What do rooflight upstands & kerbs in Cheshunt involve?
For Cheshunt 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 East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Waltham Abbey (2 km) and Enfield (7 km). We offer a survey date when we reply to your enquiry.

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

Questions about rooflight upstands & kerbs in Cheshunt
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
How do I book a survey in Cheshunt?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Cheshunt?
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.
