    No, most things slide under a shingle so the water never touches the fasteners.

    Some things screw right through with sealant on top, but that’s not the best way to do it, cause sealant will break down over time.

      I agree with you that it is definitely not the best way, by far. However, of all the things I have seen installed on a roof, almost all of them have been installed this way. I think it also depends where you are and what kind of roof you have.
