Roof lanterns in County Down

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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
