Visible boundary
Photograph the full surface and the newest edge with an orientation reference.
Sheet 37 / Diagnostic set
Compare fixture use, delay, weather timing, active moisture, and electrical proximity.
A stain below plumbing can overlap fixture use, enclosure water, drainage, supply, weather, and other paths. Photograph the edge and build a safe time comparison before access is proposed.

Each note describes an action, not a diagnosis. Leave unsupported branches open.
Photograph the full surface and the newest edge with an orientation reference.
List the toilet, sink, tub, shower, or appliance used before a change.
Estimate the interval from use to dampness rather than assuming immediate travel.
Include rain or snow timing as another branch, not a conclusion.
Stop use and keep away when moisture approaches a fixture, fan, detector, or wiring.
Trace the source
Record each upstairs fixture used, any delay, rain timing, active moisture, light or wiring proximity, and prior repair. The inspecting professional should decide whether and where opening is justified.
Repair route and access map
Retain the confirmed route, access created, plumbing work, moisture limit, electrical or drying referral, restoration owner, and a dated post-work image.
