We carry out upstand and kerb repairs in Liverpool and across the L1 area. The upstand, or kerb, is the raised frame the lantern sits on.

What you might be seeing
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
What usually causes it?
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.
Roof lanterns in Liverpool
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.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
If you're just outside Liverpool, we also cover Birkenhead (2 miles), Wallasey (4 miles), Litherland (4 miles).
What should you expect to pay in Liverpool?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
