We carry out ridge and hip repairs in Merthyr Tydfil and across the CF47 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
  • A cracked or faded ridge end cap
  • Sealant around the ridge cap split or missing

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 Merthyr Tydfil

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.

How much should it cost?

Guide price, per lantern£195–£445 ex VAT£234–£534 inc VAT

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.
