Rooflight upstands & kerbs in Acton: what is involved?
Rooflight upstands & kerbs in Acton means insulated kerbs built and waterproofed to suit your rooflight. We cover the W3 district and the rest of Greater London, with a survey before any price is fixed.
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. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
From Acton to Chiswick, Hammersmith and Shepherds Bush, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Acton
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Upstand repairs and rebuilds
- Membrane dressed up and sealed
- Built square to the rooflight size
Before you order: points to check
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Upstand size must match the unit within a tight tolerance
Planning, building control and Acton
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Rooflight upstands & kerbs in Acton: questions
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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 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.
Will I need planning permission in Acton?
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.
How do I book a survey in Acton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
