Not the lantern
Sometimes the source is the flat roof, a parapet, a gutter or a wall above.
About Rhondda and the CF42 area
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.
Rhondda is around 12 miles from Bridgend, and both are within our Mid Glamorgan coverage.
We also cover nearby Tonypandy (3 miles), Aberdare (4 miles), Pontypridd (6 miles).
Guide prices for leak investigation and inspection in Rhondda
Typical range: £145–£295 ex VAT, which is £174–£354 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?
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.
