Structural damage

Impact or movement distorts the frame.

Covering Antrim and nearby

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.

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

Antrim is around 13 miles from Belfast, and both are within our County Antrim coverage.

Close by, we also cover Ballymena (12 miles), Newtownabbey (12 miles), Belfast (13 miles).

How much should it cost?

Guide price, supplied and fitted£1,995–£4,995 ex VAT£2,394–£5,994 inc VAT

Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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.

Roof lantern replacement in Antrim: questions

Do you need to visit to price roof lantern replacement?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you repair a lantern someone else installed in Antrim?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Standard sizes typically £1,995–£4,995 ex VAT supplied and fitted; bespoke sizes and kerb rebuilds are priced on survey. You get the fixed price in writing first.

Can the new lantern use the existing opening?

Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.
