  • Calidad 120 Roofing Slate

    Sourced in Northern Spain, our Calidad 120 slate is almost identical in appearance to traditional Cornish slates, which gives a great alternative for projects where fitting in with surroundings is crucial.

    This slate is a great alternative to roofing with Delabole or Trevelitt slates, giving authentic appearances combined with the best functionality and longevity. This slate is incredibly popular in the South West of England, but it can easily give you an authentic look, wherever you are. With shade variations from blue/green to blue/grey due to the nature of the quarry, giving the rock a similar appearance to that of native Cornish slate, you can get a great looking slate at the fraction of the cost and without a compromise on quality.
