A good slate roof can easily last 150 years and maybe a lot longer.
The four basic elements of a slate roof include:
1) The slate itself. This should be a hard variety with a reputation for longevity.
2) The roof deck. This should be a board deck (not laminated wood) at least 3/4" in thickness.
3) The flashings (the sheet-metal joints between roof planes). These should be copper or stainless steel, although the old "tin" flashings will last quite a long time if kept painted and are easily replaced when they wear out.
4) The nails they should be copper or stainless steel, but cut steel nails and hot-dipped galvanized steel nails will easily last a century or two on a well-maintained slate roof.
These four elements make up a basic slate roof stone slabs attached with nails to a properly sloped wood roof deck and flashed where necessary with appropriate sheet metal. Such a roofing system is very simple, yet amazingly durable and long-lasting.
