Rooflight upstands & kerbs for Chapeltown: the essentials
Thinking about rooflight upstands & kerbs in Chapeltown? 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.
Converted barns and mills in Yorkshire often suit bespoke or ridge rooflights that follow the original structure. In Chapeltown, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Chapeltown is around 9 km from Sheffield, and we survey and fit throughout that part of South Yorkshire, including the S35 district.

- Upstands to suit single-ply, felt, GRP or liquid roofs
- Raised upstands for deep green or ballasted roofs
- Upstand repairs and rebuilds
- Internal plaster-box linings
- Proprietary insulated kerbs
- Fixings and falls agreed with the rooflight maker
- Built square to the rooflight size
What to check first
- Upstand size must match the unit within a tight tolerance
- Insulation continuity around the upstand affects condensation
Planning and building rules for Chapeltown
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.

Rooflight upstands & kerbs in Chapeltown: questions
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.
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.
