We carry out timber roof lantern repairs in Penarth and across the CF64 area. Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber.

Is it time for timber roof lantern repairs?
- Soft timber when pressed
- 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 Penarth and the CF64 area
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 Penarth as part of South Glamorgan, about 3 miles from Cardiff.
Neighbouring places we cover include Cardiff (3 miles), Barry (5 miles), Caerphilly (10 miles).
What should you expect to pay in Penarth?
Typical range: £395–£1,995 ex VAT, which is £474–£2,394 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?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.

Timber roof lantern repairs in Penarth: questions
Do you cover Penarth?
Yes. We cover Penarth, including the CF64 postcode area, as part of South Glamorgan. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.
Do you need to visit to price timber roof lantern repairs?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Do you work on listed buildings?
Yes. Listed building consent may be needed for changes; like-for-like repair is generally treated differently from alteration, but check with your council's conservation officer before work.
How often does a timber lantern need painting?
It depends on exposure and paint system; many need redecorating every five to eight years.
