The eaves beam is the frame around the base of a lantern, and most designs have a drainage channel inside it that lets water out through small weep slots. Send photos from Machynlleth (SY20) and we'll tell you which it is — with the price agreed in writing before any work.

Why it happens
Blocked weep slots
Debris settles at the eaves and blocks the outlets, so the channel fills and overflows inward.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Roof lanterns in Machynlleth
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
