In Lanark, as everywhere, a roof lantern leak is almost always a failed seal, a lifted capping, blocked eaves drainage or a problem where the kerb meets the flat roof — not a failed lantern. Send photos and we'll tell you what we think has failed.

Rainwater running down an internal glazing bar of a roof lantern above a kitchen

What you might be seeing

  • Drips from a glazing bar or the eaves beam when it rains
  • Damp patches on the ceiling a short distance from the lantern
  • A leak that only appears in wind-driven rain from one direction

Common causes we find

Failed silicone or glazing tape

UV and thermal movement break down the seal between capping, gasket and glass. Once a gap opens, water tracks along the bar and drops at the lowest point.

The kerb or roof junction

If the flat roof membrane isn't dressed high enough up the kerb, or the kerb has no fall, water sits against the joint and finds its way in under the lantern.

Roof lanterns in Lanark

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.
