A roll-up barrier has a base, an end cap, a drive shaft connected between the base and the end cap, a rolling assembly, a resilient element and a flexible barrier. The end cap has an arresting mechanism having a control button and an arrestor. The rolling assembly is mounted rotatably around the drive shaft and has a rolling bushing. The rolling bushing has an actuator and multiple one-way arresting teeth. The resilient element provides a reposition force for rolling back the rolling assembly. The flexible barrier is mounted retractably around the rolling assembly. When the control button is pressed and rotated, the actuator detaches the arrestor from the arresting teeth to allow rotation of the rolling assembly. When the control button is released, the arrestor engages the arresting teeth to prevent the rolling assembly from rotation so the flexible barrier can be pulled out and held at a desired length.
