In Weymouth, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

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

Is it time for upstand and kerb repairs?

  • Soft or spongy timber at the base of the lantern
  • Roof membrane not lapped up the kerb, or peeling off it
  • Cold, damp or mouldy lining around the opening

Common causes we find

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 Weymouth

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.

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

Weymouth is around 26 miles from Bournemouth, and both are within our Dorset coverage.

If you're just outside Weymouth, we also cover Poole (22 miles), Yeovil (24 miles), Bournemouth (26 miles).

Guide prices for upstand and kerb repairs in Weymouth

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.
