Pitched roof windows in Gorseinon: what is involved?
For Gorseinon homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Gorseinon, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
We work across West Glamorgan, including Gorseinon, and in neighbouring towns such as Llanelli and Swansea. 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
- Integral blinds and shutters
- Double or triple glazing
- Manual, electric or solar-powered opening
- Combination and stacked windows
- Flashings to suit tiles or slates
- Usually fitted in a day
Before you order: points to check
- Rafters may need trimming for wider windows
- Insulation collars and vapour control must be detailed
Planning, building control and Gorseinon
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. 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.

Common questions
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.
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.
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.
How do I book a survey in Gorseinon?
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 Gorseinon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
