We carry out upstand and kerb repairs in Canterbury and across the CT1 area. The upstand, or kerb, is the raised frame the lantern sits on.

Signs you need upstand and kerb repairs

  • Water appearing below the lantern rather than from the glass
  • Roof membrane not lapped up the kerb, or peeling off it
  • 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.

Roof lanterns in Canterbury

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

We cover Canterbury as part of Kent, about 24 miles from Maidstone.

How much should it cost?

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

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?

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.
