The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Corby (NN17) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for upstand and kerb repairs?
- 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
Why it happens
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
Rotten timber
Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.
Covering Corby and nearby
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

How much should it cost?
Most upstand and kerb repairs jobs come in between £395 and £1,295 ex VAT (£474–£1,554 including 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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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.
