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.

Loose cappings

If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.

Roof lanterns in Dyfed

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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Do you need permission in Wales?

In Wales, 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 2010 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

Slipped glass panel repairs in Dyfed: 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 Dyfed do you cover?

All of Dyfed, including Carmarthen, Llanelli, Ammanford, Aberystwyth, Cardigan, Haverfordwest. Rural and remote addresses are covered by arrangement.
