We just have regular 30-year shingles. So I’m not sure how safe they are. We collect the water off the roof for watering flower beds and trees mostly during the dry season.
Just wondering if there was a way to make it potable.

As long as you let water run off for a bit to get the roof cleaned off well, I would do the same with that water as I’m doing with water off my roof.

Depending on the construction of your cistern, it may already be potable.
Screens on sheltered air vents could be all it takes.
Just be sure that you can draw from a point above the bottom so the sediments remain undisturbed.
