In Newtownabbey, 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.

What you might be seeing

- Leaks from around a closed vent
- Remote or switch unresponsive
What usually causes it?
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.
About Newtownabbey and the BT36 area
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.

Guide prices for opening vent and actuator repairs in Newtownabbey
Guide price for opening vent and actuator repairs: £195–£545 ex VAT (£234–£654 inc 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.
