It's more likely that a home will experience different lengths of electrical spikes from transient to brownouts, etc. or a close lightning strike that goes through the ground and gets into the home than a direct hit. So the most you can do is layer protection even with lightning rods. This includes whole home surge, either behind the meter which your utility has to install and will charge for, or on the electrical panel. This is followed by surge protectors, but these differ in quality. SurgeX is about the best there is and the following link is educational, but go on their website, too. Other than that, unplug if and when you can. In a summer electrical storm when I know the lightning is intense and close, that's what I do, plus when I travel. See this:
