Build a leak timeline
Record when the leak appears, whether rain is wind-driven, whether rooftop equipment was recently serviced and which interior rooms are affected. Name each location on a floor plan so the roofing and facilities teams can compare observations.
Ask for a repair scope you can revisit
- Observed defect and how it was investigated.
- Compatible repair materials and detail treatment.
- Nearby areas inspected and conditions still unresolved.
- Photographs and follow-up checks after repair.
A temporary response and a permanent repair should be identified separately. Review what to do when a commercial roof leaks for the initial information to collect.
Avoid changing the surface before diagnosis
Unrecorded patching can hide clues and introduce another material into the assembly. Ask a qualified contractor to verify the existing membrane and proposed repair compatibility. Seams, penetrations and flashings deserve their own detail review.
This is planning information, not a site assessment or installation procedure. Use current product documents, qualified personnel and site-specific requirements for a project decision.
