It sounds like they are being attacked by insects or night feeding worms. Most likely insects. I would buy some Bayer Tree and Shrub granules and give some of the granules to each of the rosebushes per the label instructions. Water in well and wash all the foliage down with the cool water. Do not wash the foliage during the heat of the day, do this washing early in the morning or in the coolness of the early evening. This should get the insect issues under control as the systemic action moves through the canes and foliage.
