We toted two adult mountain bikes on a ladder rack for two years and over 20,000 miles. The ladder and mounts are plenty strong to handle it. The biggest drawback for me was having to remove the bikes to go up on the roof. And we only used the bikes once in two years so we gave them to one of our kids and his family.
I also had a situation with our first Montana, detailed in another thread, where I essentially put the bikes too low on the rack, caught a bike wheel on a driveway and pushed it up at least a foot. There was some damage to the ladder's tubes but none at all to the Montana and its mounts. The moral is to be sure the entire bike is above the bottom of the ladder.
I'm totally convinced the ladder is plenty strong to handle it. But I did not like having to remove the bikes to get to the roof.
