Flat Rooflights Brighton & Sussex
Flat rooflights for bright, modern living spaces
Bring natural light directly 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 and contemporary way to bring natural light into an extension or room below a flat roof.
Rather than creating the raised structure of a traditional roof lantern, a flat glass rooflight keeps the roofline visually clean while opening the room below to the sky.
They are particularly effective in modern kitchen extensions, dining areas and open-plan spaces where conventional windows and doors may not deliver enough daylight to the centre of the room.
Why Choose Flat Rooflights?
Maximum daylight with a minimal appearance
Flat glass rooflights combine overhead daylight with simple, contemporary design.
Natural light from above
Bring daylight directly into the centre of an extension where wall-mounted windows may struggle to reach.
Minimal appearance
Flat glass creates a clean architectural finish without the raised structure associated with a roof lantern.
Open views of the sky
Large areas of overhead glass can create a brighter, more open feeling inside the room.
Ideal for extensions
Particularly suited to contemporary kitchen, dining and rear extension projects.
Modern glazing
Insulated glazing helps combine high levels of natural light with improved thermal performance.
Made to suit the project
Rooflight dimensions and specification can be selected around the roof opening and room below.
Flat Glass Rooflights
Let the glass do the talking
A flat rooflight is designed to provide overhead glazing without dominating the architecture of the extension.
Inside
A clean view of the sky
From inside, the rooflight creates an opening directly above the living space, helping the ceiling feel more open and allowing daylight deep into the room.
- 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 well suited to contemporary flat-roof extensions.

Designed for Real Homes
More than just a sheet of glass
A rooflight forms part of the complete roof, so glazing performance, drainage, weathering, installation and the surrounding roof construction all need to work together.
Thermal performance
Insulated glazing helps reduce heat transfer through the rooflight.
Solar control
Glazing specification can help manage solar gain where the roof receives strong sunlight.
Weather resistance
Correct installation and roof detailing are essential to long-term 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 low-pitched roof to bring natural light into the room below. Unlike a roof lantern, it does not create a raised pitched glazed structure.
What is the difference between a rooflight and a roof lantern?
A flat rooflight provides a low-profile glazed opening in the roof, while a roof lantern rises above the roof and creates a more prominent architectural feature.
Are flat rooflights energy efficient?
Modern flat rooflights use insulated glazing designed to provide good thermal performance. The overall performance depends on the glazing, rooflight system and surrounding roof construction.
Can a flat rooflight be fitted to an existing roof?
In many cases it may be possible, but the existing roof structure, opening and surrounding construction need to be assessed to determine suitability.
Do you install flat rooflights in Burgess Hill?
Yes. Sussex Window Works installs flat rooflights in Burgess Hill as well as Brighton, Hove, Haywards Heath, Lewes, Shoreham and throughout the wider Sussex area.
Where are flat rooflights best positioned?
Position depends on the room and roof layout. Rooflights are often placed above kitchen islands, dining areas or parts of an extension where daylight from conventional windows cannot easily reach.
