I see someone else long ago asked the same question, but this is a little different. Finally talked a friend into going HD, got a deal with Directv, and installer shows up. Old 101/110/199 dish mounted on eave and he looked at it and said, according to my friend, that he couldn't mount it on a house with a metal roof. Friend adamantly refused pole install as he really didn't want a pole in his yard but mostly because he didn't want to pay the guy $75 so he sent him on his way. So I guess he and I will be doing the install now if he wishes to proceed. Now I assumed he could mount it on the eave where the other one was--question is, is there anything about a metal roof (other than don't attach to it because of structural integrity and movement) that I'm missing. Friend wasn't sure exactly what he meant when he said it and he had just learned of a death in his family and didn't really want to mess with this guy. If he couldn't mount it on the house, shouldn't the pole install be free? Thanks.
