Since the only answer you got so far was snark, and just in case you were serious:
A lightning rod isn't a device that needs to "do" anything to work. It's just a metal rod that sticks up from the top of the dwelling, connected to a grounding rod stuck in the ground, so when lightning strikes, it zaps itself down the rod to the ground instead of hitting the building itself, thus reducing the risk of damage to the building.
It's sort of like that third prong or the little grounding wire that sticks out of the side of some older plugs. It only needs to exist, in order to function, no certification or maintenance needed.
