The Stoneleaf Barco

The Stoneleaf Barco is a natural roof slate with a fine textured surface, blue black in colour with some visible mineral inclusions.

The Barco has been sold in the UK for many years, and with an approximate thickness of 5mm and excellent regularity it has proved popular with roofers due to its ease of fixing.

Due to the regular thickness of the slates the weight per square metre is approximately 31kg and is therefore lighter than many other slates, which can lead to cost savings.
