Bespoke & shaped rooflights for Cardiff: the essentials
We handle bespoke & shaped rooflights across South Glamorgan, including Cardiff. In short: triangular, angled, curved and multi-pane rooflights made to measure. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. In Cardiff, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
Cardiff is the main town we list in South Glamorgan; we also cover nearby Penarth and Dinas Powys.
What you can choose
- Solar-control and low-iron glass
- Triangular and trapezoid panes
- Concealed or slim frames
- Sloped or monopitch rooflights

- Drawing sign-off before order
Before you order: points to check
- Longer lead times and no returns on made-to-measure glass
- Precise survey and template may be needed
Consents for bespoke & shaped rooflights in Cardiff
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. 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.
