  • La Roca

    La Roca is produced in Southern Spain by the Villar del Rey company. This slate is an ideal choice for anyone looking for great value for money and a trouble free installation. The slate is black and has very little visible pyrite, giving a stunning finish.

    Please note – This slate is T2 and can therefore rust causing staining on the surface of some slates. This will not affect the performance as a waterproof covering.
