Rooflight upstands & kerbs in Basildon: what is involved?
Thinking about rooflight upstands & kerbs in Basildon? 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Jobs in Basildon 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.
Specification options
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Correct height above the finished roof
- Fixings and falls agreed with the rooflight maker
What to check first
- Membrane compatibility with the rooflight's sealants
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Consents for rooflight upstands & kerbs in Basildon
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. 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.
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 Basildon
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Is the survey in Basildon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Basildon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
