In Ruthin, as everywhere, flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos and we'll tell you what we think has failed.

Is it time for flat rooflight and skylight repairs?
- Water around the rooflight edge
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
What usually causes it?
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
Covering Ruthin and nearby
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 Wales?
Most lantern repairs in Wales need no approval at all. 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.
