How we approach rooflight upstands & kerbs in Leigh
For Leigh 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Neighbouring towns include Atherton (3 km) and Tyldesley (4 km). We offer a survey date when we reply to your enquiry.

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 Leigh
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

More we do in Leigh
Rooflight upstands & kerbs in Leigh: questions
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 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.
Do I need to be at home for the survey in Leigh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Leigh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
