Lightning Rod Costs
A lightning rod is one component of a lightning protection system that is designed to conduct a lighting strike to earth, thus protecting the building structure.
You will find that the cost to install an average lightning rod depends upon the building dimensions to be protected, grounding circuit length, preparation and special requirements, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
