What do rooflight upstands & kerbs in Ipswich involve?
For Ipswich homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
We cover all of Ipswich and the IP1 district, and nearby Harwich and Felixstowe.
Specification options
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Built square to the rooflight size
- Membrane dressed up and sealed
What to check first
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Membrane compatibility with the rooflight's sealants
Do you need permission in Ipswich?
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. 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.
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. 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.
Read the planning permission guide before you commit to a design.

What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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 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.

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.
