We carry out upstand and kerb repairs in Norwich and across the NR2 area. The upstand, or kerb, is the raised frame the lantern sits on.

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
Common causes we find
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.
Covering Norwich and nearby
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We also cover nearby Great Yarmouth (18 miles), Lowestoft (22 miles), Thetford (27 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.
