Pitched roof windows for Dinas Powys: the essentials
We handle pitched roof windows across South Glamorgan, including Dinas Powys. In short: centre-pivot and top-hung skylights for tiled and slate roofs. 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. Typical uses for pitched roof windows include pitched roofs over bedrooms, stairs and bathrooms.
Neighbouring towns include Penarth (3 km) and Cardiff (6 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Dinas Powys
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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Pitched roof windows in Dinas Powys: questions
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 roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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 Dinas Powys?
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 Dinas Powys?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
