What do rooflight upstands & kerbs in Port Talbot involve?
We handle rooflight upstands & kerbs across West Glamorgan, including Port Talbot. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
Port Talbot sits about 5 km from Briton Ferry and 8 km from Neath, and we cover the whole SA12 postcode district and the roads in between.
What you can choose
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Upstand repairs and rebuilds
- Fixings and falls agreed with the rooflight maker
- Membrane dressed up and sealed
Things we check at survey
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Planning, building control and Port Talbot
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.
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.

Common questions
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
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.
How do I book a survey in Port Talbot?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Port Talbot?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
