I'm confused by all the facts. The insurance companies in our area say if you have rods they must be grounded. Many ground rods have the copper wire broke off. I have repaired a barn after a strike, and I sure do not believe a rod was intended to take a strike. The strike took on the rod on the west (top) side of a large barn. It went across the total length of the barn following the cable. It then went to the eve and towards the ground. The path was clear as the asphalt and wooden shingles looked like a mole had dug under to the sheathing. At the eves it took the corner post 8 X 10 in the barn and exploded it. There was no fire, although some charing in the path. Right or wrong we were always told the rods took out the static electricity. It has been explained that if you hold a wire that is grounded, you can rub your feet on a carpet all day and never hear a snap of static electricity. It does make some sence, right or wrong. Most of the older folks will not sleep at night if you remove the rods for roofing. I must say we seldom put them back on now days however it be, right or wrong. With todays copper prices I kind of think it may be worth while to haul them away for scrap. Regardless if they did not work, there must have been some prety good marketing skills involved.
