While the Ham IV (and T2X) are very sensitive to voltage drop, unless
your run is over 100 feet I wouldn't worry about it. BTW, the new Hy-Gain
rotators come with quick disconnect pigtails already.

I'd come in the fascia under the eaves rather than penetrating the roof
and taking a chance on leaks.

Possibly, but it may be connected to PVC somewhere and offer no actual
grounding. If you need to ground the tower, run a big cable down to a ground
stake; nothing else is as good. Don't make sharp bends with your ground
wire; big lazy loops will work but a bend is a high impedance point.
