Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos from Penzance (TR18) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Soft timber when pressed
- Putty or beads cracking and lifting
- Leaks at bar joints
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.
Roof lanterns in Penzance
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

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 England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
