How we approach flat rooflights in Ilkeston
Thinking about flat rooflights in Ilkeston? The short answer: fixed double or triple glazed rooflights for flat roofs and extensions. The longer answer depends on your roof, which is why we survey before we price.
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 flat rooflights include landings, bathrooms and rear extensions with flat roofs.
Ilkeston is around 12 km from Derby, and we survey and fit throughout that part of Derbyshire, including the DE7 district.
Choices for your Ilkeston project
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Double or triple glazing
- Integral or fitted blinds
- Frame colours: anthracite, black, white or RAL
- Slim sightlines from inside — mostly glass, little frame
- Pairs with an opening unit where you also need ventilation
Things we check at survey
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- The roof membrane must be dressed up the upstand before the unit goes on
Planning, building control and Ilkeston
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.

Common questions
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
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.
Can you work alongside my builder in Ilkeston?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
