Quick Answer
A recommended height for lightning rods is typically 10-16 feet above the highest point of the structure, but should be at least 3 feet above the roof and 3 feet higher than any nearby obstacle.
Mounting Considerations
When installing a lightning rod, proper mounting is crucial for its effectiveness. The rod should be securely attached to a sturdy, grounded object, such as a metal mast or a lightning rod base. This attachment point should be at least 3 feet away from any nearby conductive objects, such as downspouts or gutters. For solar installations, consider mounting the lightning rod near the solar combiner box, but not directly adjacent to it.
Height Requirements
A lightning rod’s height is critical to its function. A minimum height of 10 feet above the highest point of the structure is recommended, but 16 feet is even better. This height allows the rod to attract lightning and safely direct it to the ground, reducing the risk of damage to the structure and nearby equipment. For solar installations, consider using a taller lightning rod to account for the height of the solar panels and the combiner box.
