What do rooflight upstands & kerbs in Stratford involve?
Thinking about rooflight upstands & kerbs in Stratford? 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Jobs in Stratford 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
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Timber upstands with insulation
- Upstand repairs and rebuilds
- Built square to the rooflight size
- Membrane dressed up and sealed
Before you order: points to check
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Do you need permission in Stratford?
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. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Stratford
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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 do I book a survey in Stratford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Stratford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
