Ridge and hip repairs in New Malden

In New Malden, as everywhere, 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 and we'll tell you what we think has failed.

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.

Roof lanterns in New Malden

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

How much should it cost?

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.

Faded or chalky caps are a sign of UV damage. Colour alone isn't a leak, but brittle caps crack, so we check them.
