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
  • Ponding water against the kerb after rain

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 Beckenham 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.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

From Westminster to Beckenham is roughly 8 miles — all part of the Greater London area we cover.

We also cover nearby Catford (3 miles), Croydon (4 miles), Blackheath (4 miles).

How much should it cost?

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?

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.
