Rooflight upstands & kerbs for Gloucester: the essentials
We handle rooflight upstands & kerbs across Gloucestershire, including Gloucester. 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
We cover all of Gloucester and the GL1 district, and nearby Cheltenham and Stroud.

Do you need permission in Gloucester?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Rooflight upstands & kerbs in Gloucester: 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.
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.
Will I need planning permission in Gloucester?
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.
Can you work alongside my builder in Gloucester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
