- Sealant around the ridge cap split or missing

What usually causes it?
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.
Covering Porthcawl and nearby
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.

Do you need permission in Wales?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.
