The Stoneleaf Cornish Grey
The Stoneleaf Cornish Grey is a natural roof slate with a smooth textured surface, slightly rivened and light blue-grey in colour.
Formed from finely grained metamorphic rock it is popular with specifiers, developers and homeowners due to its eye-catching finish giving depth sophistication to any property.
At approximately 36kg per square metre when laid, the Cornish Grey slate is far lighter than many other roofing products, for example concrete or clay plain tiles can weigh twice as much. By installing slate this can lead to cost savings in the design of the roof structure which benefits the developer, homeowner or self builder.
