![]() First, we’ll get started with the positives. Now that we’ve covered exactly what lightning rods do and how they do it, let’s take a look at a breakdown of the major pros and cons of lightning rods. Metal roofs are much less likely to catch fire than wood. While metal roofs are not more prone to lightening strikes than other roof types the roof material of your home can influence how flammable it is. The roof of your home also plays a part in lighting strike safety. If you want to protect from some of the additional effects of lightning such as power surges, there’s more to it.Īt its basics, though, aluminum or, even more commonly, copper is the main component of a lightning rod that gives it its conductivity and, thus, protects your home. This simple design can be expanded upon, though. The most common choices for conductive materials for this purpose are usually either copper or aluminum – more specifically aluminum or copper cable.Ĭopper, in particular, along with alloys of copper are the most often used materials for lightning rods thanks to their ability to conduct electricity effectively. While there are a few different types of lightning rods with different design styles, the materials needed for them are generally pretty common. As such, lightning rods are exclusively made with conductive materials that the electricity from the lightning can travel through effectively. The concept of a lightning rod only works if the rod itself can conduct electricity. Rather, the energy of that strike is diverted safely into a grounding network. ![]() This area is called a grounding network and through this technique, you’re much less likely to experience something like a house fire from a lightning strike. When lightning does strike, though, a lightning rod can work to conduct lightning down the rod so that it can disperse below. These simply aren’t going to keep lightning away from your house. On the other hand, this doesn’t mean that lightning rods will prevent lightning from striking. Ultimately, lightning rods are another tool for homeowners to use to help stave off some of the more dangerous aspects of nature.Īs the name suggests, this particular tool is meant to save you from a lightning strike or, more specifically, save your home plus everyone and everything inside from a house fire started by a strike of lightning. Are Lightning Rods For Roofs A Good Idea?.
