In Truro, as everywhere, opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos and we'll tell you what we think has failed.

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

What you might be seeing

  • Vent won't open or close
  • Vent stops part-way or makes grinding noises
  • Leaks from around a closed vent

What usually causes it?

Power or control faults

Transformers, control units, switches and remotes fail; we check these first.

Seal or hinge problems

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

Covering Truro 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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

If you're just outside Truro, we also cover Falmouth (8 miles), Redruth (8 miles), Newquay (10 miles).

Guide prices for opening vent and actuator repairs in Truro

Do you need permission in England?

In England, 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 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
