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 Ilkeston (DE7) 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
- Sealant around the ridge cap split or missing
What usually causes it?
UV-damaged end caps
Plastic ridge end caps become brittle and crack, especially on south-facing lanterns.
Poor original sealing
Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.
Roof lanterns in Ilkeston
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
Ilkeston is around 8 miles from Derby, and both are within our Derbyshire coverage.

How much should it cost?
Guide price for ridge and hip repairs: £195–£445 ex VAT (£234–£534 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?
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.
