Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Dungannon (BT70) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need opening vent and actuator repairs
- Vent won't open or close
- Vent stops part-way or makes grinding noises
- Rain sensor doesn't close the vent
Why it happens
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 Dungannon and nearby
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.
We cover Dungannon as part of County Tyrone, about 22 miles from Omagh.
Neighbouring places we cover include Cookstown (10 miles), Armagh (11 miles), Portadown (14 miles).
What should you expect to pay in Dungannon?
Typical range: £195–£545 ex VAT, which is £234–£654 with VAT, per vent. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Northern Ireland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. 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.
