The modern, lightweight TapcoSlate tiles used in our roofs are authentically shaped with textured surfaces and riven edges moulded from authentic slates. This makes them almost indistinguishable from natural slate – yet it has an even more refined appearance. They do not crack, break or delaminate, and its product formulation and manufacturing processes provide durability, performance, and longevity for many years to come!

The tiles are available in a range of colours and styles with the most popular shown here, giving you the option to either colour match your homes existing roof or go for something entirely different.
