We supply two distinct yet equally impressive grey slates: Riverstone Phyllite and Domiz Natural Slate. Each offers different visual and performance characteristics to suit your project needs.
Riverstone Phyllite (Argentina)
Sourced from our exclusive La Repressa quarry in Argentina, Riverstone is a rare phyllite slate and 100% natural material renowned for:
- A stunning grey tone with a unique phyllitic sheen
- Extreme resistance to UV, fading, and harsh weather
- 100-year weathertightness guarantee
- Non-combustible
- Use in roofing, cladding, and heritage renovations
- Accepted by Historic England and Historic Scotland
Riverstone’s dense structure outperforms traditional natural slate roofing materials in both strength and durability. It’s ideal for demanding projects and conservation work, or if you want that truly prestigious grey phyllitic sheen finish.

Montegris Phyllite (Argentina)
Also quarried and sourced in Argentina, Montegris is also a strong and stunning slate and offers:
- A more cost-effective alternative to Riverstone
- Strong weather resistance and non-combustibility
- 30–75-year material warranty
- Non-combustible
- Grey colour and natural finish
- Perfect for large residential and commercial projects where both cost-efficiency and performance are key.
Montegris’ unmistakable ‘phyllitic sheen’, produced by mica particles that cover its surface, and its hardness and longevity make it a fantastic grey slate roof tile option.
Contact usDomiz Natural Slate (Spain)
Our Domiz slate is quarried and expertly hand-split from the Cabrera Mountains in northwest Spain to offer both strength and beauty. It features:
- High-quality quarried Spanish slate
- A bold, rich blue-grey colour ideal for traditional roofs
- Ideal for a range of challenging applications
- Up to 75-year guarantee
- Clean edges and natural texture
With its striking blue-grey colour and clean edges, Domiz slates are remarkably similar to the now-unavailable Welsh slate from the defunct Ffestiniogg quarry, making it a popular choice in the roof replacement market.

Why do grey slate roof tiles outperform other roofing materials?
Natural grey slate roof tiles are more than just beautiful; they outperform many synthetic roofing materials thanks to their higher durability against wind, frost, and heat; natural resistance to UV and fading; non-combustible, sustainable construction credentials; and longer life expectancy and material warranties of up to 100 years.
Grey slate roof tiles are also an environmentally friendly choice — no chemicals, no coatings, just 100% natural stone.

The choice of SSQ Del Carmen was made easier after confirmation that it had gained approval for use in the Welsh National Parks as an alternative to indigenous materials. We were also pleased with the level of technical, design and on-site support we received from SSQ.
The Hafod Renewal Office
Testimonials
With so many ‘interested parties’ the local planners set their minds on a natural slate roof at a very early stage of the project and, from this starting point, we needed something that would satisfy a number of technical and aesthetic requirements – SSQ Domiz blue-grey, was the one chosen for use to compliment the local ‘Shere Green’ colour.
Ben Hunt, Total Project Integration
Testimonials
We put forward Riverstone as a cost-effective, yet high quality alternative to Welsh Slate, and it was accepted on that basis. The refurbishment work has now been completed and both the owners and ourselves are very happy with the result.
Keith Hicks Architect at Pave Hall
Testimonials
SSQ Rocaber Blue-grey slate was actually chosen at the initial design-concept stage. A natural slate roof was in keeping with the traditional local architecture.
Tom Ewan, Architect at Model Developments
Testimonials
It is a very attractive development and we needed something equally attractive and of equally high quality for the roofing material. SSQ Del Carmen slate is top quality, and we liked the colour and texture. What’s more, it is very good value. I’d have no hesitation choosing it again.
Mr Keith Wills, Clancy's Building Manager
Testimonials
With the roofs being such a visible feature, the choice of roofing slate was a significant decision. We involved the roofing contractor at an early stage in the selection process and they recommended SSQ’s Del Carmen Blue-black slates. Although it’s not an indigenous slate, it is an excellent match for the originals and, having used Spanish slate on other projects, we know the quality is there.
Richard Thorpe, Ridge and Partners LLP
Testimonials
The quality and strength were there, the colour was similar to indigenous Welsh slate and its ‘traditional’ look was in keeping with the surrounding community. In fact, as I had used it on my own Edwardian house, I knew it was a good slate!
Julian Bohling, OSP Architecture
Testimonials
Everyone liked Sarria: the client was delighted with its appearance and its consistency made it easy to cut and lay.
Gary Lambert, Complete Roofing Contractors
Testimonials
We specified SSQ First Domiz Blue-grey roofing slate for both technical and aesthetic reasons:its strength and quality gives the performance needed and its cold, hard, colour provides a dramatic foil to the rich warmth of the western red cedar walls.
Mark Webber, Architect, Nichols Brown Webber

The choice of slates was made easier due to the quality of product you provide and the support of Gary Firth throughout the process – which I much appreciate. Gary is a good ambassador for your company.

SSQ Matacouta slate was chosen as the most sympathetic option. Its consistency and competitive price make it a clear winner over indigenous slates.
