Garage door rollers can last anywhere from two years to even the lifetime of your garage. Rollers are the objects that attach your garage door to the tracks and allow a smooth operation. Typically, the ones that come with your garage door are plastic or lack ball bearings. Over time, plastic rollers will tend to drag, not roll. This causes friction marks to appear in the track, the door not to run smoothly, and the operator to work harder to open the door. Upgraded rollers are usually made from higher-quality materials like nylon and have ball bearings.
Repairing cables or rollers on your own can be very dangerous, so if you need maintenance or replacements in your garage door system, be sure to call your local garage door repair experts.
