Ask what coverage the bid includes
A contractor badge alone does not identify the warranty you will receive. Ask for the warranty name, current document, product list, eligibility conditions, registration requirements, and any additional price.
Check the manufacturer’s requirements
Review Owens Corning’s warranty options with the bidder. Its extended warranties depend on qualifying contractor and product requirements; an authorized contractor is not obliged to include an extended warranty in every job. For GAF work, request the current warranty document for the building type and proposed system.
Match the products to the proposal
For a roof replacement, identify the shingles or panels, underlayment, starter, ridge, flashing, and other specified components. Ask the contractor to document any substitutions and their effect on eligibility before approving them.
Read the installer warranty separately
Compare workmanship and material coverage, exclusions, claim procedures, and transfer conditions. Confirm who handles a leak report and what records you should keep. Use the contractor hiring guide to assess the whole agreement.
Request a roofing referral. Availability and response times vary.
