In Bridgend, 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.

Signs you need cleaning and maintenance
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- The lantern is under trees
Common causes we find
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.
Covering Bridgend 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.
We also cover nearby Porthcawl (6 miles), Cowbridge (7 miles), Llantwit Major (8 miles).
How much should it cost?
Guide price for cleaning and maintenance: £95–£245 ex VAT (£114–£294 inc 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.
