Signs you need upstand and kerb repairs

  • Water appearing below the lantern rather than from the glass
  • Soft or spongy timber at the base of the lantern
  • Roof membrane not lapped up the kerb, or peeling off it

What usually causes it?

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 Acton and the W3 area

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.

From Westminster to Acton is roughly 6 miles — all part of the Greater London area we cover.

How much should it cost?

Do you need permission in England?

In England, 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, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Upstand and kerb repairs in Acton: questions

Do you cover Acton?

Yes. We cover Acton, including the W3 postcode area, as part of Greater London. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.

Do you need to visit to price upstand and kerb repairs?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

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.
