You can ground your weathervane with lightning conductor cable, which is NOT sold in any store or home building center. The short answer is no, metal roofing is not dangerous and does not naturally attract lightning strikes. A piece of metal sitting on your roof is not grounded, so it would not tend to attract lightning. The lightning rod is connected with a cable to the earth below, where it can channel the charge to a safe place. The wire is connected to a conductive grid buried in the ground nearby. Does Lightning Rod Attracts Lightning In Murrieta? If you have a weathervane on a structure it’s possible for it to get struck by lightning. Fact: Lying flat increases your chance of being affected by potentially deadly ground current. Metal does not attract lightning, at least not in the way some people think. The answer to the first question is “No, weathervanes do not usually ‘attract lightning’ and actually less than a TV antenna does.” If you look around (or remember back a few years), you will see lots of houses with large skeletal TV antennas on them. A lightning rod is a metal strips or rods, usually made of copper, used to protect buildings or structures from a violent lightning strike. A weathervane contructed of copper or aluminum does not make it a target. It connects to a huge piece of copper or aluminum wire that's also an inch or so in diameter. Myth: If trapped outside and lightning is about to strike, I should lie flat on the ground. Think of a pool the size of football stadiium, or much, much larger. The purpose of lightning rods is often misunderstood. While metal does not attract lightning, it does conduct it so stay away from metal fences, railing, bleachers, etc. In a lightning protection system, a lightning rod is a single component of the system. Typically, these antennas are grounded but not part of a lightning protection system. In reality, when lightning strikes, it is seeking a path to ground and almost always will strike whatever object is highest in the area that also has a direct path to ground. Many people believe that lightning rods "attract" lightning. If you are caught outside in a thunderstorm, you keep moving toward a safe shelter. One of the frequently asked questions about weathervanes is whether they attract lightning, and if they are safe when mounted on the roof. Extreme air currents, up drafts and such, create an enormous pools of negative charge in the sky. Lightning will strike when and where it wants to. The misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity, and people, therefore, assume that a metal roof must attract lightning. The highly conductive copper and aluminum materials used in a lightning protection system provide a low resistance path to safely ground lightning’s dangerous electricity. Generally speaking, metal roofing is quite safe. The basic thing to know about lightning is that it always looks for “ground”. It holds no extra attraction to lightning. These materials and components are UL-listed and specially manufactured for lightning protection.
