What do rooflight upstands & kerbs in Redland involve?
For Redland 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 South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Jobs in Redland 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 Redland
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Upstand repairs and rebuilds
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Proprietary insulated kerbs

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
Planning and building rules for Redland
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. 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.
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. 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.
Read the planning permission guide before you commit to a design.

Rooflight upstands & kerbs in Redland: questions
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.
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
