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 from Gloucester (GL1) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Drips near the centre or top of the lantern
- A cracked or faded ridge end cap
- Staining along the hip bars inside
Common causes we find
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.
About Gloucester and the GL1 area
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.
If you're just outside Gloucester, we also cover Cheltenham (7 miles), Stroud (8 miles), Tewkesbury (9 miles).
Guide prices for ridge and hip repairs in Gloucester
Most ridge and hip repairs jobs come in between £195 and £445 ex VAT (£234–£534 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?
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.
