A returning stain may reflect continuing moisture, residual discoloration, or a separate source. Painting is a finish repair, not evidence that the roof or other water source has been corrected.
What to do next
Note whether the area feels newly damp without disturbing damaged materials. Compare the timing with rainfall and mechanical-system operation. Ask the relevant professionals to verify the source and drying condition before another cosmetic repair hides the evidence.
