Rooflight upstands & kerbs in Canvey Island: what is involved?
We handle rooflight upstands & kerbs across Essex, including Canvey Island. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Canvey Island is around 9 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the SS8 district.

Do you need permission in Canvey Island?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.

Rooflight upstands & kerbs in Canvey Island: questions
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.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can you work alongside my builder in Canvey Island?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Canvey Island?
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.
