In Aberystwyth, as everywhere, most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos and we'll tell you what we think has failed.

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
Common causes we find
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
Roof lanterns in Aberystwyth
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
From Carmarthen to Aberystwyth is roughly 40 miles — all part of the Dyfed area we cover.

What should you expect to pay in Aberystwyth?
Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 including 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. 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.
