Rooflight upstands & kerbs for Kingswood: the essentials
Rooflight upstands & kerbs in Kingswood means insulated kerbs built and waterproofed to suit your rooflight. We cover the BS15 district and the rest of Gloucestershire, with a survey before any price is fixed.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Kingswood is around 49 km from Gloucester, and we survey and fit throughout that part of Gloucestershire, including the BS15 district.

Do you need permission in Kingswood?
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. 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.

Common questions
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
How do I book a survey in Kingswood?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Kingswood?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
