What do rooflight upstands & kerbs in Newtown involve?
For Newtown 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Newtown, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
We cover all of Newtown and the SY16 district, and nearby Welshpool and Llandrindod Wells.
Choices for your Newtown project
- Proprietary insulated kerbs
- Upstand repairs and rebuilds
- Raised upstands for deep green or ballasted roofs
- Timber upstands with insulation
- Internal plaster-box linings
- Insulated to avoid a cold bridge
- Correct height above the finished roof
What to check first
- Upstand size must match the unit within a tight tolerance
- Membrane compatibility with the rooflight's sealants
Planning and building rules for Newtown
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.
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.
Read the planning permission guide before you commit to a design.

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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
