Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Wolverhampton (WV1) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- A capping visibly higher than its neighbours
- Water running down one glazing bar inside
- Rattling or whistling in wind
Common causes we find
Gasket shrinkage
Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.
Fixings working loose
Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.
Roof lanterns in Wolverhampton
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
We cover Wolverhampton as part of West Midlands, about 12 miles from Birmingham.
We also cover nearby Wednesfield (2 miles), Willenhall (3 miles), Tipton (5 miles).
What should you expect to pay in Wolverhampton?
Guide price for glazing bar and capping repairs: £165–£395 ex VAT (£198–£474 inc 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.
