How we approach rooflight upstands & kerbs in Tunbridge Wells
For Tunbridge Wells 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Tunbridge Wells is around 23 km from Maidstone, and we survey and fit throughout that part of Kent, including the TN1 district.
What you can choose
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Internal plaster-box linings
- Proprietary insulated kerbs
- Raised upstands for deep green or ballasted roofs
- Upstand repairs and rebuilds
- Built square to the rooflight size
- Fixings and falls agreed with the rooflight maker
What to check first
- Membrane compatibility with the rooflight's sealants
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Do you need permission in Tunbridge Wells?
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.
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.

Rooflight upstands & kerbs in Tunbridge Wells: 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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Is the survey in Tunbridge Wells free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Tunbridge Wells?
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.
