Choosing the right commercial roofing contractor is as important as choosing the right roof system. Here's what to look for — and what to avoid.

Essential Qualifications

Licensing

  • Verify active contractor's license in your state
  • Check for any disciplinary actions
  • Ensure license covers commercial roofing

Insurance

Request certificates of insurance for:

  • <strong>General liability:</strong> $1M+ per occurrence

  • <strong>Commercial auto:</strong> If vehicles on your property

Manufacturer Certifications

Look for contractors certified by major manufacturers:

  • GAF Master Select

Red Flags to Watch For

Avoid contractors who:

  • Demand large upfront deposits (10-20% is reasonable)
  • Can't provide local references
  • Pressure you for immediate decisions
  • Only offer verbal quotes
  • Don't pull permits

Questions to Ask

1. How long have you been in business?

2. Can you provide 5 local references?

3. What warranties do you offer?

4. Who will supervise my project?

5. How do you handle change orders?

6. What's your safety record?
