Where is the home located? Are you sure it is coming from the top down or is it coming from the bottom up?

Two things wrong, it's a flat roof, and it's concrete.
With any flat roof it's not a matter of will it leak it's when will it leak.
Did you get a home inspection before buying this?
Call some commecial roofing companys they can lay a one piece rubber membrane EPDM down and stop all the leaks.

What about a neoprene rubber lining? That should work

And this is not a DIY job if you do not want it to leak, your not going to have the tools or the know how.
