Rooflight upstands & kerbs for Hull: the essentials
For Hull 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.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Hull is the main town we list in the East Riding of Yorkshire; we also cover nearby Beverley and Hornsea.
What you can choose
- Upstand repairs and rebuilds
- Timber upstands with insulation
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Raised upstands for deep green or ballasted roofs
- Matched to your roof covering
- Correct height above the finished roof
Things we check at survey
- Insulation continuity around the upstand affects condensation
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Consents for rooflight upstands & kerbs in Hull
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. 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 Hull
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Is the survey in Hull free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Hull?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
