99 year old originally installed slate roof in West Hartford.
Unfading mottled green/ purple slate from the Vermont / New York border.
This was last week, this week I was visiting the quarries where this slate was sourced.
Only about 5% or so of the quarried stone is successfully turned into marketable roof slate.
That means 95% of the stone quarried becomes waste. You can see the mountains of scrap/waste material at the quarry.
