Rooflight upstands & kerbs in Chesterfield: what is involved?
Our rooflight upstands & kerbs service in Chesterfield covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Neighbouring towns include Staveley (5 km) and Dronfield (7 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Chesterfield?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Rooflight upstands & kerbs in Chesterfield: questions
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Will I need planning permission in Chesterfield?
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.
Is the survey in Chesterfield free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
