Is this latex and what to do
I started painting a ceiling and the old paint began coming off on the roller. Does this mean the old paint was latex, and what should I do now?

Welcome to the forums!
Are you sure it's paint and not texture?
Can you explain more about the ceiling? Is it in a room that gets a lot of humidity? either from plumbing or open windows?
There isn't a lot you can do other than scrape off all the loose [moisture might make more come loose], patch, prime and paint.

Sounds like you are painting over texture to me as well. Are your ceilings smooth or some thing else?

It very well could be calcimine. Stop and try to wash it off, if it comes, it's calcimine. Nice, you're down to bare plaster and can start anew.

How old is the house and when was it painted last? As a rule, calcimine hasn't been used in 50+ years.
Is the paint pulling off in a spot (or even a few spots) or is all the paint pulling off.

The problem as described suggests calcimine was in the mix at some point, perhaps painted over once before. If so an oil based ceiling product may be in order here.

Good point.
If your house is old, it may have calcimine (paint) down underneath a layer (or two, or three) of latex paint. The calcimine may be getting re-wetted through the porous latex paints on top of it.
If your house is not old, there probably is no calcimine paint, and the problem may be a water leak (or some other issue).

Sometimes too, a previous inadequate preparation job, such as not washing, painting over cigarette smoke, etc., might lead to poor adhesion of the last coat. Thus when you try to paint, you end up with the situation you now have. So try the washing experiment and report back, calcimine or not, you may need to go to an oil based product.
