This Spanish natural slate, named Passaro after the quarry it’s selected from, is a high-grade first quality slate with an even surface and a no risk of discolouration. The pre-holed natural Spanish slate is a tough and durable natural material with a uniform thickness that can be installed on pitches as low as 25° in a moderately exposed location and 30° in a severely exposed location. Spanish natural slate has a smooth overall finish and a consistent thickness between 4-6mm which gives an even roof slope. Spanish natural slate samples are continuously tested at the quarry to ensure that it meets BS EN 12326-1 for roofing slate. Acceptable levels of carbon content and a smooth surface combine to make Spanish Passaro natural slates a firm favourite from consistent, traditional and attractive roofs.
