Water can travel along decking, framing, or penetrations before appearing on a ceiling. The stain identifies where water became visible, not necessarily where it entered. A repair based only on the room below can miss the actual defect.
What to do next
Record when the stain grows and which direction rain is coming from. Give the roofer interior photographs and a room sketch. Ask the assessment to connect the suspected entry point with the interior symptom before authorizing a patch.
