My eyes see a lightning bolt come from the sky and zap something. But, since voltage is constant (sky) and current flows from the more negative (ground) to the more positive (sky), lightning strikes actually flow from the ground to the sky. I guess that's why people that have been struck by lightning that live to tell about it, say that they could feel something passing through their bodies before the neighbors saw them get zapped.
In theory, the taller the lightning rod, the shorter the distance current has to travel from ground to the voltage source (sky), so the increased chances of being ground zero for a lightning strike. Kind of like standing barefoot in a farm field that goes on forever and ever with no trees for miles and miles, and being the tallest thing during a storm...the lightning rod by default.
My suggestion is to ground your roof, and then to convince your neighbor to buy and put up the tallest flag pole that he can find. Sure, the bangs of close lightning strikes will wake you up in the middle of the night, but your neighbor on the other hand, will be tossed out of bed to your good fortune. If your neighbor asks why he should put up a really tall flag pole, tell him its his patriotic duty, and then walk away while pointing at him and whistling Yankee Doodle or something.
