Slate is a value-oriented manager and a significant sponsor of all of its investment vehicles. As nouns the difference between slate and phyllite is that slate is (uncountable) a fine-grained homogeneous sedimentary rock composed of clay or volcanic ash which has been metamorphosed so that it cleaves easily into thin layers while phyllite is (geology) a type of metamorphic rock formed from clay-rich sediments called pelites. Slate roofing is tremendously popular due to its incredible properties. There are various physical properties of Shale like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The anisotropy is caused by the cleavage plane which is composed of mica layers and thus, highly depends on the mineralogical composition and the fabric of a slate.

Slate is a product with unmatchable technical properties that adapts to any project, always providing considerable added value. One of the unique and aesthetic advantages of natural roofing slate is the subtle variation in color, shade, veining, and grain of each individual slate shingle on a roof. Other strength parameter like the compressive strength or the Young’s modulus are important in respect to safety calculations during mining. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. Slate can be made into roofing slates, also called roofing shingles, installed by a slater in the USA.
