About Flat Rooflights
Our flat rooflights are glazed edge to edge, so from inside you see a clean pane of sky with almost no frame. Each unit has a strong squareline frame with a built-in thermal break and drainage holes to clear moisture, and the glass is taped and bonded to the frame for security and weathertightness. Sizes run from 750mm square up to 1,500mm wide and 3,000mm long, with frame colours available for inside and outside. A flat rooflight is the simplest way to bring daylight into a flat roof where a lantern would be too tall or too visible. We supply and install them across London and the South East.

Frequently asked questions
Common questions about Flat Rooflights.
What sizes do your flat rooflights come in?
From 750mm square up to 1,500mm wide and 3,000mm long, made to measure for the roof opening.
How do flat rooflights stay weathertight?
The glass is taped and bonded to a squareline frame with a built-in thermal break, and drainage holes clear moisture from the frame.
What does glazed edge to edge mean?
The glass runs right to the edges of the unit, so from inside you see a clean pane of sky with almost no frame.
When is a flat rooflight better than a roof lantern?
When the glazing should sit almost level with the roof and stay out of sight from the garden or the street, or where a lantern would be too tall. A lantern suits the middle of a large flat roof where you want height.
