The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Daventry (NN11) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need upstand and kerb repairs
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Cold, damp or mouldy lining around the opening
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 Daventry
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.

Guide prices for upstand and kerb repairs in Daventry
Typical range: £395–£1,295 ex VAT, which is £474–£1,554 with 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.
