There were no kids or cats out when I sprayed, but as if on cue, after my
post my big white cat woke up, looked like warmed-over crap, then puked
really bright yellow sulphur colored stuff on my floor :/

It isn't just the roses, it affects my native Winged Elm Bonsai as well -
will cover 100% of its leaves. Doesn't seem to hurt the tree particularly,
but ruins the appearance of one of my biggest bonsais for the rest of the
year.

There is probably no really effective organic control for black spot.
Hybrid
tea roses & their ilk require a lot of chemical controls. I use Rose and
Flower
granules for systemic insecticide, which avoids insecticide spraying, but
you
just have to spray for black spot. It is not that dangerous if you just
keep
the kids & the pets away while you are actually spraying. If you are too
fearful, grow something else.
