Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Brentwood (CM14) 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
- Chalky or chipped powder coat
- Misted units
Common causes we find
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 Brentwood and nearby
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.

Guide prices for aluminium roof lantern repairs in Brentwood
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.
