Rooflight upstands & kerbs in Llanelli: what is involved?
For Llanelli homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Llanelli is the main town we list in Dyfed; we also cover nearby Gorseinon and Swansea.
Specification options
- Proprietary insulated kerbs
- Upstand repairs and rebuilds
- Raised upstands for deep green or ballasted roofs
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Matched to your roof covering
- Correct height above the finished roof
Things we check at survey
- Insulation continuity around the upstand affects condensation
- Membrane compatibility with the rooflight's sealants
Do you need permission in Llanelli?
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. 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.

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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
