I had a TH6 on 60 ft of Rohn 25 up for 3 years in Seattle
on a 30 ft lot. The guys were at steep angles.
It went through lots of big storms with
no problem. The guy anchors were screw in earth type and
the "base" was 5 ft of R25 buried in dirt. One thing
you are suggesting that I wouldn't do is tie guys to the
roof. They will pull your roof off. Instead, bend the
guy over the edge of the roof and continue down to the ground to
a ground anchor. You are of course putting this up without
a permit like I did :-)
