether the account is in good standing.
WCB says a clearance should be obtained before hiring and before releasing payment. Homeowners should confirm how WCB rules apply to their situation rather than assuming a contractor’s business card proves coverage.
3. Understand prepaid-contractor rules
Alberta has special rules for businesses that take money before work is complete and negotiate or conclude the contract away from their normal place of business, such as at your home. The province describes these as prepaid contractors and says licensing and security requirements can apply.
If a salesperson is asking for a deposit at your door or kitchen table, check the current provincial licensing information instead of relying on the salesperson’s explanation of the rule.
4. Ask who will actually do the work
The company that sells the job may use employees, subcontractors or a mix. Ask who supervises the site, who is responsible for safety, who handles warranties and who you call if something is damaged or incomplete.
Subcontracting is common and is not automatically a problem. The important point is that the written contract and insurance/WCB checks match the people and businesses actually involved.
5. Review references and project fit
A roofer who is excellent at straightforward asphalt replacements may not be the right fit for a complex low-slope transition, specialty metal roof or structural repair. Ask about projects similar to yours and what the contractor expects to be difficult on your roof.
When checking references, ask specific questions: Was the final price close to the signed scope? Were changes approved first? Was the property protected and cleaned? How were warranty questions handled?
6. Do not let storm urgency erase the checklist
Hail events can create a rush of inspections, insurance calls and door-to-door marketing. Alberta’s consumer guidance specifically warns about contractors who show up saying they happen to be working in the area and can offer a special price.
An urgent leak may need temporary protection immediately. The permanent replacement decision can still use a written scope, business checks and a clear payment schedule.
8. Ask the same final questions before signing
Who orders the material? Who pulls any permits that apply? Who protects the driveway and landscaping? Who removes debris? What happens if weather delays the project? Which warranty covers workmanship, and which warranty comes from the manufacturer?
These questions are less glamorous than choosing a shingle colour, but they are the details that usually decide whether a roofing project feels organized. A strong contractor should be comfortable putting the answers in writing.
7. Make the payment schedule match visible progress
A deposit can be normal, but the contract should explain how much is due, what it covers and when later payments become due. Avoid a vague agreement that lets the entire balance become payable before the promised work is finished.
If hidden conditions change the price, use written change orders or another documented approval process. A text message can help create a record, but the safest approach is to make sure the contract itself explains how changes are authorized and priced.
Use the first conversation to test clarity
A good initial call should leave you with a clearer understanding of the project, not just a price appointment. Notice whether the company asks about roof age, leak history, storeys, material, storm involvement, access and timing.
Contractors do not need every answer before visiting, but thoughtful questions are a better signal than immediately promising a universal square-foot rate without seeing the roof.
