Is it time for opening vent and actuator repairs?

  • Vent stops part-way or makes grinding noises
  • Leaks from around a closed vent

Why it happens

Actuator failure

Chain actuators wear out or jam, especially if they've been forced.

Seal or hinge problems

A twisted hinge or worn seal stops the vent closing tight.

Covering Portstewart 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.

Do you need permission in Northern Ireland?

In Northern Ireland, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations (Northern Ireland) 2012, so we set out the route in writing first. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.
