    Roof options for your conservatory in Kent

    The roof is one of the most important components of a conservatory model. Not only will it add significant style to your design, but it also provides structural support to the extension. Our roofing systems, including tiled and glass, are manufactured using well-designed materials that will add strength, energy efficiency and weather-resistance to your conservatory.

    Tiled roofs are available in a number of different colours and finishes, meaning they can seamlessly blend with your home’s current roof. This gives the impression that your conservatory has always been apart of your home. Our tiled roofs offer U-values as low as 0.15, retaining the heat of your home for an ideal indoor living temperature, all year round.

    Popular with homeowners looking for a traditional conservatory appearance, we offer a number of high-performance glazing options for our glass conservatory roofs. With their innovative designs, they’re able to withstand even the toughest of weathers, whilst keeping the cold out and the warmth in.
