What do rooflight upstands & kerbs in Alfreton involve?
For Alfreton 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. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
From Alfreton to Ripley, Sutton in Ashfield and Kirkby in Ashfield, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Proprietary insulated kerbs
- Internal plaster-box linings
- Upstand repairs and rebuilds
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Timber upstands with insulation
- Fixings and falls agreed with the rooflight maker
- Built square to the rooflight size
What to check first
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
- Upstand size must match the unit within a tight tolerance
Planning, building control and Alfreton
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Questions about rooflight upstands & kerbs in Alfreton
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
How do I book a survey in Alfreton?
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 Alfreton?
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.
