An exclusive slate from the Del Carmen quarry in the Cabrera Mountains of North-West Spain, it is consistently hand picked by architects around the world for its unrivalled beauty and exceptional high quality. The unique colour is totally natural and will not fade, even in the strongest sunlight.

Unlike other slate brands, every Del Carmen slate comes from the same uninterrupted seam of high quality stone. Other brands may substitute slates from different quarries and different seams – when it comes to Del Carmen, there are no substitutes.

We know that you need to be able to rely on the roofing slate you select to be consistent in terms of quality, effectiveness and sheer beauty… and with Del Carmen, that’s exactly what you get.

Guaranteed To Outlive The Building

When it comes to choosing what to put on your roof, there should be no risks involved. That’s why we bear all the risk and guarantee your Del Carmen roof for up to 100 years. With the average lifetime of a building being considerably less than that – your roof is guaranteed by SSQ to outlive the building.

We are able to do this because we know from experience that your roof will last. There has never been a single recorded failure of Del Carmen (either as a fit for purpose roofing material or from an aesthetic perspective) in the US or abroad.
