A roof lantern leak is almost always a failed seal, a lifted capping, blocked eaves drainage or a problem where the kerb meets the flat roof — not a failed lantern. Send photos from Craigavon (BT62) and we'll tell you which it is — with the price agreed in writing before any work.
Is it time for roof lantern leak repairs?
- Drips from a glazing bar or the eaves beam when it rains
- Brown staining or bubbling paint on the plasterboard lining around the lantern
- Water running down the inside face of the glass
Common causes we find
Failed silicone or glazing tape
UV and thermal movement break down the seal between capping, gasket and glass. Once a gap opens, water tracks along the bar and drops at the lowest point.
The kerb or roof junction
If the flat roof membrane isn't dressed high enough up the kerb, or the kerb has no fall, water sits against the joint and finds its way in under the lantern.
Roof lanterns in Craigavon
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.

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.
