Looks like half of a boomerang to me. And awfully small, compared to your roof, for anything significant
the dome ufo size from 50cm to 1 metre (?) or????? the boomerang size could be 4 to 8m ???
hyper-dimensional plasma jellyfish?
alien bio- object.
If your shutter speed is 1/1000 , then why the blur ? Can we have our resident snoopy camera guy weigh in on this ?
If the object was moving that fast, there is no way you would have seen it. I say HOAX.
