Roll-up Door Springs: Replacement, and Maintenance Tips


Roll-up doors are a common feature in commercial and residential buildings. They are convenient, secure, and can last for years with proper maintenance. One of the critical components of roll-up doors is the spring mechanism that enables the door to move up and down smoothly. However, over time, the springs can wear out, break, or lose tension, leading to malfunctioning doors.

In this article, we will discuss everything you need to know about roll up door springs, including replacement and maintenance tips.

How Roll-Up Door Springs Work

Roll-up door springs are torsion springs that store mechanical energy when twisted. When you open the door, the springs unwind and release the stored energy, lifting the door. The springs are mounted on a shaft above the door and are held in place by a set of cables. The cables attach to the bottom of the door and pass through the spring’s center, ensuring that the door opens and closes smoothly.

Signs of Worn-out or Broken Springs

Roll-up door springs have a lifespan of about ten thousand cycles, after which they need replacement. The number of cycles is equivalent to the number of times the door opens and closes. Here are some signs that your roll-up door springs need replacement:

  • Difficulty in opening and closing the door
  • Loud squeaking or grinding noises when opening or closing the door
  • Door moves unevenly or appears crooked
  • The door stops midway when opening or closing
  • The springs are visibly worn out or damaged

If you notice any of the above signs, it is time to replace your roll-up door springs.

Types of Roll-Up Door Springs

There are two main types of roll-up door springs: torsion springs and extension springs. Torsion springs are the most common type and are mounted on a metal shaft above the door. Extension springs are mounted on the sides of the door and are responsible for supporting the door’s weight. Torsion springs are more durable and have a longer lifespan than extension springs.

DIY Replacement Vs. Professional Replacement

Replacing roll-up door springs is a hazardous task that requires specific skills and tools. The springs are under immense tension and can cause severe injuries or fatalities if mishandled. Therefore, it is advisable to hire a professional technician to replace your roll-up door springs. Attempting to replace the springs yourself can lead to costly damages to the door, shaft, or cables.

Maintenance Tips for Roll-Up Door Springs

To prolong the lifespan of your roll-up door springs, you need to perform regular maintenance. Here are some maintenance tips to keep your springs in top condition:

  • Lubricate the springs and all moving parts regularly
  • Check the door balance and adjust the spring tension if necessary
  • Inspect the cables for wear and tear and replace them if needed
  • Clean the door tracks and remove any debris or obstacles that may hinder the door’s movement
  • Schedule routine inspections by a professional technician to identify any issues early.
