Since the cold snap the door has been stiff and noisy first thing, and after the last thaw the bottom corner began to judder. There is slush in the foot of the track and a bloom of rust on the lowest wheel.
Winter is hard on rollers. Slush carried in on the tires freezes in the foot of the track, wheels skid across the ice instead of turning and wear flat spots, and salt eats into steel stems and bearings at the lowest positions first. By spring a door that was merely a little noisy is juddering. Roller replacement after a hard season puts fresh wheels and bearings under the door, and the technician clears the salt from the lower track and inspects the bottom brackets and cables that share the same wet corner, so the door heads into the next winter in better shape.

Scene 1
The right replacement depends on numbers taken from your door, not from a catalogue. The wheel diameter is measured across its face: residential track takes a two-inch wheel, while commercial track can take a two-inch or a three-inch wheel depending on the system. The stem is measured from the wheel to its end, and the hinges at each end stile are counted, because a single hinge takes a four-inch stem while two hinges stacked together on a heavier door call for a seven- or ten-inch stem that reaches through both. Stem diameter is confirmed too, since most doors built since the 1980s share one standard size but older doors may not. These measurements decide which set goes in.
Scene 2
The new rollers go in as one set of one type, with the same wheel material, stem length, bearing count and load rating at every position where the hinges allow it. Mixing a couple of new nylon wheels among old steel ones leaves the door running unevenly and sounding different from side to side, so even when only two wheels looked worn, the whole set is normally changed. Where a heavier door needs seven- or ten-inch stems at the double hinges, those positions get long-stem rollers and the single-hinge positions get standard ones, all from the same range so the wheels ride at the same height in the track.
Scene 3
Rollers wear slowly, so it helps to know the early signals. A rhythmic clicking that travels with the door, like a train over rail joints, points to a bearing beginning to fail. A wheel that leans to one side in its hinge, or a door that starts to rock as it rounds the curve, suggests a stem or wheel wearing oval. Grinding that returns a day or two after lubrication means the wear is in the wheel, not the grease. Catching these while the door still runs makes the next roller change a planned visit rather than a door stuck halfway.

Usually, and often dramatically. Rollers are the only part of the door that touches the track, so most of a door's clatter starts there. Moving from worn steel or bare plastic wheels to nylon ball-bearing rollers changes the sound more than any other single part. The rest of the quiet comes from the same visit: hinges lubricated, loose bolts tightened, the track squared so nothing rubs. Springs can still squeak on their own, and the technician can treat those separately.
It depends on what they are made of and how often the door moves. Builder-grade plastic wheels with no bearings often show wear after only a few years. Steel and nylon rollers with seven to thirteen ball bearings are typically rated for ten to fifteen thousand cycles, roughly the life of a torsion spring, which for many households means seven to ten years. Sealed-bearing nylon rollers are rated far higher. A door used many times a day, or one living with salt and slush, shortens all of those.
Yes, and it is one of the main reasons to replace them before they fail. A wheel worn oval, a bent stem, or a short stem sitting loose in a double hinge lets a section drift until the wheel climbs onto the track lip; from there a bump or a gust can carry it out entirely. A door hanging crooked is a far larger repair than a set of rollers. Fresh, correctly sized rollers seated in a squared track are what keep the door where it belongs.
