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
Each roller is examined in place before anything is unbolted. The wheel is checked for flat spots, for chips and cracks in a nylon tire, or for a plastic wheel worn to an oval; the stem is checked for bends and for how much it wobbles in its hinge; the bearings are spun by hand for grit, roughness or the loose rattle of balls that have pitted their race. The technician also notes whether each wheel sits centred in the track or has been riding on one lip. Ten or twelve wheels take only minutes to read this way, and the pattern of wear across them tells the story of the door as a whole.
Scene 2
The lowest rollers live in the bottom brackets, and those brackets also anchor the lifting cables, which means they carry the counterbalance load whenever the door is closed. This is the one roller position that is never approached casually. Depending on the door, the technician either exchanges the roller while the bracket stays fastened and the cable stays put, or first takes the spring tension off with winding bars so the bracket can be unbolted and inspected. Either way the bracket, the cable end and the fastening into the section are examined, and a corroded or bent bracket is replaced while the door is already secured.
Scene 3
New ball-bearing nylon rollers on a residential door typically give seven to ten years of ordinary use before they are due again, and sealed-bearing types often longer, while a door that cycles many times a day wears everything sooner. A sensible rule is to have the rollers looked at whenever the door is serviced and to replace them as a set when the springs are next changed, since both wear on a similar timeline and the door is already secured for the work. Industry guidance suggests a professional look at the whole door once a year, with rollers on the list.
What shapes the quoteArmour Heights Door Specialists
FeesSame any hour
Lubricant restores bearings and hinges that are still sound; it has nothing to offer a wheel worn oval, a nylon tire that has cracked, or bearings whose balls have pitted their race. When a spray settles the noise for a day or two and it returns, the wear is in the roller itself and replacement is the answer. Spray on the track or a plastic wheel can make matters worse by collecting grit, so the technician cleans that off as part of the job.
By watching where and when the trouble happens and then checking the parts in that spot. Rollers are spun and wiggled to reveal rough bearings and worn wheels; hinges are checked for cracks, elongated holes and loose bolts; tracks are checked for plumb, dents and spacing. A shudder at the curve tends to be rollers, a pop as sections pivot tends to be a hinge, and a rub the full height of the door tends to be track. Often more than one is involved, and the visit covers them all.
One roller can be changed on its own, and sometimes that is the sensible stopgap after a wheel breaks. The better result comes from a full set, because the other wheels have done the same number of cycles and are close behind, and mixing new with old, or nylon with steel, leaves the door running unevenly and sounding different on each side. A matched set also lets the technician set every top fixture and check every hinge in one pass.
