Rooflight upstands & kerbs in Uxbridge: what is involved?
Rooflight upstands & kerbs in Uxbridge means insulated kerbs built and waterproofed to suit your rooflight. We cover the UB8 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Jobs in Uxbridge are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Raised upstands for deep green or ballasted roofs
- Proprietary insulated kerbs

Things we check at survey
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Insulation continuity around the upstand affects condensation
Planning and building rules for Uxbridge
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
