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.

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.

The slate that’s never failed

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

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

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 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.

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

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

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

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

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

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

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

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.
