There will be times when your door may fail to operate. It happens from time-to-time no matter how well it is installed and maintained, so there is no need to panic. More often that not, the battery in your garage remote is dead or it is some other simple garage door repair. It is also a good idea to keep additional power back ups with you such as a manual device (generator, UPS, etc) or additional batteries. Or, you can manually open the garage door until you figure out what the is causing the problem.
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.
