Eh, going over one layer is fine as long as there are no decking or other structural problems. From what I can see here the older ones are in good enough shape.
Tiles are great, I’d love to have a roof last 100 years. But they don’t get as much use here because of issues with ice damning up the bottom edge and pooling water up under the tile, which then freezes and expands and dislodges or damags the tile. That can be overcome, but it’s easier and cheaper to use shingles.
You should clarify “here” a bit more. In AZ tile roofs are EVERYWHERE.
We end up replacing the underlayment more often than the actual tiles… unless the specific type of tile is no longer made and too many cracked for whatever reason.
And the person who found it isn’t doing a good job either, putting new shingles over old. The old should be removed.

What are those shingles? Pieces of tar?
A fiberglass mat core with asphalt around it and grit stuck in the asphalt on the top.
Huh. We have them and them (old) here.

Well, thanks for the explanation!
