What do pitched roof windows in Merthyr Tydfil involve?
Our pitched roof windows service in Merthyr Tydfil covers centre-pivot and top-hung skylights for tiled and slate roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Merthyr Tydfil, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
We work across Mid Glamorgan, including Merthyr Tydfil, and in neighbouring towns such as Aberdare and Rhondda. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Merthyr Tydfil
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Pitched roof windows in Merthyr Tydfil: questions
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
