Identify the company on the contract
A local office, national brand, or franchise name does not establish who is responsible for your work. Match the legal business on the contract to its Oregon CCB license. Ask whether the crew is employed by that company or subcontracted.
Compare project experience
Request references for the same roof assembly and similar access conditions. Ask how the contractor will handle decking, flashing, disposal, and any required approvals. Compare a replacement scope or repair scope on equal terms across companies.
Read the warranty and scheduling terms
Ask who handles callbacks, how to contact them, and what happens if the installer no longer operates. Confirm manufacturer warranty requirements for the actual products and contractor. Get availability in writing rather than assuming one company type will respond faster.
Assess the sales process
Give yourself time to review the bid. Pressure to sign, unclear payment terms, and missing documentation deserve follow-up regardless of where the company is based. Use the hiring guide to compare the evidence.
