How we approach rooflight upstands & kerbs in Pontypridd
Rooflight upstands & kerbs in Pontypridd means insulated kerbs built and waterproofed to suit your rooflight. We cover the CF37 district and the rest of Mid Glamorgan, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
We work across Mid Glamorgan, including Pontypridd, and in neighbouring towns such as Tonypandy and Caerphilly. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Pontypridd
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission. 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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. 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.

Common questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Do I need to be at home for the survey in Pontypridd?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
