Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Cheadle Hulme (SK8) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need glazing bar and capping repairs
- A capping visibly higher than its neighbours
- Gasket rubber poking out, cracked or missing
- End caps missing at the bottom of a bar
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.
Covering Cheadle Hulme 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.
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.
From Manchester to Cheadle Hulme is roughly 8 miles — all part of the Greater Manchester area we cover.

How much should it cost?
Typical range: £165–£395 ex VAT, which is £198–£474 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.
