Several interior stains can share an upstream water source, but they can also reflect independent defects. Counting stains does not establish the number of roof repairs needed. A coordinated inspection is more useful than treating every room separately.
What to do next
Prepare a building-wide location map and date each observation. Ask the report to connect findings where evidence permits and identify uncertainty where it does not. Compare a targeted repair scope with broader work only after the roof condition has been documented.
