How we approach rooflight upstands & kerbs in Hammersmith
Our rooflight upstands & kerbs service in Hammersmith covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Shepherds Bush (1 km) and Chiswick (2 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Hammersmith
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.
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.

Questions about rooflight upstands & kerbs in Hammersmith
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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
