We carry out roof lantern leak repairs in Rugby and across the CV21 area. 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.

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
- A leak that only appears in wind-driven rain from one direction
Common causes we find
Blocked eaves drainage
Most lanterns collect water in a channel inside the eaves beam and let it out through weep slots. Leaves, moss and grit block the slots and the channel overflows indoors.
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 Rugby and the CV21 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.
Rugby is around 15 miles from Warwick, and both are within our Warwickshire coverage.
Neighbouring places we cover include Daventry (9 miles), Coventry (11 miles), Bedworth (11 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
