The longer, more in-depth answer: lightning protection systems simply provide a path of least resistance for lightning IF it is going to strike a structure. This safe path to ground enables the surge to travel from the tip of the air terminal (lightning rod) through the conductor, down to ground where it dissipates, leaving the structure unharmed.

Lightning actually does strike the same places more than once. Research leads us to believe it has something to do with ground water and soil composition, but lightning appears to favor the same places over and over. If you have had a strike on your property before, you are more likely to have another strike. There are several other factors to consider before we would tell you that you definitely need a lightning protection system, but having already had a strike is one of the factors that does indeed indicate a possible need for a system.
