A cracked pane in a roof lantern needs prompt attention because the glass is overhead. We carry out cracked lantern glass replacement across Powys, with a guide price from your photos and a fixed price in writing before any work starts.
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)
- Broken glass inside the room — keep everyone out of the area
What usually causes it?
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.
Roof lanterns in Powys
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.

Do you need permission in Wales?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.
