What do rooflight upstands & kerbs in Putney involve?
Thinking about rooflight upstands & kerbs in Putney? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Putney, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
Jobs in Putney are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Putney project
- Raised upstands for deep green or ballasted roofs
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Proprietary insulated kerbs
- Fixings and falls agreed with the rooflight maker
- Insulated to avoid a cold bridge
Things we check at survey
- Upstand size must match the unit within a tight tolerance
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Consents for rooflight upstands & kerbs in Putney
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.
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.

Questions about rooflight upstands & kerbs in Putney
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Will I need planning permission in Putney?
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 Putney?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
