What kind of roses grow best in a shady area?
Some shrub roses (Meidiland) take parial shade, but I would explore other more suitable plant options that are likely to perform better, including a vaiety of plant types. Not sure where you are geographically, but shrubs like enkianthus, pieris and itea and perennials like hosta, astilbe and bleeding heart provide flower and foliage inerest.
