How we approach rooflight upstands & kerbs in Grays
Our rooflight upstands & kerbs service in Grays 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
From Grays to South Ockendon, Gravesend and Dartford, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Grays?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Common questions
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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 you work alongside my builder in Grays?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Grays?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
