What do rooflight upstands & kerbs in Edmonton involve?
For Edmonton 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Edmonton is around 14 km from central London, and we survey and fit throughout that part of Greater London, including the N18 district.
Specification options
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Upstand repairs and rebuilds

Things we check at survey
- Insulation continuity around the upstand affects condensation
- Membrane compatibility with the rooflight's sealants
Planning and building rules for Edmonton
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Rooflight upstands & kerbs in Edmonton: questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Is the survey in Edmonton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
