Bent or Hanging Gate: Damage from being hit by another vehicle results in a bent or hanging gate. This issue will be difficult to resolve unless you replace the entire frame of your rolling gate, which will cost you more than purchasing a new one. It might be worth it to find a replacement at a reasonable price. However, if your gate has other damage, it would be less expensive to simply replace it. If you are unsure, have the gate-checked out by someone who specializes in driveways gate repair.
Gate Won’t slide on track: Your rolling gate may sometimes become stuck, especially if dirt has gotten into the mechanism’s gears. This is difficult to diagnose without physically inspecting the device, but there may be simple steps to resolve your issue.
Stripped Gears: This is a much bigger issue if your gear teeth are stripped. It can only be fixed if the gears are replaced, as repairing them will not solve the problem. This will be expensive, but it may be less costly than purchasing a completely new system for your driveway gate.
