If the opener is hanging too high, the bar arm that pushes the door down is too tilted. This causes the center of the upper section to bend and bend, leading to damage and the need for replacement. The most common reason for this is that a reinforcement strut was never installed when building new homes. Bad weather can also cause deformation of the panels or misalignment of the door.
This can happen if there are strong winds or heavy rains. Additionally, if you don't research properly when looking for a replacement after the old springs break, you may end up with a door that is too heavy for its own good. It's always best to call a specialist if you want to repair a bent garage door panel. However, if you have the resources, you can do it yourself.
To do this, you will need to fold the door backwards to the other side and place a bit of angle iron. You can then smooth it out with a tool or soapy water on your fingertip. If you don't have an overhead strut installed, this is a very common problem with older wooden garage doors and there's not much you can do about it. However, if you do have one installed, adding another one may be the best option as it provides additional support.
It's important to note that manufacturers have started to use thinner struts for two-car garage doors, so this is something to keep in mind when installing an opener. Additionally, make sure that the arm is securely fastened and that the opener is not installed too high above the garage door.
