Are you feeding your roses? Do they get sunshine all day? Do you see any tiny insects or black spots on the leaves before they get yellow? I would spray them with neem oil which is an all purpose insecticide and fungicide which is very safe. Take off the yellow leaves and remove them from the ground around your plants just in case, because you don't want to return a disease to your plants.
Holly-Tone is a very good, natural plant food for all acid- loving plants. There is also Rose -Tone. These are available at garden center and big box stores.
when watering roses it is best to water in the morning and water near base of the plant not on the leaves directly, this too may help.
