Supaslate Plastic Roofing Tile


Manufactured in Great Britain, Supaslate is a lightweight plastic alternative to natural slate. Supaslate has been designed to be virtually identical to traditional but with the added benefit of being consistent in weight, colour, size and shape. This makes Supaslate suitable for low pitch installations and is extremely fitter friendly making it perfect for fast installation on outdoor buildings such as sheds, garden rooms, pergolas, hot tub covers, garages and log stores. Supaslate is available in a selection of 6 distinctive colours which have been chosen to best match the vernacular of most properties in the UK.

Supaslate has been designed and tested to be extremely durable meaning that unlike traditional slate they won’t crack and de-laminate over time. Supaslate can be installed on pitches as low as 14 degrees when installed on a fully boarded warm roof system. Weighing in at 7.68 kg per m², Supaslate is less than half the weight of traditional slate and is the lightest synthetic slate available in the UK.
