Hi. I do have a leak coming from my flat roof and tomorrow I'm supposed to have a rip and install job. My Slimline SW3 is there. The contractor that is doing the job seemed content to just put the dish back after they do the roofing job. Another contractor told me I shouldn't do it and that it voids the GAF warranty as well. He suggested mounted it to the fascia of the house or some other way. He also said that the water problem I 'm having could in fact be from the dish and may have traveled. Who knows... Should I call DirecTV and ask for another install option? I appreciate the input.
