Avoid a $10,000 Disaster: Signs You Need Lightning Rod Maintenance Right Now
A lightning protection system degrades quietly over time — here are the specific symptoms that mean it's due for maintenance now, not eventually.
Why Maintenance Is the Part People Skip
A lightning rod system works by channeling a strike's energy safely into the ground, but like any system exposed to weather, it degrades over time due to wear, corrosion, and occasionally poor original installation. Because it only has to work during a strike, it's easy to assume it's fine simply because nothing has gone wrong yet — which is exactly how neglect turns into a costly repair later.
Symptom: Visible Damage to the Rods
Bent, broken, or corroded rods are the most obvious warning sign. If you spot cracks, rust, or other visible wear during a walk-around, it's time to schedule a professional look.
Symptom: More Frequent Power Surges
An uptick in power surges, tripped breakers, or damaged electronics can indicate the system isn't diverting energy the way it should. A surge protector helps at the outlet level, but it isn't a substitute for a properly functioning lightning protection system.
Symptom: A Corroded or Worn Grounding System
The grounding electrodes are one of the most critical parts of the system. Rust or visible wear on ground rods is a strong sign that the system's ability to safely discharge energy into the earth has been compromised.
Symptom: New Roof Wear or Leaks Near the System
Missing shingles, dents, burn marks, or new leaks near where rods and conductors attach to the roof can indicate the system didn't fully divert a recent strike — or that its attachment points have failed.
Symptom: An Older System That's Never Been Reassessed
Materials and installation practices have changed over the decades. A system that's gone a long stretch without inspection or upgrade may not offer the same level of protection as one built to current practice.
What Regular Maintenance Actually Prevents
Consistent maintenance reduces fire risk, protects sensitive electronics and HVAC equipment from surge damage, and helps avoid structural repair costs that can run into the thousands. Some insurers may also factor a well-maintained system into how they evaluate risk, so it's worth asking your provider whether you may qualify for any consideration. We recommend a typically annual inspection, keeping rods and conductors clear of debris, and testing the grounding system — call RS Lightning Protection at 1-866-415-2231 to get started.
