Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos from Holyhead (LL65) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for cleaning and maintenance?
- Dirty glass or green algae on the frame
- You've never had it checked
- The lantern is under trees
Why it happens
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
Covering Holyhead and nearby
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Holyhead is around 21 miles from Bangor, Gwynedd, and both are within our Gwynedd coverage.
Neighbouring places we cover include Llangefni (14 miles), Caernarfon (19 miles), Bangor, Gwynedd (21 miles).
How much should it cost?
Typical range: £95–£245 ex VAT, which is £114–£294 with VAT, per visit. 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.
