Geneva's median household income runs well above the wider service area's $109,064 figure, which tends to mean more two-car households putting daily cycles on both doors - more open-close cycles per year wears rollers faster than age alone. Combine that with a median build year of 1986 and a cold-moderate climate, and steel rollers here are hitting end-of-life at roughly the same time as other original hardware: the grease dries, the bearing seizes, and a door that's cycled twice a day for most of forty years starts showing it in the track noise before anything else fails. It's not a dramatic breakdown, which is exactly why people put off calling - the door still opens, it just sounds like it's dying every time it does.
