Rolesville is a young town by building standards - the median home here dates to 2013, which puts most garage doors on factory-set torsion springs, steel rollers, and openers built with photo-eye safety sensors already wired in. That's a different maintenance problem than you'd find in an older part of the service area. You're not dealing with a 1970s extension-spring door that someone patched twice. You're dealing with a door that was correctly installed once and has had ten or fifteen years of lubrication grease gumming up, nylon rollers wearing down evenly, and sensor brackets working loose from the garage floor settling under a slab poured within the last two decades. The failure mode in a newer house like this is slow and mechanical rather than dramatic. A spring doesn't usually snap out of nowhere on a ten-year-old door - it loses tension gradually, and the opener compensates by straining the motor until that fails too. Skipping maintenance on newer stock doesn't mean nothing happens. It means the first symptom you notice is often the opener burning out, not the spring, because the opener was quietly doing the spring's job for months first.
