Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Deal (CT14) 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

What usually causes it?
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Covering Deal 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.
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?
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?
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.
