These doors can be chain driven either manually or can be automated using electric motors. Roll up doors require more frequent evaluation and servicing than a standard overhead garage door. The tracks that are mounted vertically on both sides of the garage opening need maintenance and cleaning more frequently and are often blocked by foreign obstructions or damaged by collision of some type. These roll up doors are often held open by some type of ratcheting action. Proper balancing of these doors is often more important than an overhead type of door as the weight of these type of doors is normally much greater than an overhead door.
In the past the biggest concern with operating an overhead garage door was the potential risks associated with the springs used for balancing the door weight. Pre mid 1960s garage door installations typically relied upon a pair of stretched (tensioned) springs to assist the operation of the garage door pivoting hinges. These springs became loaded (tensioned) as the door was moved into the closed position. Unloading (releasing) of the stored spring energy occurred as the door was opened to the horizontal overhead position. One of the most dangerous aspects of these spring systems was that after a period of time often without any maintenance or inspection the points of attachment of these springs would rust or become weak.

The date is January 27 2011 and the time is early in the middle of the night. In Dallas TX a family lies quietly sleeping- a husband a wife and their little daughter. In the early hours of the morning the wife awakens and stumbles out of the bedroom to check on their daughter. Perhaps subconsciously she heard a noise. As she walks through the house she notices that the lights in the house were left on. How strange she thinks to herself. In her half awake half asleep stupor however she doesnt think too much of it. Then she notices that the door from the house to the garage was also open and as she walks closer she can see that the garage door is open as well.
