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 Barnet (EN5) and we'll tell you which it is — with the price agreed in writing before any work.

Ridge end cap and hip bars at the top of an anthracite aluminium roof lantern

What you might be seeing

  • A cracked or faded ridge end cap
  • Sealant around the ridge cap split or missing
  • Staining along the hip bars inside

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.

Covering Barnet and nearby

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.

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.

Barnet is around 11 miles from Westminster, and both are within our Greater London coverage.

Close by, we also cover Potters Bar (3 miles), Borehamwood (3 miles), Finchley (3 miles).

What should you expect to pay in Barnet?

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

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?

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 Barnet: questions

Do you need to visit to price ridge and hip repairs?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Which places near Barnet do you cover?

As well as Barnet, we cover nearby Potters Bar, Borehamwood, Finchley, Muswell Hill and the rest of Greater London.

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.
