What do rooflight upstands & kerbs in Kettering involve?
For Kettering 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.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Kettering sits about 11 km from Wellingborough and 11 km from Corby, and we cover the whole NN16 postcode district and the roads in between.

Consents for rooflight upstands & kerbs in Kettering
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. 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.

Questions about rooflight upstands & kerbs in Kettering
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.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Will I need planning permission in Kettering?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
Can you work alongside my builder in Kettering?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
