The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Nelson (BB9) and we'll tell you which it is — with the price agreed in writing before any work.
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
- Ponding water against the kerb after rain
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.
About Nelson and the BB9 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
From Preston to Nelson is roughly 21 miles — all part of the Lancashire area we cover.
Close by, we also cover Colne (2 miles), Burnley (3 miles), Accrington (8 miles).
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.
