What Causes Garage Door Sagging?

As garage doors age, they start to look a little less pristine than they used to. In many cases, this simply means sanding and repainting. However, if you have a wooden or metal garage door, you may start to notice that it begins to sag. This can happen on one side or right down the middle, but either way, garage door sagging is an issue that needs to be addressed sooner rather than later.

What Causes Garage Door Sagging?

Garage door sagging can be caused by a number of different things depending on the material your garage door is made from. Sometimes it can even be caused by the garage door opener itself. If you have a sagging garage door, consider the following causes:

  • Exposure – Wooden doors in particular are vulnerable to long-term exposure to the elements. Missouri in particular has some pretty wicked weather. As it goes from hot to cold, the wood can shrink, expand, and eventually warp. This can also be caused by humidity if the garage is poorly ventilated.
  • Trauma or Wear – Garage doors work best when everything is the same. When all the rollers and panels are all the same size, it is a well-oiled machine. However, as rollers begin to wear, it puts more strain on the garage door, causing more wear. Furthermore, if the garage door has collected a series of dents or dings, doesn’t function as it should. Both issues can manifest in sagging.
  • Incorrect Opener – Not every garage door opener is right for every garage door. If your door is too heavy for the opener, a common occurrence in self-installations, it can manifest in sagging as well as many other issues.

If addressed soon enough, many garage doors can be repaired. It can be a simple case of just changing out a panel instead of the entire door. However, no matter what the reason for the sagging is, you will want a professional touch to it. If left alone, sagging garage doors become expensive to fix.
