Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Perth (PH1) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Leaks at bars or ridge
- Cappings lifted or rattling
- Misted units
Why it happens
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.
Roof lanterns in Perth
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
We also cover nearby Auchterarder (13 miles), Kinross (13 miles), Blairgowrie (14 miles).
What should you expect to pay in Perth?
Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 inc 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 Scotland?
In Scotland, 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 (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
