Covering Larne 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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

We cover Larne as part of County Antrim, about 18 miles from Belfast.

Do you need permission in Northern Ireland?

In Northern Ireland, 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 (Northern Ireland) 2012, so we set out the route in writing first. 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 Larne: questions

Can you repair a lantern someone else installed in Larne?

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.

Which places near Larne do you cover?

As well as Larne, we cover nearby Carrickfergus, Newtownabbey, Bangor, Down, Holywood and the rest of County Antrim.

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.

Will you tell me if repair is enough?

Yes. We'd rather do a repair that works than sell a lantern you don't need.
