Most garage doors across the Frisco service area went in during a tight window - 1985 to 2015, with the median build year sitting around 2002 - and the 26 named areas we cover are almost all 2000s-era construction. That means a huge share of the doors we're called out on are running their original rollers, twenty-plus years on original nylon or steel, and rollers just don't last that long. Manufacturers rate nylon rollers for roughly seven to ten years of daily cycling; a door original to a 2002 build has been through two or three roller lifespans it never got.
The climate here doesn't help in the way people assume - this is a moderate-heat band, not the punishing extreme some Texas regions see, but summer heat still cooks the factory grease out of steel roller bearings faster than it would in a cooler climate, and repeated heat-cool cycling on the track itself accelerates wear at the curve. It's not one dramatic weather event doing the damage, it's a couple decades of ordinary heat cycling on hardware that was never meant to run this long.
Put those two things together - a housing stock that's mostly aged past original-roller life, and a climate that shortens roller lifespan year over year - and roller replacement is one of the steadiest calls we get across the service area, not a rare failure.
