Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos from Barry (CF62) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Flaking or blistered paint on bars or eaves
- Soft timber when pressed
- Putty or beads cracking and lifting
Why it happens
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
No maintenance
Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
Covering Barry 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.
From Cardiff to Barry is roughly 7 miles — all part of the South Glamorgan area we cover.

What should you expect to pay in Barry?
Most timber roof lantern repairs jobs come in between £395 and £1,995 ex VAT (£474–£2,394 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?
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.
