In Lockerbie, as everywhere, flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos and we'll tell you what we think has failed.

Is it time for flat rooflight and skylight repairs?
- Misted glass
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
Why it happens
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Unit failure
Edge seals fail and the unit mists.
Covering Lockerbie and nearby
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.
Lockerbie is around 11 miles from Dumfries, and both are within our Dumfries and Galloway coverage.
We also cover nearby Annan (10 miles), Dumfries (11 miles), Castle Douglas (26 miles).
How much should it cost?
Guide price for flat rooflight and skylight repairs: £195–£595 ex VAT (£234–£714 inc VAT), per rooflight. 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.
