We carry out timber roof lantern repairs in Dolgellau and across the LL40 area. Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber.
What you might be seeing
- Flaking or blistered paint on bars or eaves
- Dark staining or black lines along joints
- Leaks at bar joints
Why it happens
Paint failure
Once the paint film breaks, water gets into the end grain and joints.
No maintenance
Timber needs redecorating on a cycle; skipped cycles turn small repairs into big ones.
About Dolgellau and the LL40 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
From Bangor, Gwynedd to Dolgellau is roughly 35 miles — all part of the Gwynedd area we cover.

How much should it cost?
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.
