Common causes we find

Worn gaskets

Gaskets do the weatherproofing; they harden and shrink with age.

Thermal movement

Aluminium moves with temperature; seals and fixings take the strain.

Roof lanterns in Coleraine

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.

Do you need permission in Northern Ireland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
