Is it time for upstand and kerb repairs?

  • Water appearing below the lantern rather than from the glass
  • Ponding water against the kerb after rain
  • 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.

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.

Covering Blackwood 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.

Blackwood is around 11 miles from Newport, Gwent, and both are within our Gwent coverage.

Upstand and kerb repairs in Blackwood: questions

How do I get a price for upstand and kerb repairs in Blackwood?

Send a few photos of the lantern and the problem, with your Blackwood postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Which places near Blackwood do you cover?

As well as Blackwood, we cover nearby Risca, Caerphilly, Pontypridd, Pontypool and the rest of Gwent.

Can you add insulation to the kerb?

Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.

Will my ceiling need repairing?

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.
