Flat rooflights for Kirkby in Ashfield: the essentials
We handle flat rooflights across Nottinghamshire, including Kirkby in Ashfield. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Typical uses for flat rooflights include kitchen extensions, side returns and flat-roofed back rooms.
We work across Nottinghamshire, including Kirkby in Ashfield, and in neighbouring towns such as Sutton in Ashfield and Mansfield. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Kirkby in Ashfield?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about flat rooflights in Kirkby in Ashfield
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
How do I book a survey in Kirkby in Ashfield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Kirkby in Ashfield?
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.
