How we approach rooflight upstands & kerbs in Prestwich
Rooflight upstands & kerbs in Prestwich means insulated kerbs built and waterproofed to suit your rooflight. We cover the M25 district and the rest of Greater Manchester, with a survey before any price is fixed.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Prestwich, as anywhere, rooflight upstands & kerbs are the usual choice for roofs where the old kerb is low, cold or leaking.
Neighbouring towns include Whitefield (2 km) and Radcliffe (4 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Prestwich?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Rooflight upstands & kerbs in Prestwich: questions
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 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.
Do I need to be at home for the survey in Prestwich?
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 Prestwich?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
