Shorewood's housing stock runs newer than a lot of the area Minnetonka Garage Door Pros covers - the median build year here is 1986, versus a broader range of 1957 to 2005 across the service territory. That matters for rollers specifically: a door installed in the mid-1980s is now pushing close to forty years on its original hardware, and steel rollers with unsealed bearings from that era are well past the point where they're still running smooth. The failure mode is almost always the same - a roller that's lost its bearing grease seizes partway, then wears a flat spot, and the door starts to bind or chatter instead of rolling. Cold is the other half of it. This area sits in a severe cold climate band, and old grease thickens hard in a sub-zero garage, which is exactly when a marginal roller finally gives out. We see this pattern across the suburbs west of Minneapolis, but Shorewood's housing age puts a lot of doors right in the window where original rollers are failing now rather than in five more years.
