Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Tonbridge (TN9) 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

Common causes we find
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.

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
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?
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.
