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

Both products are designed to bring daylight into rooms with flat roofs, but their construction is very different.

A roof lantern projects above the roofline, creating a raised glazed structure that adds height and architectural interest.

A flat rooflight sits flush with the roof surface, creating a cleaner and more minimalist appearance.

While both allow natural light to enter the room below, they create very different visual effects both inside and outside the property.

Why choose a roof lantern?

Roof lanterns are often selected because they become a feature of the room itself.

Benefits of roof lanterns include:

  • Creates a greater sense of height and space
  • Adds architectural character
  • Floods the room with natural light
  • Creates a focal point within the extension
  • Works beautifully in kitchen and dining spaces

Many homeowners choose roof lanterns because they help make an extension feel larger and more impressive.

Why choose a flat rooflight?

Flat rooflights offer a more contemporary and understated solution.

Benefits include:

  • Minimalist appearance
  • Flush external profile
  • Clean modern aesthetics
  • Excellent daylight performance
  • Ideal for contemporary architecture

For homeowners seeking a simpler design, a flat rooflight can be an excellent choice.

Which lets in more natural light?

Both products can dramatically increase natural light levels compared with a solid roof.

However, roof lanterns often allow light to enter from multiple angles due to their pitched design, helping create a brighter and more open feeling within the room.

The overall amount of light will depend on the size, position and specification of the glazing system chosen.

Roof lanterns and kitchen extensions

Roof lanterns are particularly popular in kitchen extensions and open-plan living spaces.

Their raised structure helps draw the eye upwards, creating a greater sense of volume and making the room feel more spacious.

This makes them a common choice for homeowners looking to create a dramatic focal point within a larger extension project.

Flat rooflights for contemporary homes

Flat rooflights are often favoured by architects and homeowners pursuing a minimalist design aesthetic.

Because they sit flush with the roof, they can provide a cleaner appearance externally while still delivering excellent daylight performance internally.

They are particularly popular on contemporary extensions and modern new-build homes.

Which is more energy efficient?

Modern roof lanterns and flat rooflights are both designed with energy efficiency in mind.

High-performance glazing and thermally efficient frame systems help minimise heat loss while maximising natural light.

The overall efficiency of either product will depend on the specific system selected and the quality of installation.
