We carry out ridge and hip repairs in Redhill and across the RH1 area. 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.

What you might be seeing
- 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
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 Redhill
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Redhill is around 17 miles from Guildford, and both are within our Surrey coverage.
Neighbouring places we cover include Reigate (2 miles), Horley (5 miles), Caterham (5 miles).
How much should it cost?
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.
