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.
What can we learn from this real life crime that occurred in Dallas, Tx? Well, the first question we need to examine is how the burglar got into the home. It all boils down to garage door security. The family had parked their car outside of their home, rather than inside the garage. This gang of burglars evidently would cruise neighborhoods looking for cars parked outside of the garage. Then, as in the case with this attempted robbery, they would simply break the window of the car and grab the garage door opener. That gave them an easy way to directly enter the house.
I have been involved in numerous garage door lawsuits where many different reasons for an injury have occurred. Having been retained as expert witness for both plaintiff and defense, several common factors have been observed. In many cases, unqualified individuals have attempted to repair or install garage doors. They have lacked the knowledge, skills or even the basic required tools to perform the work safely and properly. I have been hired as an expert by garage door manufacturers and installers to defend claims that they are not responsible for alleged product defects. In most cases, the components that failed, failed as a result of abuse or improper installation on the part of the end user. As stated above, the installation of many garage doors is not appropriate for an untrained person.
