In Camborne, 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.

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
- Ponding water against the kerb after rain
Common causes we find
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.
About Camborne and the TR14 area
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 Camborne
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 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.
