What is Roll Up Door Spring?
A Roll Up Door Spring, also known as a rolling garage door, is a type of door that consists of horizontal slats or panels that roll up and store in a coil above the opening when opened. These doors are typically made of metal, such as steel or aluminum, and can be operated manually or automatically with the help of a motorized opener.
Since they roll up vertically, they don’t swing out like traditional garage doors, which means you can maximize the space both inside and outside the garage.
Another reason to opt for a Roll Up Door Spring is their durability and security. These doors are typically made from sturdy materials, providing excellent protection against intruders and harsh weather conditions.

Type of Roll Up Door Spring
Extension Springs
As the name implies, extension springs store energy by stretching or extending. When the garage door is closed, more weight pan out the horizontal track, adding tension to the stretched extension springs.
Torsion Springs
Torsion springs are placed on the metal shaft directly above the garage door opening. Once installed, aluminum drums are positioned on either end of the shaft. The number of torsion springs to be installed on your garage door ranges from one to four depending on the door’s size (you need to know how to measure garage door springs), strength, and weight.
Standard Torsion Spring
Typically used on residential garage doors, standard torsion springs are installed above the garage opening. Running through the middle and supporting the springs is the metal shaft. If you have a light garage door, one standard torsion spring is usually enough; otherwise, two is should be used.
Early Set Torsion Spring
These torsion springs are placed in the mid part of the torsion shaft. A different type of hardware is installed on each end of the shaft, adjacent to the cable drums.
Steel Rolling Door Torsion Spring
Usually used in commercial buildings, these torsion springs are set within the torsion barrel supporting the rolling door.
Torque Master Torsion Spring
This type of torsion spring is considered the safest among all types. They are enclosed within the torsion shaft and are set in place by a winding cone found at the end of each torsion rod.
How do rolling doors with springs work?
Rolling security doors have springs to help lift them, especially since large doors can be heavy, exceeding 800 pounds or more. The springs are located inside the barrel in the headroom. They use a counterbalance spring system, where the spring is wound from one side to tighten it inside the barrel.
As a person lifts the door, the spring unwinds to provide the counterbalance necessary to open the door. As the door is closed, the spring is rewound and ready for the next door cycle.
As for the springs themselves, there are a few parts you should be familiar with:
Spring: The torsion spring that goes inside the barrel.
Barrel: A steel pipe that contains the torsion spring.
Brackets: The flat, square-shaped steel plates that support the barrel and curtain.
Adjusting wheels: Wheels that apply tension to the spring and are pinned to the bracket to hold the pressure.
Most commercial rolling doors with springs utilize torsion springs to control the up and down movement. The most significant challenge surrounding these springs is that they can wear out or break. Monitoring the performance of the door's springs is essential for operator safety and knowing whether the spring requires replacement or an adjustment.
For particularly heavy doors, a duplex spring may be required to lift them. This means there will be two springs within the barrel, one inside the other. Duplex springs may also be used when the springs needed to lift the door are too long for the headroom area above the door.

How to Replace a Roll-Up Door Spring
If your door has become increasingly hard to operate or you’re hearing a popping or grinding noise during operation, it may be time to replace the spring. When the spring coils become rusted, your roll-up door may not stay open or may be difficult or impossible to open from the fully closed position.
To ensure that you’re able to safely replace the springs in your roll-up door, you should familiarize yourself with the steps necessary to complete the task and make sure that you have the proper tools on-hand for the job. If you feel unsure about any of the steps or tools needed to complete the process, you should contact a professional.
Spring Replacement
To get the correct replacement spring for your door, you should measure the opening of the door. Next, you should measure the unloaded inner diameter and length of the relaxed spring from end to end.
Method 1: Spring Replacement with Removal of Door Assembly
Enter the unit with a ladder and manually roll the door up. Remove the curtain from the guides, tying ropes around both ends of the door to keep it in a tight coil.
If there are 1/4-20 carriage bolts connecting the brackets to the guides, then remove the nuts with the ratchet and the 7/16″ socket.
Use the appropriately sized nut drive to remove the fasteners which secure the brackets to the back plates then carefully bring the door assembly to the ground, remove the cotter pins and brackets from the axle.
Roll out the door to expose the spring.
Remove the bolt, washer, and nut, then take off the spring.
To install the spring, reverse these steps.
Method 2: Spring Replacement Without Removal of Door Assembly
Roll the door all the way down to expose the spring. If there’s an extra sheet, then remove the curtain from the guides and roll the door all the way down to expose the broken spring.
Remove the cotter pin from the end of the axle pipe.
Unbolt the broken spring and remove it.
If there are 1/4-20 carriage bolts connecting the brackets to the guides, then remove the nuts with the ratchet and 7/16″ socket.
Use the appropriately sized nut drive to remove the fasteners which secure the brackets to the back plates.
Hold the axle assembly in place, then remove the bracket and slide the spring off.
Place the new spring over the axel and reattach the bracket.
Reverse the previous steps to finish the installation.
The Mechanics Behind Roll Up Door Spring
When you open the door, the springs release their stored energy, assisting in the lift. When closing, they store energy by winding up. This system drastically reduces the physical effort required to operate the door.
There are two main types of Roll Up Door Spring: torsion springs, which are mounted above the garage door, and extension springs, which are located on either side of the door. Both types are under high tension and are integral to the smooth and safe operation of the garage door system.
Whether a garage door has a second spring or not depends on the specific setup and design of the garage door system.
Single Spring Systems: Some garage doors, especially lighter or smaller ones, may have only one spring. This is often the case with lighter materials like certain aluminum doors.
Double Spring Systems: Many garage doors, notably heavier or wider ones, use two springs. This is common in double garage doors or doors made of heavier materials like wood or insulated steel. The use of two springs helps distribute the load more evenly, providing better balance and reducing the strain on each spring.
How to Maintain Roll Up Door Spring
Maintenance Steps
Now that you’re aware of the problems that can come from having a Roll Up Door Spring, it’s time to talk about maintenance. You can prevent most issues with regular visual inspections. It’s also crucial to keep it clean. Some homeowners find it helpful to invest in a strip door too.
Take the Right Safety Precautions
Before you begin any type of garage door maintenance, it’s important to take the right safety precautions. Put on a pair of work gloves and safety glasses. Disconnect the electric opener to prevent someone from using the door while you’re near it. Never stand near your door while it’s partially open. When it’s not open all the way, the counterbalance system has a tough time keeping the door open.
Perform a Visual Inspection
Once a month, inspect your garage door for signs of rust and corrosion. If any components are dented or bent, stop using the door right away and schedule a repair service. Check the electric opener for signs of oil leakage. If your door is insulated, make sure that the insulation is free from holes and other damages. The last thing you want to check is the weather seals. If they’re compromised, your door could let water into your garage. It will also no longer be energy-efficient.
Keep the Door Clean
The easiest way to keep your door maintained is to clean it. If you allow dirt and debris to build up on the door, it will accumulate on the moving parts and cause them to work harder to function. Leaves and debris attract moisture. If you allow them to gather on your door, it could lead to rust.
