Understanding Your Roller Door System

Before diving into repairs, it's essential to understand the basic components of your roller door.

Familiarizing yourself with these parts can help you diagnose issues more effectively.

Common Roller Door Issues

Roller doors can face various problems, such as misaligned tracks, broken springs, or malfunctioning motors. Identifying the problem is the first step in the repair process. Listen for unusual noises, check for visible damage, and test the door's operation to pinpoint the issue.
