In Largs, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

Is it time for solar control and self-cleaning glass upgrades?

What usually causes it?
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
No ventilation
A lantern without opening vents traps warm air at ceiling level.
Roof lanterns in Largs
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
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.

How much should it cost?
Guide price for solar control and self-cleaning glass upgrades: £345–£895 ex VAT (£414–£1,074 inc VAT), per glass unit. 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.
