In Berkhamsted, 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.

Signs you need ridge and hip repairs

  • 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.

Covering Berkhamsted and nearby

Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.

From St Albans to Berkhamsted is roughly 10 miles — all part of the Hertfordshire area we cover.

Neighbouring places we cover include Chesham (4 miles), Hemel Hempstead (5 miles), Amersham (7 miles).

What should you expect to pay in Berkhamsted?

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?

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.

Ridge and hip repairs in Berkhamsted: questions

What does a ridge repair cost?

Usually £195–£445 ex VAT for a standard lantern, confirmed in writing before work starts.

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.
