Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Belfast (BT1) 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
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.
About Belfast and the BT1 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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
We also cover nearby Newtownabbey (4 miles), Holywood (5 miles), Lisburn (7 miles).
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 Northern Ireland?
Most lantern repairs in Northern Ireland need no approval at all. Where a job turns into a replacement, the Building Regulations (Northern Ireland) 2012 apply and we confirm how the work will be signed off before we start. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
