Roses flower on new growth, but from what you describe you really need to sort out a framework to get the best from your roses. Many people do what you've done but it's easily fixed, just leave it for now, sorting it out is better done when the climbers are dormant as you can see all the main stems and tie them into a framework. creating a framework is easier in winter as well, getting behind a rose in full leaf is difficult to say the least. Best thing you can do right now is plan the framework and get the materials necessary. Decide how much spread you need and consider how high you want it to go. When creating the framework, go as low as you can for the bottom wire and then a foot apart for each subsequent wire. This gives better coverage of the wall, or whatever the background is.You can be quite harsh with mature stems and bend them right down, the new growth will come from between the leaf axils, and grow straight up.
It's all a learning process so don't stress about it and roses are very forgiving.
