Signs you need misted glass unit replacement

  • Fog, droplets or white bloom between the panes
  • One pane looks hazier than the others
  • Misting that comes and goes with the weather

Why it happens

Edge seal failure

Every sealed unit has an edge seal and desiccant. Once the seal fails, humid air gets in and the desiccant saturates.

Movement and age

Thermal movement and age wear the seal; units at the bottom of the lantern often go first.

Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.

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 Scotland?

In Scotland, 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 (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
