The Stoneleaf Del Mino

The Stoneleaf Del Mino natural roofing slate is produced from quality rock, formed 400 million years ago during the Ordovician period, and coincidentally at the same time as the Welsh slate.

With a 100 year guarantee the Del Mino slate offers you peace of mind that your roof will outlast the life of the building!

In fact, the NAHB (National Association of Home Builders) goes as far as saying that it rates slate as, by far, the longest lasting roofing material, with a life expectancy of 150+ years depending on the slate, followed closely by clay but concrete is roughly up to 100 years.
