In Swansea, as everywhere, the upstand, or kerb, is the raised frame the lantern sits on. Send photos and we'll tell you what we think has failed.

Roofer dressing EPDM membrane up the timber kerb under a roof lantern

What you might be seeing

  • Water appearing below the lantern rather than from the glass
  • Roof membrane not lapped up the kerb, or peeling off it
  • Cold, damp or mouldy lining around the opening

Common causes we find

Kerb too low

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

Membrane not dressed up

The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.

About Swansea and the SA1 area

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Close by, we also cover Gorseinon (5 miles), Neath (7 miles), Port Talbot (7 miles).

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.

Can you add insulation to the kerb?

If water has soaked the lining it may need making good after the leak is fixed; we can advise, but internal decorating isn't included unless quoted.
