Lightning is a powerful and unpredictable force of nature that can cause significant damage to homes and structures. As homeowners, it’s crucial to understand the potential risks associated with lightning strikes and take proactive measures to safeguard our properties. At Super Eagle Roofing, we’ve seen firsthand the damage that lightning can inflict and are here to provide insights and solutions.
Understanding Lightning and Its Path
Lightning is essentially a discharge of static electricity between negatively charged particles in a cloud and positively charged particles on the ground. This electrical discharge can reach temperatures of nearly 36,000 degrees Fahrenheit. While lightning can travel directly from clouds to the ground, it often seeks the shortest and most conductive path. This means materials like gas and water pipes, electric lines, phone lines, and even metal window frames can become conduits for this powerful energy. The energy can also “arc” or jump between conductive paths, leading to what’s known as a “side flash.”
The Threat of Fires from Lightning
One of the most immediate dangers of lightning is the potential for fire. Given the extreme temperatures of a lightning strike, any flammable material in its path can ignite. For instance, if a home has gas piping and it’s struck by lightning, there’s a risk of gas leaks and subsequent explosions. However, a well-constructed roof, especially one made of stone-coated steel or metal, can offer significant protection against lightning-induced fires. For homes with traditional roofing materials like asphalt shingles, installing a lightning rod and grounding system can be a lifesaver.
Electrical Systems and Lightning
When lightning strikes a home, it can easily jump to the electrical system, causing explosive surges. This not only damages the wiring but can also destroy plugged-in appliances and electronics. While surge protectors can offer some level of protection against minor surges, they’re no match for a direct lightning strike. It’s always advisable to unplug valuable electronics during a storm to prevent potential damage.
Water, Pipes, and Lightning
Water is an excellent conductor of electricity, and many homes have metal pipes, making them vulnerable to lightning strikes. It’s not just direct strikes homeowners need to worry about; lightning can enter a home through shared pipelines struck some distance away. During a storm, it’s best to avoid activities like taking a bath, showering, or even washing hands to minimize the risk.
Ground Currents and Their Dangers
After lightning strikes the ground, the associated current can travel along the ground for significant distances before dissipating. This ground current can be harmful, especially if it travels through moist concrete or soil. Basements, especially those with wire mesh in the concrete, can be particularly vulnerable.
The Power of Shock Waves
The thunder that accompanies lightning is a result of shock waves caused by the rapid expansion of heated air around the lightning. These shock waves can cause structural damage, especially to brick and stone structures. Chimneys, for instance, can suffer from degraded mortar and loosened flashing due to these vibrations.
Immediate Actions Post Lightning Strike
If you suspect that your home has been struck by lightning, it’s essential to check for fires, especially in hidden areas like the attic. Avoid touching metal frames, pipes, or electrical cords. If there’s any sign of fire or smoke, call emergency services immediately. Once the storm has passed, consider getting a thorough inspection of your home’s roof, walls, and other structures.
