A simple sketch can help connect interior damage with roof features. Label the affected room, exterior walls, nearby vents, and the direction of the visible stain. Keep measured observations separate from guesses about the source.
What to do next
Photograph from the same safe position after different rain events. Include dates and mark whether the spot is new, unchanged, or expanding. Share the sketch with the roofer; it supports an inspection but cannot replace examination of the roof assembly.
