In Ossett, 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.

What you might be seeing
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
- Cold, damp or mouldy lining around the opening
Why it happens
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.
Covering Ossett and nearby
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
Ossett is around 8 miles from Leeds, and both are within our West Yorkshire coverage.
We also cover nearby Dewsbury (2 miles), Batley (3 miles), Wakefield (3 miles).
How much should it cost?
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?
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.
