Local housing stock runs from 1953 up through 2014, with the median build year landing right at 1992. That means a large share of the openers, torsion springs, and track hardware on these doors are thirty-plus years into a service life that was never meant to run maintenance-free. Across the broader area we cover, the stock skews even more heavily toward 1980s and 90s construction - steel rollers instead of nylon, single cable drums instead of double-loop, and lubrication that hasn't been touched since the house was built.
North Richland Hills sits in a moderate-heat climate band, not an extreme one. That matters for what actually fails here. It's not wind-load stress on the door panel - it's heat cycling. Summer after summer, grease hardens, metal expands and contracts, and torsion springs lose tension gradually instead of all at once.
