What Causes Cracked Garage Door Panels?

Many different factors can cause a cracked garage door panel. Such as:

1. High Winds

When extremely high winds hit a garage door, the panels can be pushed back and forth quickly and forcefully. This can cause the panel to crack or shift out of alignment, leading to damage over time. It will also further damage the panel if left untreated.

2. Overloading

If you frequently use your garage door to store heavy items, such as furniture or tools, it can put a lot of strain on the panels and cause them to crack over time. To prevent this, it is important to regularly clean out your garage and only keep necessary items in there that won’t put too much stress on the panels.

3. Improper Installation

If your garage door is not installed properly, it can lead to cracks and other types of damage over time. If you notice any signs of an improperly installed garage door, be sure to have a professional take a look at it as soon as possible so that the damage can be repaired before it gets worse.

4. Accidents

If you accidentally run your car into your garage door, it can cause one or more panels to crack. Similarly, if your garage door accidentally gets hit with a large object, such as a fallen tree branch, it can cause structural damage that leads to panel cracks.
