Confirm the existing condition
Gather roof history, leak records and prior repair details. Ask which observations support a restoration approach and which conditions need further investigation before the scope can be selected.
Compare preparation and exclusions
Separate surface preparation, local repairs, drainage work and the proposed finish system. Ask what is excluded and how discovered wet or damaged components would change the proposal.
Define the handoff
Request the product information, accepted scope, inspection record and maintenance requirements relevant to the chosen assembly. Verify written warranty terms for that exact system.
