Ridge & pitched glass roofs in Dinas Powys: what is involved?
We handle ridge & pitched glass roofs across South Glamorgan, including Dinas Powys. In short: dual-pitch glazed roofs for side returns, links and long extensions. 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. Think of ridge & pitched glass roofs for side returns, links and long extensions.
Dinas Powys is around 6 km from Cardiff, and we survey and fit throughout that part of South Glamorgan, including the CF64 district.
What you can choose
- Dual-pitch or mono-pitch
- Aluminium systems in standard and RAL colours
- Opening vents and electric actuators
- Integrated gutters and box gutters
- Fixed or retractable shading
- Slim aluminium glazing bars
- Works with exposed brick and period detail
Before you order: points to check
- Large glass roofs affect the energy calculation for the extension
- Party-wall agreements may apply on terraced houses
Do you need permission in Dinas Powys?
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.
