A slipped panel is a glass unit that has slid down its glazing bars, leaving a gap at the top and often pushing past the eaves at the bottom. Send photos from Dundee (DD1) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- A visible gap under the capping at the top of a pane
- Glass edge overhanging the eaves more than its neighbours
- A leak at the top of one pane only
Common causes we find
Missing setting blocks
Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
Roof lanterns in Dundee
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Neighbouring places we cover include Carnoustie (10 miles), Cupar (10 miles), St Andrews (11 miles).
How much should it cost?
Guide price for slipped glass panel repairs: £195–£445 ex VAT (£234–£534 inc VAT), per panel. 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. 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.
