Signs you need cracked lantern glass replacement

  • A visible crack in the outer or inner pane
  • A crack running from an edge (often thermal stress)

What usually causes it?

Impact

Hail, falling branches or dropped tools.

Spontaneous breakage

Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.

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.

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.
