Where a roof meets a wall, water management depends on the connection between roofing and wall construction. A surface bead of sealant is not a substitute for understanding how those layers overlap and drain.
What to do next
Ask the roofer to identify which flashing or wall detail is failing and whether another trade must participate. The written scope should describe access, restoration of disturbed finishes, and responsibility for the complete junction rather than only the exposed seam.
