We carry out upstand and kerb repairs in Grays and across the RM17 area. The upstand, or kerb, is the raised frame the lantern sits on.

Is it time for upstand and kerb repairs?
- Water appearing below the lantern rather than from the glass
- 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.
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 Grays
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
Grays is around 19 miles from Chelmsford, and both are within our Essex coverage.
If you're just outside Grays, we also cover South Ockendon (3 miles), Gravesend (3 miles), Dartford (5 miles).
How much should it cost?
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?
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.
