How we approach rooflight upstands & kerbs in New Malden
Thinking about rooflight upstands & kerbs in New Malden? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we 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. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.
Neighbouring towns include Surbiton (3 km) and Kingston upon Thames (4 km). We offer a survey date when we reply to your enquiry.

Do you need permission in New Malden?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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 New Malden
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Is the survey in New Malden free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in New Malden?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
