How It Shows Up
The first sign is almost always sound - a grinding or clunking as the door travels, worse at the top and bottom of the run where the track curves. Steel rollers on older Kenner doors tend to flat-spot on one side, so the door rocks instead of running straight. You'll also see uneven gaps along the bottom seal, because a worn roller lets that corner of the door drop slightly out of the track. If the door binds and the opener strains or reverses partway through the cycle, that's usually a roller that's finally seized, not a motor problem. None of this fixes itself, and it gets louder and rougher the longer it runs.
What Causes It Around Here
Median year built in Kenner runs around 1977, a few years ahead of the 1980 median across the wider service area, which means more doors here are still running original steel rollers on steel track rather than the nylon rollers that came standard later. Steel-on-steel wears faster and rusts in a climate band like this one - mild most of the year with occasional freeze, which means condensation on cold mornings sits on bare steel rather than evaporating off quickly. That slow rust is what eats the roller stem first, long before the wheel itself looks bad. Doors on this older hardware also tend to have narrower track clearance, so a roller that's worn even a little rides rough well before it would fail on newer gear.
The Cost of This Job
Roller replacement is one of the cheaper repairs we run, and the job itself is usually quick once we're on site - the truck comes from Metairie, about 5 miles out, so travel isn't the bulk of the time, the work is. What changes the cost is how many rollers need swapping and whether the track needs attention alongside them, which is more likely on the older steel-roller setups common on this side of town. With median household income here around $64,099, we try to price roller jobs so a full set swap doesn't turn into a decision between that and something else that month. We don't publish a flat number because the stem length and roller type both affect the parts bill, but we'll quote it before any work starts.
