The upstand, or kerb, is the raised frame the lantern sits on. Send photos from Neath (SA11) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need upstand and kerb repairs
- Roof membrane not lapped up the kerb, or peeling off it
- Ponding water against the kerb after rain
- 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.
Rotten timber
Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.
About Neath and the SA11 area
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
From Swansea to Neath is roughly 7 miles — all part of the West Glamorgan area we cover.
If you're just outside Neath, we also cover Port Talbot (5 miles), Swansea (7 miles), Maesteg (7 miles).
Guide prices for upstand and kerb repairs in Neath
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 Wales?
In Wales, 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 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
