As far as most residential garage doors are concerned, you will need at least 10 rollers to operate. This is most especially the case if you have a 7-foot high garage door. But if you have an 8-foot tall garage door, you will most likely need 12 rollers total.
Roller sizes are fairly standard in the garage door industry. Most residential rollers are referred to as two-inch, but the roller diameter is actually closer to 1 3/4 inches. Commercial and industrial doors use two-inch and three-inch rollers. The wheels on three-inch rollers measure closer to 2 3/4 inches.
To see if your rollers need replacing inspect each of the rollers by watching them as they go up and down the track. If one or more are not rolling and or appear damaged it should be replaced. Other signs that a roller is bad: -Grinding noise as the door moves up or down. -Stuttering or jerky motion as the door moves.
As a rule of thumb, it is generally 4 quarter turns per foot. So for a 7 ft. tall door, you will need approximately 28 quarter turns. Granted door weights do vary among other variables.

To put it simply, rollers are available in three material classifications. 1) Urethane/Rubber, 2) Metallic, and 3) Resin. Metallic rollers: These rollers are explicitly designed for sustaining heavy component movement because they can carry a large bearing load with a medium touch.
Although one spring may suffice for lightweight garage doors, most newer models have two.
Torsion springs should be wound four quarter turns per foot of door height, plus an extra two turns. Once you're done winding your springs, keep a winding rod resting on the garage door header and tighten the set screws on the spring with a socket wrench.
This will depend on the type of garage door rollers you currently have. With proper maintenance, rollers can last between 10 and 20 years. Other factors will affect the longevity of your rollers as well, such as weather and frequency of use.
The national average cost of garage door roller installation or replacement is $100–240, including materials and labor. For some garage door pros, this will fall within their basic service fee—which is typically $80–130, plus the cost of rollers.
Other signs that your rollers are overly worn or damaged include irregular or slow garage door operation and noises such as squeaking or grinding. Be sure to inspect your rollers on a periodic basis and have your garage door system professionally inspected at least once a year.
Nylon rollers are a popular choice for residential garage doors. They offer superior noise reduction and better performance than steel rollers. They also require less maintenance than steel rollers, as they don't rust or corrode over time.
A 7 ft tall garage door with a standard 12 inch drum, will require 29-30 quarter turns on the spring. An 8 ft garage door with a standard 12 inch drum, will require 33-34 quarter turns on the spring.
A garage door can become heavy over time due to various reasons. One common cause is the accumulation of dirt, debris, and rust in the moving parts of the door, such as the tracks, hinges, and springs. This build-up can hinder smooth movement, making the door harder to lift.
A garage door typically has one to four springs, depending on the size and weight.
A lightweight single door can usually be supported by one torsion spring. A heavyweight single door may need two torsion springs and double-wide doors need two torsion springs.
How Often Should You Replace Torsion Springs? Most torsion springs last for 10,000 cycles. Depending on how frequently the door is activated, that could translate to nearly a decade or just a few years.
Foam Roller Surface Texture
A smooth foam roller is a good choice for someone who is just getting into rolling because the pressure is not as intense as with a textured roller. Also, smooth foam rollers are typically less expensive than textured rollers.
Each roller has a different thickness of fabric or “nap”, specifically designed for different surfaces around the home. The thicker the nap or length of fabric, the more paint a roller will hold. The thicker the nap, the rougher the surface the roller is designed for.
Combi rollers are, of course, a combination of these two types of compaction equipment. They have a double-drum vibratory roller at the front end and pneumatic tire rollers at the rear. This provides the benefits of both in one convenient machine.
