Spanish slate accounts for a high percentage of the slates used for roofing projects in the UK. As an alternative to traditional Welsh and Cornish slate, Spanish slate equals these slates in terms of both appearance and performance. If you’re an architect or roofing specialist and you want the best slates for your next project, Spanish slates from SSQ are an excellent choice.

Why is Spanish slate the superior choice?
Spanish slate is a foliated, metamorphic rock formed over millions of years and of tectonic origin. It is these geological processes that have made Spanish slate the superior material it is and given it its unique attributes when compared to slates from China or Brazil.
Northern Spain has some of the world’s richest slate reserves. The quarries of Orense and the Cabrera Mountains produce vast quantities of slate every year. Spanish slate is used across the world and chosen for its extremely high quality, durability, weather resistance, and attractive aesthetic. A recent survey found that around 90% of the slate used throughout the world today is of Spanish origin.
Spanish slate truly is the premium choice for slate roofs. Durable and versatile, it can be used on all types of roofing installations from the traditional to the contemporary and on both residential and commercial buildings.
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.

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
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
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
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.

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
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.
