Galvanized Steel Roof Panel Vs. Power Lines?

Here in Eastern Washington the customer is responsible for anything past the Meter. Hell, the only thing the locator services I spoke with will locate underground are Public utilities. They will not locate the anything but power & phone out here. I was going to put a fence up. Thanks to all the rocks even a post hole for a rail road tie ends up being a 2'x2' hole. I contacted the locator services....7 times, to come out verify that the phone line was not anywhere close to where I was digging. Never showed up...needless to say I found the neighbors phone line. It was running from the service box to the east of me, directly thru the middle of my property to the neighbor on the west of us.
My father in law lives in Mexico, Mexicali if I remember correctly. He told me wife that when they needed to replace the roof on his house that he had to go looking for a power company truck and slip them some $$ to get them to come out and turn the power off, his neighbors power was running right across his house...touching the roof in spots.
