Rooflight upstands & kerbs for Cromer: the essentials
We handle rooflight upstands & kerbs across Norfolk, including Cromer. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Jobs in Cromer 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.
Options we can specify in Cromer
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation

Things we check at survey
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Planning, building control and Cromer
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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Rooflight upstands & kerbs in Cromer: questions
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.
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Can you work alongside my builder in Cromer?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
