In Lancaster, as everywhere, 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 and we'll tell you what we think has failed.

Roof lantern glass panel slipped down past the eaves leaving a gap beneath the glazing bar

What you might be seeing

  • Glass edge overhanging the eaves more than its neighbours
  • A leak at the top of one pane only
  • A pane that looks out of line with the others

What usually causes it?

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.

Roof lanterns in Lancaster

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Guide price, per panel£195–£445 ex VAT£234–£534 inc VAT

Do you need permission in England?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Slipped glass panel repairs in Lancaster: questions

How do I get a price for slipped glass panel repairs in Lancaster?

Send a few photos of the lantern and the problem, with your Lancaster postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Can you repair a lantern someone else installed in Lancaster?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

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.
