In Tredegar, as everywhere, if a roof lantern pane looks cloudy or wet between the two layers of glass, the sealed unit has failed and moisture has got inside. Send photos and we'll tell you what we think has failed.

Roof lantern seen from inside with one misted double glazed pane between clear panes

What you might be seeing

  • One pane looks hazier than the others
  • Misting that comes and goes with the weather
  • Water marks or tide lines inside the unit

Common causes we find

Water sitting on the edge

If the unit's edge sits in water because the eaves don't drain, the seal fails sooner.

Movement and age

Thermal movement and age wear the seal; units at the bottom of the lantern often go first.

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Do you need permission in Wales?

Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

We match tint and coatings as closely as possible; a new unit can look very slightly clearer than older neighbours.
