The seven questions:
- What is your state license number? (Verify it directly on your state contractor licensing board.)
- Can you provide a current Certificate of Insurance from your insurer?
- Are you certified by the manufacturer of the shingles you propose?
- What is your written workmanship warranty?
- What is your payment schedule? (Avoid contractors who demand more than 30% upfront.)
- Will you pull required permits in your name, not mine?
- Can I have three local customer references from the past 6 months?
