Aluminium Rooflight for Flat Roof Extensions

A flat roof shouldn’t mean a dark room. Our Flat Roof Light is engineered to bring natural daylight straight into flat roof extensions, with the slim aluminium sightlines and weathertight performance the trade expects from us. It arrives ready to fit, so your team spends less time on site and more time moving to the next job.

Here’s where it delivers.

Single-storey extensions. Most single-storey builds have a flat roof, and the centre of a deep extension is always the hardest area to light. A well-placed rooflight pulls daylight into the middle of the room, not just the edges, turning a dark back wall into a bright, usable space.

Home refurbishments. When a roof is already open, it’s the ideal moment to add a rooflight or replace a tired, leaking dome. A clean aluminium unit lifts the whole room instantly and adds lasting value, with none of the warping or rot that comes with older materials.

Orangery-style projects. The flat roof with a glazed centre is the signature orangery look. The Flat Roof Light gives clients that bright, open feel while keeping a solid, insulated roof everywhere else, so you get the daylight without the heat problems of a fully glazed roof.

Kitchen extensions. Kitchens are the most-extended room in the home, and the room where daylight matters most. A rooflight over an island or dining area delivers even, glare-free light and reduces reliance on artificial lighting through the day. It’s a natural fit for the open-plan kitchen diners clients keep asking for.

Trade installations. We’ve kept fitting straightforward, with clear fixing details, slim sightlines clients love, and the weather performance that means no call backs. For fabricators and installers, that’s a reliable upsell on almost every flat roof job, backed by our technical team when you need them.

From a compact single-storey build to a full orangery-style project, our aluminium Flat Roof Light is the low-fuss way to turn a flat roof extension into a bright, welcoming room.

We’ve recently had a Sheerline bifold and lantern installed on our kitchen extension and really stunned with the difference it’s made to how warm and bright the house feels. Really impressed with the service we received, and can’t wait for next summer when we can use the doors properly! Highly recommend.
