About Aberdare and the CF44 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.
We cover Aberdare as part of Mid Glamorgan, about 15 miles from Bridgend.
Close by, we also cover Rhondda (4 miles), Merthyr Tydfil (4 miles), Tonypandy (6 miles).
Guide prices for roof lantern replacement in Aberdare
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including VAT), supplied and fitted. 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.
