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 from Nuneaton (CV11) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for roof lantern leak repairs?
- Brown staining or bubbling paint on the plasterboard lining around the lantern
- Water running down the inside face of the glass
- Damp patches on the ceiling a short distance from the lantern
Why it happens
Failed silicone or glazing tape
UV and thermal movement break down the seal between capping, gasket and glass. Once a gap opens, water tracks along the bar and drops at the lowest point.
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.
About Nuneaton and the CV11 area
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
From Warwick to Nuneaton is roughly 17 miles — all part of the Warwickshire area we cover.
We also cover nearby Bedworth (3 miles), Hinckley (4 miles), Coventry (8 miles).
How much should it cost?
Most roof lantern leak repairs jobs come in between £195 and £595 ex VAT (£234–£714 including 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?
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.
