Questions to ask before you sign

  1. Can you show me your license or registration number, and does it match what's on file with the state?
  2. Will you pull the roofing permit yourself, and will you give me the permit number once it's issued?
  3. How many existing layers are on my roof now, and does that allow a recover under the building code, or does it need to come off?
  4. What's the full written scope: materials, brand, quantity, start date, and payment schedule?
  5. What does the manufacturer's warranty cover, separate from your own workmanship warranty?
  6. Who is responsible if a subcontractor or material supplier on my job goes unpaid?
