ROOF ACCEPTANCE / WARRANTY
Roofing Warranty, Ventilation & Acceptance Guide
Prepare roof acceptance around completed scope, flashing, drainage, ventilation, manufacturer installation requirements, workmanship warranty, documentation and final inspection instead of treating final payment as the only closeout step.
Verify the installed system
- Confirm the installed roof covering, underlayment and accessories match the approved proposal and manufacturer system.
- Inspect flashing, penetrations, valleys, edges and drainage paths before access becomes difficult after closeout.
- Check attic or roof-assembly ventilation and moisture-control details against the project design and applicable code provisions.
Close out evidence
- Collect product identification, warranty registration requirements, contractor workmanship warranty, permits and inspection records.
- Photograph concealed or difficult-to-access details during construction where those records can help later maintenance or warranty work.
- Record approved deviations and change orders so the final installed scope is unambiguous.
Final acceptance
- Complete cleanup and magnetic fastener pickup where applicable before sign-off.
- Resolve punch-list items before releasing the final contractual payment where the contract permits it.
- Retain maintenance requirements and warranty exclusions with the property records so later work does not accidentally void coverage.
