Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Boston (PE21) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need aluminium roof lantern repairs
- Cappings lifted or rattling
- Chalky or chipped powder coat
- Corrosion at cut edges or fixings in coastal areas
What usually causes it?
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Roof lanterns in Boston
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

How much should it cost?
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?
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.
