Hello Tiffany,
Thank you for your inquiry and the photos. I'm not sure what is going on with the rose. It doesn't look like any of the usual suspects. It almost looks like some kind chemical injury - something splashed on the foliage and petals that caused a scorch. Has anything happened in the area like washing the siding on the house or washing a car nearby? Even mild detergents can burn foliage in the sun.
If the spots don't change or progress in any way then I don't think it is disease.
Here is a good website to help identify rose problems: https://extension.umd.edu/resource/rose-identify-and-manage-problems
See if anything matches your current symptoms.
Sorry I couldn't be more helpful.
