Answer: Roses require all day sunshine so if yours are not getting at least 8 hours of sun, they just won't bloom. Roses are usually pruned in early spring in such a way as to encourage new flowering shoots. If you are pruning too late in the season, that might affect your shrub's ability to produce flowers. Prune in early spring just as new leaf buds begin to swell on the canes. First reduce the length of the canes to 18-24" from the ground, then completely remove all but the healthiest 3-5 canes. Finally, cut each cane to an outward facing bud in the direction you want the plant to grow. Each cane will produce several new branches, all of which have the potential of producing flowers. As long as your plants are healthy and getting enough sunhine, they should produce flowers.
