Is it time for upstand and kerb repairs?

  • 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

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.

Roof lanterns in Blackheath

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

From Westminster to Blackheath is roughly 7 miles — all part of the Greater London area we cover.

What should you expect to pay in Blackheath?

Guide price, per lantern£395–£1,295 ex VAT£474–£1,554 inc VAT

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.
