What you might be seeing

  • Previous repairs haven't stopped the leak
  • The leak moves around or is intermittent
  • You need a written report for a landlord, insurer or builder

Why it happens

Hidden water paths

Water can travel along bars, decks and linings before it shows.

More than one fault

Older lanterns often have two or three small failures.

About Belfast and the BT1 area

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.

Neighbouring places we cover include Newtownabbey (4 miles), Holywood (5 miles), Lisburn (7 miles).
