What you might be seeing

  • Previous repairs haven't stopped the leak
  • The leak moves around or is intermittent
  • You're not sure if it's a leak or condensation

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.

Roof lanterns in Antrim

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.

From Belfast to Antrim is roughly 13 miles — all part of the County Antrim area we cover.

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.
