Black spots on roses are caused from mildew and fungus. They need to be watered at the base and may not be getting enough direct sunlight to dry them off when it rains etc. -

"Controlling black spot on roses is crucial to any rose grower. Black spot is a fungal disease characterized by black spots on the upper side of leaves. Tending to occur in warm, wet weather, usually during wet summers, the leaves of infected roses turn yellow and fall off. This weakens the plant by making it more susceptible to other diseases or opening it up to injury for the next winter. The organism responsible for black spot spreads quickly and can move from plant to plant if proper care is not taken." Read more here: https://www.wikihow.com/Control-Black-Spot-on-Roses -

As noted above, it's often caused by water drops lingering on the leaves.... Do NOT water the plant, water the roots! It could be your building(s) are sheltering them from breezes that offer opporunity to dry off, too.
