Understanding what causes these cracks and how to repair them can save you money and prevent further damage. While some fixes are DIY-friendly, others require help from local garage door repair experts.

Common Causes of Cracked Garage Door Panels

1. Impact Damage

Garage doors often suffer dents and cracks from:

• Vehicle collisions (backing into the door)
• Kids playing with balls or other objects
• Severe weather (hail, flying debris)

2. Age and Wear

Older doors (especially wooden ones) naturally weaken over time due to:

• Moisture absorption causing warping
• UV exposure drying out materials
• Repeated stress from daily use

3. Poor Installation or Low-Quality Materials

• Flimsy steel panels dent more easily
• Improperly aligned tracks put stress on panels
• Weak support from broken springs (may need affordable Garage Door Spring Repair)

4. Extreme Temperature Changes

• Metal doors expand and contract, leading to stress cracks
• Wood doors crack when humidity fluctuates rapidly

5. Mechanical Stress from Opener Issues

• A misaligned or malfunctioning motor strains panels
• If the opener jerks violently, consider Professional Garage Door Motor Repair

Temporary Fixes (DIY Solutions)
