Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Falmouth (TR11) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need aluminium roof lantern repairs
- Leaks at bars or ridge
- Cappings lifted or rattling
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
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.
About Falmouth and the TR11 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
From Truro to Falmouth is roughly 8 miles — all part of the Cornwall area we cover.

How much should it cost?
Most aluminium roof lantern repairs jobs come in between £195 and £695 ex VAT (£234–£834 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.
