Identify the business you are hiring
Ask for the legal business name and Oregon CCB number before comparing bids. Check the license record and match it to the contract. If a salesperson uses a brand or trading name, ask which legal entity will take payment and perform the work.
Check insurance and relevant experience
Request current insurance documentation and ask how it covers the proposed work. Ask who employs or supervises the crew and who handles subcontractors. Request references for projects with a similar roof assembly, access constraints, and scope; a photograph alone cannot tell you how the job went.
Make the estimates comparable
Ask every bidder to price the same measurements, material specifications, tear-off, decking, flashing, ventilation, cleanup, and disposal. Compare exclusions alongside the total. A quote comparison checklist can help you identify where the scopes differ.
Agree on changes, payments, and scheduling
Get the scope, payment stages, proposed dates, and change-approval process in writing. Ask how the contractor will document hidden damage and obtain your approval for extra work. Confirm the plan for protecting exposed areas if weather interrupts installation. Avoid relying on verbal promises that do not appear in the agreement.
Assign permit responsibilities
Check whether the project needs permits before setting the start date. Agree who will submit applications, pay applicable fees, arrange inspections, and give you the completion records. Verify any historic or other property-specific review separately.
Read both warranties
Compare the installer warranty with the manufacturer warranty. Ask about exclusions, claim procedures, transfer terms, and registration. Manufacturer certification can affect eligibility for some warranties, but the bid must identify the actual coverage being offered.
Take time to resolve unanswered questions
Pressure to sign, unclear payment instructions, and missing documentation warrant a pause. Our contractor warning signs explain questions to ask without judging a business solely by its size or address. Keep the bid, contract, changes, photos, and completion documents together.
