Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Forres (IV36) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Vent won't open or close
- Vent stops part-way or makes grinding noises

Why it happens
Actuator failure
Chain actuators wear out or jam, especially if they've been forced.
Power or control faults
Transformers, control units, switches and remotes fail; we check these first.
Roof lanterns in Forres
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
