Rooflight upstands & kerbs for Ashford, Surrey: the essentials
For Ashford, Surrey 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
We work across Surrey, including Ashford, Surrey, and in neighbouring towns such as Staines and Feltham. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Timber upstands with insulation
- Internal plaster-box linings
- Proprietary insulated kerbs

Before you order: points to check
- 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 Ashford, Surrey
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.

Questions about rooflight upstands & kerbs in Ashford, Surrey
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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Do I need to be at home for the survey in Ashford, Surrey?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
