Rooflight upstands & kerbs in Holyhead: what is involved?
Our rooflight upstands & kerbs service in Holyhead 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
We work across Gwynedd, including Holyhead, and in neighbouring towns such as Llangefni and Caernarfon. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Holyhead
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs

Before you order: points to check
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Upstand size must match the unit within a tight tolerance
Planning and building rules for Holyhead
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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Rooflight upstands & kerbs in Holyhead: questions
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can you work alongside my builder in Holyhead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Holyhead?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
