We carry out ridge and hip repairs in St Austell and across the PL25 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
  • Sealant around the ridge cap split or missing
  • Staining along the hip bars inside

Why it happens

UV-damaged end caps

Plastic ridge end caps become brittle and crack, especially on south-facing lanterns.

Poor original sealing

Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.

Roof lanterns in St Austell

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

St Austell is around 13 miles from Truro, and both are within our Cornwall coverage.

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.

Ridge and hip repairs in St Austell: 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.

Can you repair a lantern someone else installed in St Austell?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

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.
