All Flat Roof Windows

Flat Roof Windows Range – Roof Window Outlet

The ideal choice for homeowners, tradesmen and architects, flat roof windows are one of our most popular products – and for good reason. Perfect for awkward, natural light-challenged rooms, such as kitchens –  they encourage natural daylight to flow through your indoor spaces, without compromising the layout or design of your home.

Intended to sit discreetly on horizontal surfaces, flat roof windows improve interior ventilation and utilise your redundant ceiling space, making them popular with style-conscious buyers. They also have a high energy efficiency, and will help you retain your home’s warmth in winter and eliminate excess heat during the summer months. Simply pick your preferred brand, style and size, and we’ll do the rest! 


At Roof Window Outlet, we’re proud to offer the full range of flat roof windows from VELUX, FAKRO Mardome and Keylite – four renowned brands celebrated for their exceptional quality, industry-leading innovation and premium craftsmanship. Our brands cover the glass rooflight spectrum, from curved glass rooflights for contemporary style, to flat glass skylights – all in standard sizes to perfectly fit your project. With varying price points, our extensive collection of top-of-the-line flat roof windows means there’s an option to suit all projects.
