A parapet introduces wall surfaces, coping, joints, and roof transitions above the occupied space. Water entry may involve more than the membrane at its base. Focusing only on the roof field can leave the source unresolved.
What to do next
Ask the inspection to include the parapet and its connections where accessible. Identify which trade is responsible for each repair. Compare proposals on whether they address the complete water path rather than sealing only the most visible junction.
