Wall staining below a roof edge can indicate water following an unintended path, but staining alone is not a diagnosis. Gutters, edge details, joints, and wall finishes may all need consideration. Repainting without investigation can hide useful evidence.
What to do next
Photograph the pattern and note rainfall conditions. Ask for a review of the water path and affected materials. Keep drainage correction and finish restoration coordinated so the same condition is not simply concealed beneath new paint.
