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 Cardigan (SA43) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Drips near the centre or top of the lantern
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
Common causes we find
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.
About Cardigan and the SA43 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Cardigan is around 22 miles from Carmarthen, and both are within our Dyfed coverage.
Close by, we also cover Carmarthen (22 miles), Haverfordwest (23 miles), Pembroke Dock (30 miles).
How much should it cost?
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?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.

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