We carry out ridge and hip repairs in Catford and across the SE6 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
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
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 Catford
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
From Westminster to Catford is roughly 6 miles — all part of the Greater London area we cover.
We also cover nearby Blackheath (2 miles), Greenwich (2 miles), Beckenham (3 miles).
How much should it cost?
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.

How do I get a price for ridge and hip repairs in Catford?
Send a few photos of the lantern and the problem, with your Catford postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
My ridge cap is a different colour from the frame — does that matter?
Faded or chalky caps are a sign of UV damage. Colour alone isn't a leak, but brittle caps crack, so we check them.
Can you replace just the ridge cap?
Yes, if a compatible cap is available and the seals underneath are sound.
