A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Grangemouth (FK3) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
- Broken glass inside the room — keep everyone out of the area
Common causes we find
Thermal stress
Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.
