The Stoneleaf Duero
The Stoneleaf Duero is a natural roof slate which has a riven surface and heavily dressed edges due to being hand split. This gives a traditional look to the roof due to its heavier thickness.
The Stoneleaf Duero, sourced from La Baña, the most prestigious area in Spain for natural slate, is an excellent choice as a roof covering.
The textured surface and heavier thickness appeals to roofers as well as specifiers and developers. With a 100 year guarantee you can be sure that this slate will outlast the lifetime of the building.
