It appears that I am going to have to reroof my house. If my dish is removed carefully, then mounted back in the same holes, if nothing has come loose in the process etc, will my dish still be aligned correctly? One thing it will do is raise it up a bit higher, as we are putting new shingles over teh old. Will I need DirecTV to come out and realign it for me? Or is it a no brainer as long as none of the adjusting nuts/bolts are loosened? Thanks.
