In Magherafelt, 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
  • Leaks from around a closed vent
  • Rain sensor doesn't close the vent

Common causes we find

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.

Roof lanterns in Magherafelt

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Magherafelt is around 33 miles from Derry~Londonderry, and both are within our County Londonderry coverage.

Close by, we also cover Cookstown (9 miles), Ballymena (15 miles), Antrim (17 miles).

How much should it cost?

Guide price, per vent£195–£545 ex VAT£234–£654 inc VAT

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.
