Flat Rooflights Brighton & Sussex
Flat rooflights for bright, modern living spaces
Bring natural light into kitchens, extensions and open-plan living spaces with sleek flat glass rooflights professionally supplied and installed across Brighton, Hove and Sussex.
Light Without the Bulk
A clean way to bring daylight through a flat roof
Flat rooflights provide a simple, contemporary way to introduce natural light into an extension or living space beneath a flat or suitable low-pitched roof.
Unlike a roof lantern, which rises above the roof to form a glazed architectural feature, a flat glass rooflight keeps the external appearance lower and more restrained.
This makes them particularly effective for modern kitchen extensions, dining areas and open-plan rooms where windows and glazed doors around the perimeter may not bring enough daylight into the centre of the space.
Why Choose Flat Rooflights?
Overhead daylight with a minimal appearance
Flat glass rooflights combine useful overhead glazing with clean contemporary design.
Natural light from above
Bring daylight directly into parts of an extension that may receive less light from conventional windows and doors.
Minimal appearance
Flat glass provides a clean architectural finish without the raised glazed structure associated with a roof lantern.
Open views of the sky
Overhead glazing can make the room feel brighter and more open while creating a direct view of the sky above.
Ideal for extensions
Particularly well suited to contemporary kitchens, dining rooms and rear extension projects.
Modern glazing options
Insulated glazing can be specified to balance natural light with the thermal and solar-control requirements of the project.
Specified for the project
Size, glazing and installation details can be selected around the roof opening, surrounding construction and room below.
Flat Glass Rooflights
Let the glass do the talking
A flat rooflight introduces overhead glazing without making the roof itself the dominant feature.
Inside
A clean view of the sky
From inside, the rooflight creates an opening directly above the living space, bringing daylight into the room and visually opening up the ceiling.
- Kitchen extensions
- Dining spaces
- Open-plan rooms
- Contemporary interiors
Outside
Low-profile roof design
The flat glass format provides a more restrained external appearance than a raised lantern, making it particularly suited to contemporary flat-roof extensions.
- Minimal roofline
- Modern architecture
- Clean glazed appearance
- Project-specific sizing
Designed for Real Homes
The glass is only part of the rooflight
A rooflight becomes part of the complete roof build-up. Glazing specification, kerb or upstand details, drainage, weathering and the surrounding roof construction therefore all contribute to the finished installation.
Thermal performance
Insulated glazing can help limit heat transfer. Exact thermal performance depends on the selected rooflight and glazing specification.
Solar control
Where appropriate, the glazing specification can be selected with solar gain in mind, particularly on roofs exposed to strong sunlight.
Weathering & drainage
Correct upstand, roof detailing and installation are important parts of achieving reliable weather performance.

Flat Rooflight FAQs
Common questions about flat rooflights
What is a flat rooflight?
A flat rooflight is a glazed unit installed into a flat or suitable low-pitched roof to bring natural light into the room below. Unlike a roof lantern, it does not form a raised pitched glazed structure above the roof.
What is the difference between a flat rooflight and a roof lantern?
A flat rooflight creates a lower-profile glazed opening in the roof. A roof lantern projects above the roof and uses pitched glazed sections to create a more prominent architectural feature.
Are flat rooflights energy efficient?
Modern flat rooflights are available with insulated glazing designed for good thermal performance. Exact performance depends on the chosen rooflight, glazing specification and surrounding roof construction.
Can a flat rooflight be fitted to an existing flat roof?
It may be possible, but the existing roof structure, opening, falls, weathering details and surrounding construction need to be assessed first. Suitability therefore depends on the individual roof.
Can you install more than one flat rooflight?
Yes, where the roof structure and available space allow it. Multiple rooflights can be useful on larger extensions where daylight needs to be distributed across a wider room.
Where are flat rooflights best positioned?
Position depends on the room and roof layout. Rooflights are often useful above kitchen islands, dining areas or parts of an extension where daylight from conventional windows and doors does not easily reach.
Do you install flat rooflights in Brighton, Hove and Burgess Hill?
Yes. Sussex Window Works installs flat rooflights across Brighton, Hove, Burgess Hill, Haywards Heath, Lewes, Shoreham-by-Sea and surrounding Sussex areas.
