Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Castle Douglas (DG7) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for aluminium roof lantern repairs?
- Leaks at bars or ridge
- Chalky or chipped powder coat
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Covering Castle Douglas and nearby
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.
Castle Douglas is around 15 miles from Dumfries, and both are within our Dumfries and Galloway coverage.

Guide prices for aluminium roof lantern repairs in Castle Douglas
Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 inc 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 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.
