What do rooflight upstands & kerbs in Crowborough involve?
For Crowborough 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
We work across East Sussex, including Crowborough, and in neighbouring towns such as Tunbridge Wells and East Grinstead. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Raised upstands for deep green or ballasted roofs
- Proprietary insulated kerbs
- Upstand repairs and rebuilds
- Timber upstands with insulation
- Built square to the rooflight size
- Matched to your roof covering
Before you order: points to check
- Insulation continuity around the upstand affects condensation
- Upstand size must match the unit within a tight tolerance
Do you need permission in Crowborough?
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Do I need to be at home for the survey in Crowborough?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
