Riverstone Natural Phyllite

Riverstone unfading gray-green is the diamond of natural roofing slate. SSQ’s signature slate is not actually slate, it is phyllite. Harder, denser and stronger than slate, phyllite is a perfect stone for any design challenge or artistic feature.

With only a handful of sources known worldwide, commercially accessible phyllite stone is rare. Riverstone is one of very few top quality phyllite slates available.

Its quality and exclusivity explains why it is used in the most prestigious projects, not just in the UK, but worldwide.

If you are looking for the absolute best – that something special for your roofing, cladding or architectural project – then you have come to the right place.

Like No Other Slate You’ve Ever Seen

Stunning roof design with Riverstone

Riverstone natural phyllite has a slightly coarser grain and a unique satin-like luster

Slate is formed when mudrock is buried deep beneath the earth’s surface and exposed to great pressure and temperatures that would make the mercury in your thermometer boil instantly. When you leave slate ‘in the oven’ for a little longer, it becomes phyllite.

Hand split, just like slate, Riverstone natural phyllite has a slightly coarser grain and a unique satin-like luster, making it the choice of the most discriminating architects across the world.

Just as this satin ‘phyllitic sheen’ helps to distinguish phyllite from slate in the field, it will set your roof apart from all the rest.

Riverstone’s medium grey colour with the slightest hint of green will make your roof as breath taking as it is rare.

View Riverstone on roofs in our Riverstone projects gallery.

There are only a handful of phyllite sources known worldwide, and even fewer that are able to split the stone at the thickness required to be suitable for use as a roof covering material.
