Storm Season Gate Failures: What Middle Tennessee Property Owners Should Know

Lightning Is the Big One

The single most common storm-related failure we see is a dead control board after a nearby strike. It does not require a direct hit on the gate. A surge traveling the circuit that feeds the operator is enough.

The symptom is usually total: nothing responds, no lights on the board, keypad dead. Occasionally it is partial, where the operator runs but a loop detector or access control unit is gone.

Surge protection on the gate circuit reduces this exposure meaningfully. It does not eliminate it, and any company promising otherwise is overselling. But relative to the cost of a control board and a service call, it is inexpensive insurance, particularly on rural properties where the run from the house to the gate is long.

Power Loss and Battery Backup

Storms take power out, and a gate with no backup is a gate that does not move. On a property where the gate is the only vehicle access, that is not an inconvenience, it is being stuck.

Every system we install can be released and moved by hand, and we teach every customer how during the walkthrough. But manually releasing a heavy gate in the dark in the rain is not something anyone wants to do twice.

A battery backup will run a typical residential gate through a normal outage. We recommend it on any property where the gate controls the only way in or out, which describes most of the acreage entrances we work on in Williamson and Dickson counties.

Ice Is Harder on Gates Than Homeowners Expect

Middle Tennessee gets one or two meaningful ice events most winters, and they cause damage in two ways.

Limbs come down. Properties with heavy canopy over the entrance, which describes much of Belle Meade, Bellevue, and Leiper's Fork, put gates directly in the path of falling hardwood.

And ice fills tracks. A track slide gate with a frozen track will not move, and forcing it damages the operator. This is one of several reasons we steer customers toward cantilever gates on properties where conditions are rough.

Water Where It Should Not Be

The slower storm damage is moisture. An enclosure that was not sealed properly lets water in over months and years, and the failure shows up long after the storm that caused it.

The same applies to underground operator vaults. A vault with inadequate drainage becomes a sump, and the operator sits in it. In a region with our rainfall, vault drainage is not optional, it is the whole viability of the installation.

Why Rural Properties Take the Worst of It

The storm calls we get skew heavily toward acreage, and there are structural reasons for that.

The run from the house to the gate is long, which means more wire in the ground acting as a path for a surge. The gate is often the only vehicle access, so a failure is not an inconvenience but a genuine problem. Tree cover is heavier, so limb damage is more likely. And the property is more likely to lose utility power in the first place, since rural circuits are longer and more exposed.

Everything in this article applies to a suburban entrance too. It simply matters more at the end of a quarter mile driveway in College Grove or Dickson County than it does on a Brentwood cul de sac.

Is Storm Damage Covered?

Two different questions here and they get confused constantly.

Our warranty does not cover storm damage. No contractor warranty does. Workmanship and equipment warranties cover defects in the work and the parts, not lightning, flood, ice, or vehicle impact. Any company telling you otherwise is describing something it will not honor.

Your homeowner's policy might. Gates and their operators are frequently covered as other structures, and lightning damage in particular is often a covered peril. We are not insurance advisors and we will not tell you what your policy does, but we will document the failure and provide an itemized invoice, which is what an adjuster is going to ask for. Take photographs before anything is disturbed.

What To Do Right After a Storm

• Do not repeatedly cycle a gate that is not responding. If something is mechanically obstructed, forcing it makes the repair larger.
• Check for physical obstruction: limbs, debris in the track, anything against the leaf.
• Check the breaker feeding the gate circuit. A surge often trips it, and that is a free fix.
• Look at the photo eyes. Wind and debris knock them out of alignment constantly, and a gate that will not close after a storm is very often just this.
• If none of that resolves it, call rather than opening the control enclosure yourself. There is line voltage in there.

Before the Next Season

Surge protection on the gate circuit. Battery backup where the gate is the only access. An annual service visit that catches enclosure sealing, battery condition, and drainage before weather finds them. Trimming anything overhanging the gate.

One of our customers had us follow up unprompted after a rough stretch of Nashville weather just to confirm his system was still running clean. That is the level of attention these things warrant.
