Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Gainsborough (DN21) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Leaks at bars or ridge
- Chalky or chipped powder coat
- Misted units
What usually causes it?
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.
Covering Gainsborough and nearby
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Guide prices for aluminium roof lantern repairs in Gainsborough
Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 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.
