Looks like it's quite shaded and also being choked out with all the other plants at it's base, impeding the air flow around the plant. If you can clear some of that out, you can then add a layer of compost mulch and cut the rose back in the winter, maybe by half.

We actually just got this house about 2 years ago so I have no idea what type of rose it is or how old unfortunately....but thank you all for the info I figured the other plants had something to do with it. I'll see what I can do about it later today.
We got a drench for that, but when the stuff melted the surface of a plastic measuring spoon, we gave up that idea. Instead, we did what local avocado growers do for avocado root rot (a closely related fungus). We got FRESH horse manure from a stable. Piled it around the base of the plant, from a few inches away from the base all the way to the drip line. That did the job.
I agree that the plants all around it need to be cleared away, and I would feed the rose. And you need to cut off all of the dead canes. (Dead stuff isn't helpful.)
I would also ask what rose this is?
How old is the plant?
What did the blooms look like LAST year?
What did the blooms look like THIS year?

Is that bloom you showed the "deformation" you were mentioning? That's called "proliferation," and some roses will do it.
Were this year's blooms the same color as last year's blooms? Last year, they were pink. Were they still pink, this year?
And . . . . Did you plant this rose, or was it there when you bought the house? If you planted it, can you remember its name?
