Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos from Carrickfergus (BT38) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for uPVC roof lantern repairs?
- Green algae along the bars

- Leaks at the ridge or eaves
Common causes we find
Clip failure
Clip-on cappings can lose their grip and lift.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Covering Carrickfergus and nearby
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.
We cover Carrickfergus as part of County Antrim, about 10 miles from Belfast.
If you're just outside Carrickfergus, we also cover Holywood (5 miles), Newtownabbey (6 miles), Bangor, Down (7 miles).
How much should it cost?
Guide price for uPVC roof lantern repairs: £175–£595 ex VAT (£210–£714 inc VAT), per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Northern Ireland?
In Northern Ireland, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations (Northern Ireland) 2012, so we set out the route in writing first. 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.
