What you might be seeing

  • Water appearing below the lantern rather than from the glass
  • Soft or spongy timber at the base of the lantern
  • Cold, damp or mouldy lining around the opening

Why it happens

Kerb too low

If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.

Rotten timber

Untreated or wet timber kerbs rot from inside, so the lantern loses support and the seals open.

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.
