Rooflight upstands & kerbs for Winsford: the essentials
Rooflight upstands & kerbs in Winsford means insulated kerbs built and waterproofed to suit your rooflight. We cover the CW7 district and the rest of Cheshire, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
From Winsford to Northwich, Crewe and Congleton, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Winsford
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.
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.

Rooflight upstands & kerbs in Winsford: questions
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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 you work alongside my builder in Winsford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Winsford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
