When the Texas summer sun starts blazing, it’s not just your AC unit that feels the pressure—your garage door might be feeling the heat too. If you’ve noticed your garage door refusing to close all the way or acting strangely during the warmer months, you’re not alone. The culprit could be something as simple (and sneaky) as thermal expansion or track misalignment caused by rising temperatures.
🔥 Why Summer Heat Affects Your Garage Door
In San Antonio, it’s common for summer temps to soar well into the triple digits. That extreme heat can cause the metal components in your garage door system—like tracks, springs, and rails—to expand. Even the door panels themselves can shift slightly with temperature fluctuations.
Here’s what happens:
-
Metal Expansion: As metal heats, it expands. Your garage door track may slightly bend or misalign, throwing the door off balance.
-
Sensor Misalignment: Sunlight or heat can interfere with safety sensors, making your opener think there’s an obstruction.
-
Swollen Seals or Panels: Wooden or composite doors may swell or warp in the heat, preventing a clean seal or full closure.
-
Lubricant Breakdown: High temperatures can cause lubricants to thin out, increasing friction on moving parts.
🔧 Signs Heat Is Causing Garage Door Trouble
If your garage door isn’t closing all the way, here are a few red flags to look for:
-
Door reverses just before touching the ground
-
You hear loud squeaking or popping sounds
-
One side of the door appears lower than the other
-
The safety sensors blink or flash
-
Manual closing feels jammed or stiff
