Hello, Bev.....welcome to the forum.
The 'white spots' you speak of, is mildew. A fungal disease that is very common in roses I'm afraid.
Treatment? You'll need to spray with something like 'Rose Clear'.
The reasons your rose blooms may look a tad sad, is because of rain damage......it's always like this with big blousy blooms so it's a good idea to gently shake the water out of them after rain.
