In Tewkesbury, 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.

What you might be seeing
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
- Cold, damp or mouldy lining around the opening
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.
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.
Covering Tewkesbury and nearby
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

What should you expect to pay in Tewkesbury?
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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
