We carry out aluminium roof lantern repairs in Sandown and across the PO36 area. Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear.

What you might be seeing
- Leaks at bars or ridge
- Chalky or chipped powder coat
- Misted units
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 Sandown
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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 cover Sandown by arrangement: island work is planned around ferry access, and any travel or access costs are set out in your written quote before you commit.
If you're just outside Sandown, we also cover Ryde (5 miles), Newport, Isle of Wight (7 miles), Cowes (10 miles).
How much should it cost?
Typical range: £195–£695 ex VAT, which is £234–£834 with 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.
