SSQ’s presence in Slate North America is more than supply - it’s about delivering durable, high quality roofing slate with a unique appearance, tailored to meet the needs of a market that demands excellence. We have supplied slate for many outstanding projects across North America. When the First Presbyterian Church in Red Bank, NJ needed a slate as strong as its heritage, SSQ Riverstone was the clear choice as a timeless testimony of a long tradition. Chosen for its durability and unfading grey finish, it replaced 50-year-old Pennsylvania slate.
From the gothic St. John’s Episcopal Church in Keokuk, IA to Columbus’s Trinity United Methodist Church, our Spanish Del Carmen slate has delivered timeless elegance. And in Beverly Hills , vertical slating using Del Carmen Ultra transforms retail façades into modern architectural statements with unmatched aesthetic and fire resistance.

Testimonials
SSQ Ultra Del Carmen slates come with a 75-year guarantee and that was important. Not only that, the on-site services promised – and delivered – by SSQ enabled a smooth and easy workflow.
Stuart Howes, Architect
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
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
Working in a conservation area brings a special responsibility. SSQ Riverstone slate fits perfectly, its tone and texture blending seamlessly with its surroundings.
Joan Kinane, Architect
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
Being both high quality and cost-effective, Matacouta slate from SSQ is proving very popular with specifiers and contractors alike for refurbishment as well as for new build projects.
Mr Roy Clark, Baxter Clark and Paul
Testimonials
It was an absolute pleasure to meet you today, and I just wanted to take a moment to thank you for your time and a wonderfully informative CPD.
The whole team really enjoyed it, and you definitely conveyed your passion and knowledge of your products!
I would say I will keep SSQ in mind for future projects, but they always have been. However, I have definitely left with a need to utilise more slate in my design work!
Michael Clifton BSc ACIAT - Oakbridge Bespoke Homes Ltd
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
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
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
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
SSQ Matacouta slate was chosen as the most sympathetic option. Its consistency and competitive price make it a clear winner over indigenous slates.
