We carry out roof lantern replacement in Risca and across the NP11 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.

Signs you need roof lantern replacement
- Distorted or sagging frame
- 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.
Structural damage
Impact or movement distorts the frame.
Covering Risca 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.
We cover Risca as part of Gwent, about 5 miles from Newport, Gwent.
If you're just outside Risca, we also cover Newport, Gwent (5 miles), Cwmbran (5 miles), Caerphilly (6 miles).
How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc 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 Wales?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
