How we approach pitched roof windows in Cowbridge
Our pitched roof windows service in Cowbridge 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.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
We work across South Glamorgan, including Cowbridge, and in neighbouring towns such as Llantwit Major and Bridgend. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Flashings for tiles, slates or recessed fitting
- Manual, electric or solar-powered opening
- Double or triple glazing
- Combination and stacked windows
- Centre-pivot or top-hung
- Blinds and electric opening available
- Fits between rafters in most roofs
Before you order: points to check
- Front-facing roof windows can need permission in conservation areas
- Escape-window rules can apply to loft rooms
Planning and building rules for Cowbridge
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about pitched roof windows in Cowbridge
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
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.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
How do I book a survey in Cowbridge?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Cowbridge?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
