Understand the proposed work
Ask: What is included? What material and product will be installed? How will flashing and ventilation be addressed? Keep each contractor’s answers with the written proposal so the scopes can be compared directly.
Clarify changes and project logistics
Ask: How will hidden damage or changes be approved? Where will materials and debris be placed? Agree on how unexpected conditions are documented and how any additional cost will be communicated before work proceeds.
Know what happens at the end
Ask: What does cleanup include? What written warranty documentation will I receive? Product coverage and workmanship coverage may differ. Review the actual documents and payment terms, and keep a copy with the final scope.
