How to Protect Home and Electronic Equipment from Lightning

Lighting can pose a major risk of damage to both renters and homeowners, as it can cause power surges that can damage your electrical circuits and devices. Lighting can destroy electronic appliances, even if it didn’t directly strike your house, as this can send a surge of electricity down to the electrical wires and into your appliances and plugged-in devices. If the strike of lighting is directly on your roof, it may even cause fire into your household.

Because of this, lightning doesn’t only affect the structure of your home and your belongings, but also human lives. Plus, thousands of houses and other properties are destroyed or damaged due to lightning strikes every year.  In this case, you must pay attention to protecting your property against lighting, especially if your area is prone to lightning strikes during storms. Here are some things you can do to protect your home against this:

1. Unplug electronics and appliances during a storm

At the very least, what you can do to avoid lightning damage to your electronic devices is to unplug them in anticipation of a storm. You might be busy at home sometimes and this may not pass your mind, but once you’ve heard thunder cracking, it’s time to unplug in anticipation of the series of lightning strikes that may hit near your area.

2. Check your homeowners/renters insurance coverage

It’s best to be cautious and prepared, but still, make sure your homeowners or renters insurance plans will cover damages caused by lightning. Remember, not all insurance plans are the same, and having insurance that will cover damages caused by lightning is a big plus.

3. Install a home lightning protection system

Simply unplugging will not help, especially when you’re in the middle of something while using an appliance or device. Installing a lightning protection system can help avoid unexpected lightning surges that can damage your appliance or cause injuries. A lightning protection system is a combination of highly conductive aluminum and copper materials used to provide a low resistance path to safely ground the dangerous electricity of lightning. Installing this system can make you receive a credit on your homeowner’s insurance.

A lightning protection system can include:

  • Lightning rods – Made of copper or aluminum, lightning rods are vertically mounted on the roof at regular intervals. These are designed as strike receptors to mitigate the potential damage that may be caused by a direct hit of a lightning strike.
  • Main conductors – Also made of copper or aluminum, these braided cables connect the air terminals to the grounds and other system components.
  • Grounds – These are rods driven at least 10 feet deep in the ground, which is required for all structures. These direct the lightning current to the ground to prevent damage to the structure.
  • Bonds – These joins metallic roof components and grounded building system to the main conductor to ensure conductivity.
  • Surge protectors – These are devices that act as a line of defense to protect electronic devices and appliances from power surges that can cause permanent damage. These range from simple power strips to more expensive units with built-in batteries, which are plugged into an electrical outlet. Your appliances and devices, in turn, will be plugged into the surge protector.

Most of these should be installed by an electrician or a professional, but in the case of surge protectors, you can buy them yourself. Here are some of the best options available on Amazon:
