Roofer dressing EPDM membrane up the timber kerb under a roof lantern

What you might be seeing

  • 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

What usually causes it?

Kerb too low

If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.

Rotten timber

Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.

Covering Chesham and nearby

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

From Aylesbury to Chesham is roughly 12 miles — all part of the Buckinghamshire area we cover.

Close by, we also cover Amersham (2 miles), Berkhamsted (4 miles), Chalfont St Peter (7 miles).

Guide prices for upstand and kerb repairs in Chesham

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.
