We carry out roof lantern leak repairs in Newport, Gwent and across the NP10 area. 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.

Is it time for roof lantern leak repairs?

  • Drips from a glazing bar or the eaves beam when it rains
  • Water running down the inside face of the glass
  • Damp patches on the ceiling a short distance from the lantern

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 Newport, Gwent

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Neighbouring places we cover include Risca (5 miles), Cwmbran (5 miles), Pontypool (8 miles).
