Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Holyhead (LL65) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Misted glass
- 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.
About Holyhead and the LL65 area
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.
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.

Guide prices for flat rooflight and skylight repairs in Holyhead
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including VAT), per rooflight. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Wales?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.
