Rooflight upstands & kerbs in Pontypool: what is involved?
Our rooflight upstands & kerbs service in Pontypool covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Pontypool is around 13 km from Newport, Gwent, and we survey and fit throughout that part of Gwent, including the NP4 district.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Proprietary insulated kerbs

- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds

Things we check at survey
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Membrane compatibility with the rooflight's sealants
Consents for rooflight upstands & kerbs in Pontypool
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.
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. 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.

Rooflight upstands & kerbs in Pontypool: questions
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
