Rooflight upstands & kerbs in South Benfleet: what is involved?
For South Benfleet 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.
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 roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Pitsea (4 km) and Canvey Island (4 km). We offer a survey date when we reply to your enquiry.

Do you need permission in South Benfleet?
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. 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.
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. 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.

Rooflight upstands & kerbs in South Benfleet: questions
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.
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.
How do I book a survey in South Benfleet?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in South Benfleet free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
