A common issue with non windloaded garage doors is over time they sag in the middle. It doesn’t just look unattractive, but it also creates issues with the garage door going down around the radius. The door will bind when connected to a garage door opener. It may also completely collapse the door in the center, leaving you in a position where your house will be unsecured. If your door looks anything like this in the up position, it’s time to replace that door with a new hurricane rated impact door (fiberglass or metal doors).
