We carry out aluminium roof lantern repairs in Llanelli and across the SA15 area. Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear.
What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Misted units
What usually causes it?
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Covering Llanelli 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.
From Carmarthen to Llanelli is roughly 13 miles — all part of the Dyfed area we cover.
We also cover nearby Gorseinon (5 miles), Swansea (10 miles), Ammanford (11 miles).
Guide prices for aluminium roof lantern repairs in Llanelli
Typical range: £195–£695 ex VAT, which is £234–£834 with 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.
