One of the most common problems related to roll-up garage doors is the failure of the pulleys. Pulleys help with the lifting of the door panels as they roll around the drum. When pulleys fail, you need a lot of energy to lift the door panels. Another problem is failure of locks. Locks hold the rolled-up door panels in place to keep the garage open. The locks might fail due to use of excessive force or if they are worn out. Information about Common Problems Associated with Sliding Garage Doors can be found here.
