More than one fault

Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
