Allen's housing stock skews newer than a lot of the region - mostly 2000s construction across the subdivisions here, which means most doors and openers are original equipment hitting the end of their expected life around the same calendar years. That's why spring failure clusters the way it does: houses built in the same wave age out in the same wave.
The moderate heat band this area sits in also plays a role, though it's a slower one. Summer heat cycles the steel in torsion springs and dries out the lubricant on rollers and hinges faster than a mild climate would. It's not dramatic, it's not a single bad day - it's a decade of expansion and contraction that shortens the life of hardware that was never rated for a lifetime anyway. Combine builder-grade parts with that heat cycling, and Allen ends up with a steady, predictable rate of spring and roller calls rather than a seasonal spike.
