The symptom
A brown mark returns near the chimney only after storms with strong wind.
How to reason without overreaching
- The timing supports investigating exterior water paths.
- Cap, crown, masonry, flashing and adjacent roofing all remain candidates.
- One stain location does not prove which exterior component failed.
Reasonable next steps
- Photograph the stain after each event.
- Ask for a whole-intersection leak assessment.
- Compare a repair scope that states the diagnosed path and verification plan.
Actual property conditions may change every conclusion. For immediate danger, leave the affected area and call emergency services.
