In a home with a copper roof, island location, off the east coast. Is grounding of the roof advisable?
If so, describe the recommended method. The building is 40 or so feet tall, surrounded by trees that brush the structure on 3 sides, and neighbors are within 30 feet both right and left. The building is not elevated compared to the surrounding topography. Thanks
