How to Choose the Best Roofing Contractor (10-Point Checklist)

Licence checks, insurance certificates, warranty tiers and the contract red flags that separate a real roofing company from a storm chaser.

Verify before you compare price

Price only means something once you know the company can stand behind the work in five years.

  • Active state, provincial or municipal licence number — ask for it and look it up
  • Certificate of insurance sent directly from the insurer, covering liability and workers' compensation
  • A physical local address, not just a mobile number and a magnet sign
  • Manufacturer certification if a long system warranty is being promised
  • Recent reviews tied to completed jobs, with photos

Questions that expose a weak bid

  • How did you measure my roof, and can I see the measurements?
  • What happens if you find rotten decking — what is the per-sheet price?
  • Which underlayment and ice-and-water coverage are included?
  • Is the crew employed by you or subcontracted, and who supervises daily?
  • What exactly does your workmanship warranty cover, and is it transferable?

Contract red flags

  • A deposit above 30% of contract value, or full payment up front
  • Pressure to sign today for a discount that expires tonight
  • No written scope, no itemisation, no start and completion dates
  • An offer to "cover your deductible" — that is insurance fraud in most jurisdictions
  • Refusal to provide the insurance certificate directly from the carrier

Frequently asked

How many roofing quotes should I get?
Three. Fewer and you cannot see the market; more and the quotes start blurring together without new information.
Should I hire the cheapest roofer?
Rarely. The cheapest bid is usually cheap because it skips tear-off, uses builder-grade underlayment or omits flashing replacement. Compare scope, then price.
Are storm-chasing roofers always bad?
Not always, but out-of-town crews are gone when a workmanship issue appears in year three. Prefer companies with a permanent local presence.
