We carry out flat rooflight and skylight repairs in Aberdare and across the CF44 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.

About Aberdare and the CF44 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.
From Bridgend to Aberdare is roughly 15 miles — all part of the Mid Glamorgan area we cover.
Close by, we also cover Rhondda (4 miles), Merthyr Tydfil (4 miles), Tonypandy (6 miles).
How much should it cost?
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including VAT), per rooflight. 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.
