The Symptom
Des Moines overall has a median build year of 1995 across the service area, but Altoona skews a bit younger, with a median closer to 1998. That matters for rollers because a late-90s build usually shipped with a steel roller on a stamped steel track, not the nylon rollers that came standard a decade later. By year twenty-plus, those steel rollers have flat spots worn into them, and you hear it as a rhythmic thunk or grind on every cycle, worse in cold weather when the factory grease has stiffened. If your door gets loud only on the coldest mornings and quiets down by afternoon, that's a steel roller in a cold-band climate, not a motor problem. If it grinds no matter the temperature, the roller stem or bearing has already gone, and waiting just wears the track faster.
What It Costs
We don't publish a flat number here because it depends on how many rollers are bad, whether the track needs straightening or replacing, and whether the door is a single or double. A full set on a double door costs more than four rollers on a single. What we can tell you is that most homeowners in this area, with a median household income around $87,123, treat roller replacement as routine maintenance rather than a crisis repair - it's cheaper than a spring job and a lot cheaper than a new door, and it usually gets done in one visit once we're out there.
The Complications
The complication we run into most in homes from this build era is a track that's been bent by the old worn rollers for years before anyone noticed the noise. Straightening or replacing a section of track adds time and parts cost beyond the rollers themselves. Less common, but it happens: a previous owner replaced rollers once already with a mismatched stem length, which means the bracket doesn't sit flush and the new roller binds. We check for that before we quote anything, because guessing wrong means a second trip. One honest limit - if the track is rusted through or badly rusted (less of a concern here than in older stock, but it shows up on doors near grade that sit low), roller replacement won't fix the real problem and we'll tell you straight that track or door replacement makes more sense.
