In Coatbridge, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Soft or spongy timber at the base of the lantern
- Roof membrane not lapped up the kerb, or peeling off it
- Cold, damp or mouldy lining around the opening
Why it happens
Membrane not dressed up
The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.
Rotten timber
Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.
Roof lanterns in Coatbridge
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.
From Hamilton to Coatbridge is roughly 7 miles — all part of the Lanarkshire area we cover.
Close by, we also cover Airdrie (2 miles), Bellshill (3 miles), Motherwell (5 miles).
How much should it cost?
Typical range: £395–£1,295 ex VAT, which is £474–£1,554 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 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.

Upstand and kerb repairs in Coatbridge: questions
Can you repair a lantern someone else installed in Coatbridge?
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.
Which places near Coatbridge do you cover?
As well as Coatbridge, we cover nearby Airdrie, Bellshill, Motherwell, Cumbernauld and the rest of Lanarkshire.
Can you add insulation to the kerb?
Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.
Will my ceiling need repairing?
If water has soaked the lining it may need making good after the leak is fixed; we can advise, but internal decorating isn't included unless quoted.
