Natural Slate

Stunning natural material that can last a century.

For centuries, when people have needed a material that lasts, they’ve chosen natural slate. Neolithic hunters used it to tip arrows and spears. As far back as Roman times, it was being used to roof palaces and forts.


So it’s no surprise that, even thousands of years later, natural slate is still prized for its strength, low maintenance and long lifespan.

The Diamond of the Slate World

Riverstone is a stunning phyllite roofing product that delivers outstanding aesthetics and durability. Subjected to incredible heat and pressure over 560 million years, these geological processes make it harder, denser and stronger than any of the alternatives, including slate. This makes it one of the toughest and longest-lasting roofing materials in the world, and is perfect for when you may have a challenging architectural project to design, or you want that truly prestigious grey phyllitic sheen finish.


The greenest roofing material of them all?

The clue is in the name. Natural slate is 100% natural. It’s the product of hundreds of millions of years of geology, and contains none of the chemicals that many synthetic alternatives do.


When it comes to embodied carbon – in effect, a material’s carbon footprint – natural slate is even more impressive. Concrete tiles create 0.19kg of CO² per kilogram. Clay tiles are worse – they produce 0.43kg per kilo.

Natural slate, however, contains far less – between 0.005-0.054kg per kilo.

If you’re looking for a long-lasting, great-looking roof, then natural slate is the eco-friendly choice.
