Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Bath (BA1) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for aluminium roof lantern repairs?
- Leaks at bars or ridge
- Misted units
- Corrosion at cut edges or fixings in coastal areas
Why it happens
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
About Bath and the BA1 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Close by, we also cover Trowbridge (8 miles), Frome (10 miles), Bristol (12 miles).
How much should it cost?
Typical range: £195–£695 ex VAT, which is £234–£834 with 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.
