Normally lightning stikes the highest point but not always. Depends on the storm clouds and the charges that are built up. If your neighbor has a LPS system it doesn't protect your house unfortunately.
The goal is to provide a safe path to ground if lightning hits your house vs it going into the attic, ricocheting like a bullet around your house and maybe killing an occupant.
To make matters worse, lightning can go into your attic, jump to an electrical wire, burn it up then travel down that wire to another circuit, damage that one, etc, until it finds a path to ground. In a case like this you would potentially need to rip your walls open to find the damaged electrical wiring and re-wire. At the end of the day for $2K to install an LPS it's not worth gambling. If you do get hit you are in for a lot of work whether insurance pays. Look at it as one time insurance.
