We carry out ridge and hip repairs in Penarth and across the CF64 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.

Signs you need ridge and hip repairs

  • Drips near the centre or top of the lantern
  • A cracked or faded ridge end cap
  • Staining along the hip bars inside

Common causes we find

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.

About Penarth and the CF64 area

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

We cover Penarth as part of South Glamorgan, about 3 miles from Cardiff.

We also cover nearby Cardiff (3 miles), Barry (5 miles), Caerphilly (10 miles).

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 Wales?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

Ridge and hip repairs in Penarth: 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 Penarth do you cover?

As well as Penarth, we cover nearby Cardiff, Barry, Caerphilly, Cowbridge and the rest of South Glamorgan.

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.
