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

Signs you need slipped glass panel repairs

  • 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?

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 Cornwall

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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

What should you expect to pay for slipped glass panel repairs in Cornwall?

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 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 Cornwall: 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 Cornwall do you cover?

All of Cornwall, including Truro, Redruth, Falmouth, St Austell, Camborne, Newquay. Rural and remote addresses are covered by arrangement.
