Open electric vent in a roof lantern with chain actuator visible from inside

What you might be seeing

  • Vent stops part-way or makes grinding noises
  • Rain sensor doesn't close the vent

Common causes we find

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 Bangor, Gwynedd

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Neighbouring places we cover include Llangefni (8 miles), Caernarfon (8 miles), Llandudno (14 miles).
