In Prestwick, 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
- Water appearing below the lantern rather than from the glass
- Roof membrane not lapped up the kerb, or peeling off it
- Cold, damp or mouldy lining around the opening
What usually causes it?
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
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.
Roof lanterns in Prestwick
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.

Guide prices for upstand and kerb repairs in Prestwick
Guide price for upstand and kerb repairs: £395–£1,295 ex VAT (£474–£1,554 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.
