Some facts about slate.
Slate is a dense natural rock or stone material that is nearly nonabsorbant. Slate is collected from quarries from around the world, and cut to size.
Slate rock / stone, is made up of sedimentary particles of clay and silt. Particles settled on the bottom of ancient bodies of water over time forming layers. The pressure of continuous layers along with naturally occurring geological forces, heat etc transformed these deposit layers (shale) into a a harder material, slate. Slate used as a roofing material is separated into different grades per American Standards of Testing and Materials (ASTM).
S1 - service life in excess of 75 years
S2 - service life of 40 - 75 years
S3 - service life of 20 - 40 years.
These standards were developed in the 30's and many in the slate roofing industry find them to be inferior, moves to update the grading process is being pursued. One contention with the standard is that one piece of slate can test differently depending on the area of slate tested. In other words three different results can occur within one slate.
Claims throughout the slate industry state a S1 grade slate can have a service life up to 150+ years, S2 to exceed 100 years, S3 well over 75 years.
