Rooflight upstands & kerbs for Bracknell: the essentials
For Bracknell 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Bracknell is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG12 district.
Specification options
- Upstand repairs and rebuilds
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Correct height above the finished roof
- Insulated to avoid a cold bridge
Things we check at survey
- Upstand size must match the unit within a tight tolerance
- Membrane compatibility with the rooflight's sealants
Do you need permission in Bracknell?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Common questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Is the survey in Bracknell free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Bracknell?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
