We carry out roof lantern leak repairs in Hatfield and across the AL10 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?
- Drips from a glazing bar or the eaves beam when it rains
- Water running down the inside face of the glass
- Damp patches on the ceiling a short distance from the lantern
What usually causes it?
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.
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.
Covering Hatfield and nearby
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.
Hatfield is around 5 miles from St Albans, and both are within our Hertfordshire coverage.

Guide prices for roof lantern leak repairs in Hatfield
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?
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.
