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 Antrim (BT41) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for slipped glass panel repairs?
- A visible gap under the capping at the top of a pane
- Glass edge overhanging the eaves more than its neighbours
- A pane that looks out of line with the others
Why it happens
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
Covering Antrim and nearby
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.

Do you need permission in Northern Ireland?
In Northern Ireland, 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 Regulations (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
