A stain is a clue to the route, not always the source
Water can move along framing, pipework or other building elements before it becomes visible. Describe the affected area and what happens above, beside or nearby when moisture appears. The timing of showers, appliance cycles and rain can help distinguish possible sources.
Share previous investigations and where surfaces were already opened. This can prevent the next assessment relying on the same untested assumption. Photographs should show context, and any destructive access should follow a clear purpose rather than simply opening at the centre of a stain.
