We carry out upstand and kerb repairs in Hertford and across the SG13 area. The upstand, or kerb, is the raised frame the lantern sits on.

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
  • Ponding water against the kerb after rain

Common causes we find

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.

Rotten timber

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

Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

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.
