Common causes we find

More than one fault

Older lanterns often have two or three small failures.

Not the lantern

Sometimes the source is the flat roof, a parapet, a gutter or a wall above.

Covering Carrickfergus 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.

Carrickfergus is around 10 miles from Belfast, and both are within our County Antrim coverage.

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.
