Del Carmen: the slate that started it all
Del Carmen is the sensational natural slate that started it all. It was when our founder, Ahmed El-Helw, first found Del Carmen that the SSQ journey really began.
One of the finest quarries in the most renowned slate-producing region of North-West Spain, Del Carmen produces outstanding slate with a deep blue-black colour that will not fade in sunlight, characteristic longitudinal grain, and highly distinctive, faintly-rippled texture.
That’s why when architects, contractors and homeowners want to crown a property in style, they choose Del Carmen.

Sensational slate, all from the same source
Some quarries mix and match slate from different seams of rock, and even different quarries, then sell it under the same brand name. At SSQ, that goes against everything we stand for. When you buy slate from us, you’re guaranteed the very finest quality – and we can point to the exact seam it came from.

Trusted by the best
When it comes to slate, people are understandably picky. Roofs are a substantial investment – and if you’re responsible for a historic building, or even a national landmark, you’re going to be even more discerning about what material you will and won’t accept.
It’s a testament to the outstanding quality of SSQ’s Del Carmen slate that it’s been accepted for use as an alternative to indigenous slate by Heritage England and Heritage Scotland in a number of cases.
What’s more, it’s also been approved for use by the French authorities – who maintain the highest and strictest natural slate standards in the world.
Slate roofs that could outlive the building
At SSQ, we’re so confident in the quality and longevity of our Del Carmen roof that we’re willing to guarantee it for a century – which, given the average building has a lifespan much less than that, mean a Del Carmen roof may well outlive the property it’s installed on.

Del Carmen has consistently excelled in its testing. Whether it’s the arduous Norm Francais (NF 228), the equally demanding ASTM American standard or the current European Standard (BS EN 12326), we have test results to show its remarkable consistency over the years. As Del Carmen has the much sought after NF 228 status, it has barcode traceability so you can be 100% confident that you’re getting consistent, top quality slate every time. In all the years Del Carmen has been installed in the UK, there’s not been a single registered failure of a Del Carmen roof.

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

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.
Pat Murray, Senior Project Engineer, Alvance Group
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.
