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 Denbigh (LL16) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for ridge and hip repairs?
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
- Staining along the hip bars inside
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 Denbigh and the LL16 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.
Denbigh is around 20 miles from Wrexham, and both are within our Clwyd coverage.
Neighbouring places we cover include Ruthin (6 miles), Abergele (10 miles), Rhyl (10 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.
