The first picture above, shows how the track and roller system can fail due to inadequate anchoring of the track system to the door frame. During a hurricane an unbraced garage door will flex with the wind. In addition to the pressures exerted on the door and the track, the flexing can cause the rollers to become dislodged from its track and the door may fail. Garage door tracks should be attached to the door framing using the proper size anchor and bolt. Check with your door manufacturer or local building official to determine the proper size for your door.
Most manufacturers sell retrofit kits that can be installed for additional bracing.
You can also brace a garage door using 2 X 4's installed horizontally at weaker points of the door. You may also need heavier hinges and stronger center or end supports for your door. Check with a local garage door company to determine the best bracing method for your door. After you have retrofitted your door, it may not be balanced. To check, lower the door about halfway and let go.
