Timber roof lanterns are beautiful and repairable, but they need sound paint, sound beads and dry timber. Send photos from Weymouth (DT4) 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
- Dark staining or black lines along joints
- Leaks at bar joints
Common causes we find
Paint failure
Once the paint film breaks, water gets into the end grain and joints.
Water trapped by beads
Glazing beads and putty can trap water against the timber if their seals fail.
Roof lanterns in Weymouth
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Weymouth is around 26 miles from Bournemouth, and both are within our Dorset coverage.

Guide prices for timber roof lantern repairs in Weymouth
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 England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

Timber roof lantern repairs in Weymouth: questions
How do I get a price for timber roof lantern repairs in Weymouth?
Send a few photos of the lantern and the problem, with your Weymouth postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
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.

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.
