    Most things that mount to the roof just drill straight though everything and then add waterproofing sealant at the top of the hole/fastener anyway

      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.
