[Repeater-Builder] polyphaser Help

[KFD29]

Replacing a small, rooftop (about 90ft)  repeater setup.  The prior system had no lighting protection, just straight coax from antenna to duplexer.  I was looking into getting a polyphaser if needed but there is no way to ground it that I can tell.  Two options I have would be to somehow tap into the metal roof and connect it to that? or at the radio-end of the coax attach it to a nearby AC outlet's ground?  A grounding line/rods aren't a real good option since it is on another businesses property.  Any suggestions?
