Rich, my last location was worse than yours I believe. I lived in an large city two story home with 9' ceilings and a large peak roof, think 1903 style. There was a three story home on the east side and a three story church on the west. Three very large oak trees in the front and very poor aim points to the north. I mounted my tripod on a one story wood shed on the north end of the home. I had about a 60' run of hardline to the shack and used high gain yagi antennas for vhf/uhf. This setup worked fantasy and always was amazing to me. I even pre purchased a Super-Amp SP-7000 for UHF but never found that I needed it. Use some antennas with some gain and I'll bet you'll be just fine mounting on the garage or lower build.
