If the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos from Stornoway (HS1) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for solar control and self-cleaning glass upgrades?
- The room is noticeably hotter than the rest of the house in summer
- Glare on screens or worktops
- Clear, uncoated glass in an older lantern
Why it happens
Clear or standard Low-E glass
Standard units let a lot of solar heat through; solar control coatings reflect more of it.
No ventilation
A lantern without opening vents traps warm air at ceiling level.
About Stornoway and the HS1 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Stornoway 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.
How much should it cost?
Most solar control and self-cleaning glass upgrades jobs come in between £345 and £895 ex VAT (£414–£1,074 including 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.
