Rooflight upstands & kerbs for Leyland: the essentials
For Leyland 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
Leyland is around 7 km from Preston, and we survey and fit throughout that part of Lancashire, including the PR25 district.
What you can choose
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Upstand repairs and rebuilds
- Fixings and falls agreed with the rooflight maker
- Correct height above the finished roof
Things we check at survey
- Membrane compatibility with the rooflight's sealants
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Planning and building rules for Leyland
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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 Leyland: questions
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
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.
Can you work alongside my builder in Leyland?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Leyland?
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.
