In Bolton, as everywhere, the ridge is where the hip bars and glazing bars meet at the top of a lantern, usually under a moulded or pressed end cap. Send photos and we'll tell you what we think has failed.

Signs you need ridge and hip repairs
- Drips near the centre or top of the lantern
- Sealant around the ridge cap split or missing
- Staining along the hip bars inside
Why it happens
Movement at the junction
Several bars meet at one point and each moves slightly with temperature; the seals at the ridge take the strain.
Poor original sealing
Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.
Roof lanterns in Bolton
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.
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.
Bolton is around 11 miles from Manchester, and both are within our Greater Manchester coverage.
We also cover nearby Farnworth (3 miles), Westhoughton (4 miles), Radcliffe (5 miles).
What should you expect to pay in Bolton?
Typical range: £195–£445 ex VAT, which is £234–£534 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
