Roof slates would have nail holes in them, whereas chalkboard slates probably would not.
A colleague of mine salvaged some Vermont purple slates from a roof of a house that had caught fire. The slates had black stains on them and smelled a little like smoke, but other than that, they were reusable. Of course, stone that is subjected to the high heat of direct flame will crack and disintegrate if the heat is high enough and prolonged.

I am an archaeologist working in New Zealand. I have been excavating an old wooden house burned in a fire in about 1900. There are a few scraps of slate around but not much. Bricks and stone pavers were obviously salvaged from the site but can you confirm for me that roofing slates from a house fire could not be usefully salavaged - they would be ruined, would they not?
So the slate scraps are from children's writing boards (common enough).
hoping you can help me here
