Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Tredegar (NP22) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaks at bars or ridge
- Chalky or chipped powder coat
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Covering Tredegar 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.
Tredegar is around 17 miles from Newport, Gwent, and both are within our Gwent coverage.
We also cover nearby Ebbw Vale (2 miles), Merthyr Tydfil (6 miles), Blackwood (7 miles).
How much should it cost?
Most aluminium roof lantern repairs jobs come in between £195 and £695 ex VAT (£234–£834 including 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 Wales?
In Wales, 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 2010 (as applied in Wales), so we set out the route in writing first. 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.
