Rooflight upstands & kerbs for Gainsborough: the essentials
Rooflight upstands & kerbs in Gainsborough means insulated kerbs built and waterproofed to suit your rooflight. We cover the DN21 district and the rest of Lincolnshire, with a survey before any price is fixed.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
From Gainsborough to Retford, Scunthorpe and Lincoln, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Gainsborough
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.

Common questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Can you work alongside my builder in Gainsborough?
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 Gainsborough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
