We've been having some wind in Oklahoma the last week or so and yesterday I spotted three satellite dishes that were either partially pulled off of the roof or completely hanging by the coax cable. (and one of them was installed the same way that the original poster's) All of them were "professionally installed" (I know this because I know the people that have the dishes) anyways, I know that sometimes there is no other way to get signal, but I've seen dishes on top of a house that was in the middle of no where (no trees, houses etc.) and still had the dish on the roof. I really don't understand why so many people like their dishes on their roof. 1) When it snows and if you you have any snow fade you have to get a ladder out to clean it off, 2) wind, no matter how big the screws you use, will and do rock the dish back and forth, which is bad on your roof material, and eventually will cause the dish to need to be re-adusted, and you CAN'T remove the dish from your roof without doing some patch work because you now have holes from the screws that can and will leak, 3) if you ever have to replace your roof (should have to every 10-25 years) you will have to either re-install the dish or pay to have it reinstalled, along with worrying about something getting tore up (the dish, cables etc.) in the process of re-roofing your house. IMHO a dish should never be put on a roof unless absolutely and positively neccessary, which IMO is very seldom.
