Does this have a built-in bra?

No. It doesn’t have a built in bra.
what is the fabric made out of?

95% Modal and 5% Spandex
Do these stay in place or do they roll up? Is the material thin or thick?

It is a super soft material, they don't roll up on me, but I don't think I've ever had ones that do. They fit close to the body and are very comfortable.
Could it be worn to workout where you sweat a lot?

Yes and no. The fabric is the soft stretchy fabric that feels like it wicks away moisture but excessive sweating may not work. A light workout would be ok.
Does the summer tank top run small or is it true to size?

I thought they run true to size. I just woke mine again tonight and felt comfortable after many washes and keeps original size.
