Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from Larne (BT40) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Leaks at the ridge or eaves
Why it happens
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Larne and nearby
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
