Rooflight upstands & kerbs for Liverpool: the essentials
For Liverpool 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
We cover all of Liverpool and the L1 district, and nearby Birkenhead and Wallasey.
Specification options
- Proprietary insulated kerbs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Internal plaster-box linings
- Upstand repairs and rebuilds
- Correct height above the finished roof
- Insulated to avoid a cold bridge
Before you order: points to check
- Membrane compatibility with the rooflight's sealants
- Upstand size must match the unit within a tight tolerance
Do you need permission in Liverpool?
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
