In Portadown, as everywhere, we're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos and we'll tell you what we think has failed.

Signs you need roof lantern replacement
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
Why it happens
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Rot
Timber lanterns left unmaintained.
Roof lanterns in Portadown
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.
Portadown is around 10 miles from Armagh, and both are within our County Armagh coverage.
Neighbouring places we cover include Craigavon (3 miles), Lurgan (5 miles), Banbridge (8 miles).
How much should it cost?
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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?
Most lantern repairs in Northern Ireland need no approval at all. Where a job turns into a replacement, the Building Regulations (Northern Ireland) 2012 apply and we confirm how the work will be signed off before we start. 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.
