We handle rooflight upstands & kerbs across Oxfordshire, including Witney. 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.

Do you need permission in Witney?
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.
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. 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 Witney
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
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.
Will I need planning permission in Witney?
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.
How do I book a survey in Witney?
