Rooflight upstands & kerbs in Kilburn: what is involved?
For Kilburn 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
Kilburn is around 7 km from central London, and we survey and fit throughout that part of Greater London, including the NW6 district.

Planning, building control and Kilburn
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.

Questions about rooflight upstands & kerbs in Kilburn
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.
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 Kilburn?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
