Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Harwich (CO12) 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
- Chalky or chipped powder coat
- Corrosion at cut edges or fixings in coastal areas
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 Harwich and nearby
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
From Chelmsford to Harwich is roughly 38 miles — all part of the Essex area we cover.

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?
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.
