What Are Rooflights, Skylights and Lanterns?

Rooflights and skylights

Rooflights are fixed or opening glass panels installed on flat or pitched roofs, allowing daylight to flood your interior spaces. “Skylight” is simply another name for the same thing.

Roof lanterns

Roof lanterns are raised, multi-pane glazed structures, often installed on flat-roof extensions and orangeries to create a spacious, bright room with light from every angle.

Roof windows

Roof windows sit within a pitched roof, in a loft conversion or a solid conservatory warm roof, and open for ventilation as well as light.

Our Rooflight and Lantern Options

  • Fixed rooflights – sleek, contemporary glass panels for uninterrupted daylight.
  • Opening rooflights – ideal for ventilation, available in manual and electric options.
  • Flat roof lanterns – energy-efficient glass structures for extensions and orangeries.
  • Frameless rooflights – minimal framing for a seamless, modern look.
  • Bespoke sizes and finishes – made to measure for your roof and frame colour.

Where Rooflights Work Best

A rooflight or lantern can transform any room that lacks natural light:

  • Kitchen and dining extensions with a flat roof
  • Orangeries and garden rooms
  • Conservatories with a solid or warm roof
  • Hallways, landings and bathrooms with no outside wall
  • Loft conversions and rooms in the roof

Benefits of Rooflights and Lanterns

  • Maximise natural light – overhead glazing lets in far more daylight than a wall window of the same size.
  • Energy efficiency – high-performance, thermally efficient glass helps keep heat in and reduces overheating.
  • Modern, elegant design – a striking feature for any extension.
  • Improved ventilation – opening rooflights let fresh air circulate.
  • Increased property value – bright, open rooms are a desirable feature in modern homes.

Planning and Building Regulations

Many rooflights and lanterns can be added without planning permission, within limits on how far they project above the roof. Different rules apply to listed buildings and homes in conservation areas, and new openings in an existing roof may need building regulations approval. We will advise you at the survey.

Installation Process

1. Free consultation and site survey – we assess your roof and discuss the size, style and glass options.

2. Made to order – your rooflight or lantern is manufactured to the exact size of your roof opening.

3. Expert installation – fitted with minimal disruption, and sealed so it stays watertight.

4. Final inspection and guarantee – we check everything is finished properly and hand over your guarantee.

Rooflight Questions

What is the difference between a rooflight and a roof lantern?

A rooflight sits flat or nearly flat in the roof, while a roof lantern is a raised glazed structure with sloping glass sides. Lanterns bring in light from more angles and make a ceiling feel higher; rooflights are more discreet.

Do I need planning permission for a rooflight?

Often not, as long as it doesn’t project too far above the roof. Listed buildings and homes in conservation areas have different rules. We will advise at the survey, and you can check with your local council.

Will a rooflight make the room too hot?

Not with the right glass. We fit thermally efficient glazing that keeps heat in during winter and reduces overheating in summer, and opening rooflights let warm air escape.

Can rooflights open?

Yes. Opening rooflights are available with manual or electric operation for ventilation.

Can you add a rooflight to a conservatory roof?

Yes. Roof windows can be fitted into a solid conservatory warm roof to keep the room bright.
