In Chelmsford, as everywhere, a roof lantern leak is almost always a failed seal, a lifted capping, blocked eaves drainage or a problem where the kerb meets the flat roof — not a failed lantern. Send photos and we'll tell you what we think has failed.

Signs you need roof lantern leak repairs

  • Brown staining or bubbling paint on the plasterboard lining around the lantern
  • Damp patches on the ceiling a short distance from the lantern
  • A leak that only appears in wind-driven rain from one direction

Common causes we find

Lifted or misaligned cappings

Top cappings clip or screw over each glazing bar. If one has lifted, been knocked or was never seated, rain gets straight under it.

The kerb or roof junction

If the flat roof membrane isn't dressed high enough up the kerb, or the kerb has no fall, water sits against the joint and finds its way in under the lantern.

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

Close by, we also cover Billericay (8 miles), Witham (9 miles), Maldon (9 miles).

How much should it cost?

Guide price, per lantern£195–£595 ex VAT£234–£714 inc VAT

Guide price for roof lantern leak repairs: £195–£595 ex VAT (£234–£714 inc VAT), per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.

Do you need permission in England?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
