Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Cardigan (SA43) 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
- Cappings lifted or rattling
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Roof lanterns in Cardigan
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
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.
