What usually causes it?

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.

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.

What should you expect to pay for ridge and hip repairs in Greater London?

Guide price, per lantern£195–£445 ex VAT£234–£534 inc VAT

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?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.

Ridge and hip repairs in Greater London: questions

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.

Which towns in Greater London do you cover?

All of Greater London, including Westminster, Islington, Bexley, Barking, Archway, Sutton. Rural and remote addresses are covered by arrangement.
