What you might be seeing

  • A visible crack in the outer or inner pane
  • A starburst from an impact point
  • Broken glass inside the room — keep everyone out of the area

Why it happens

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.

Covering Porthcawl and nearby

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

From Bridgend to Porthcawl is roughly 6 miles — all part of the Mid Glamorgan area we cover.
