We carry out roof lantern replacement in Dunoon and across the PA23 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.

Is it time for roof lantern replacement?
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
Common causes we find
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Roof lanterns in Dunoon
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 Oban to Dunoon is roughly 39 miles — all part of the Argyll and Bute area we cover.

How much should it cost?
Guide price for roof lantern replacement: £1,995–£4,995 ex VAT (£2,394–£5,994 inc VAT), supplied and fitted. 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 Scotland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.

Send a few photos of the lantern and the problem, with your Dunoon postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Can you repair a lantern someone else installed in Dunoon?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Can the new lantern use the existing opening?

Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
