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. We carry out slipped glass panel repairs across County Tyrone, with a guide price from your photos and a fixed price in writing before any work starts.

Signs you need 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
What usually causes it?
Missing setting blocks
Blocks under the bottom edge carry the weight of the unit; if they're missing or crushed, the unit creeps down.
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.
Roof lanterns in County Tyrone
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.
What should you expect to pay for slipped glass panel repairs in County Tyrone?
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 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.

Slipped glass panel repairs in County Tyrone: questions
Can a slipped panel be pushed back up?
Not safely without removing the capping. The fix is to support the unit properly so it can't slip again.
Does a slipped panel mean my lantern was badly fitted?
Not necessarily — blocks can crush and stops can break over time — but if the lantern is new, talk to the installer first as it may be under warranty.
Which towns in County Tyrone do you cover?
