01
Log relevant activity
Record dates and locations of chimney, gutter, window, lighting, communications, and mechanical work near the roof. Include the contractor's scope and any access arrangements. This is a factual maintenance record, not an assumption that a later problem was caused by that trade.
02
Use the record during investigation
If a new issue appears, share the timeline with the roofing professional so they can examine relevant areas. Keep photographs taken before and after work where available. A clear sequence can help separate pre-existing conditions from changes that need review. It also reminds future contractors about access routes and sensitive roof details before they begin another project.
