There undoubtedly penalties to simply GOING to any so-called 'off-limit' areas in an apartment complex. Having a PARTY in any off-limit area is likely grounds for high fines, or even lease termination!
Your best bet is to consult an attorney. I would think if anything were to happen on the roof you would be criminally liable, since you knew the roof was off-limits. However, I am not an attorney or a law enforcement officer.
My advice would be to heed the restriction and stay off the roof.

Penalty of not, the word "off-limit" should be a no brainer. "STAY OFF THE ROOF!" That would ensure you will get no penalties and the neighbors living immediately below the roof will love you for it. Duh!
