We had a complete lighting protection system installed on our home (Begonia) 4+ years ago. Yes, it has copper rods, down-lines, and 5/8" x 20' ground rods. What my system has that I don't see mentioned on this forum is protection of the secondary wiring systems (i.e., irrigation system, phone/cable system, etc.) (We don't have gas lines in our area.)
Often the lighting damage you hear/read about is TV's, garage door openers, irrigation controls, wired & wireless phones, computers, and so forth. This is often the result of lightning hitting the ground nearby and entering through one or more of these secondary wiring systems. We had a neighbor where the lighting clearly entered via the irrigation wiring. The control box exploded but not before it surged the 120VAC. Took out one of two garage door openers, TV, microwave AND the electric golf cart. Yes, it somehow got through the cart charger and fried the mother board.
Anyway, when talking to any of these lightning protection companies, ask them about 1) bonding of everything metal within 10' of the system into the system; 2) their plans to protect all the secondary wiring systems. If you get that "deer in the headlights" look. Move on.
