That is not necessarily true. It is very true for the prima donnas of the rose world ...
I can give you a long list of those, too. Roses are weeds when they are happy.
You do have to find the right rose for your garden conditions. Peter Schneider wrote a wonderful book titled

There are a lot of right ways to grow roses. It's just that for decades all of the information about how to grow roses was directed towards those who had ideal conditions rather that towards people who had real gardens. Roses were sold as if every rose would succeed in every garden. That's never been true about roses or any other plant.
As for roses being heavy feeders, that is not really true, either. Again, for decades, the American Rose Society was dominated by rose exhibitors who threw all kinds of chemicals and followed an intense feeding schedule to get those "perfect" blooms that the average gardener never needed to to do to grow healthy plants. To have healthy roses, you don't need to feed them any more than you do any other plant in your garden. They need the same kind of nutrients you provide your other plants and they will be happy plants.

I can't quite tell from your photo, but I think your red mini is 'Red Cascade'. It was bred by Ralph Moore and introduced in 1976. It can be used as either a climber or a ground cover. It is a weed. It is almost impossible to kill that rose ...
It can die to the ground and will come back.

I can't identify your yellow, but if you want a cold hardy yellow rose that has stood the test of time, you might want to try 'Sunsprite' It is hardy to zone 5. I don't know how well it grows own root, but I do know it was introduced budded.
Rose (Rosa 'Sunsprite')
It can be grown in a container and you can grow it on your patio.
Keep in mind asking a rose to survive road salt is asking a lot of any plant. Centuries ago, salting the earth was one of the ways of destroying an enemy's ability to grow crops as an act of war.
There are roses that are more salt tolerant. As a class, rugosas are often called "beach roses" because of their ability to handle salt spray.
If you are looking for a spectacular red landscape rose I do have a suggestion ...
'New Year' is no longer in commerce and I could not find a peach colored rose with the right bloom form that is currently available. I can find several pink colored roses that would be bullet proof.
