I use channelmaster 30ft telescopic masts (actually about 27') I use a foot that bolts to the roof and have a socket for the bottom of the pole and swivels to allow you stand the mast up. I then guy it to 4" eyebolts screwed into roof rafters and sealed well with silicone or roof tar. Works great.

The roof is a Metal pitched roof. Every 18" there is a lip where the metal sheets overlap, creating a channel vertically for rain to slide down. The pitch is minimal, almost flat, about 5ft rise from edge to center peak, which is about 75ft wide. 3. The backwall to the ground pavement (2 stories) is also a metal, which has mountable space up top, but loading shop door underneith along the first story of wall. 4. Will be mounting a 12" or smaller panel antenna, fed with Coax. My thought is I'd either use some sort of Tri-pod mount, and fasten straight down onto the roof Peak, about 5-10ft from the back edge. Then use 3 Guy wires spread equally around all sides, such as fasten to peak, and two to the roof's edges. Alternatively, I could use M-Mounts to the wall, with up to 10feet of cantelever leverage below peak, but then I would not be able to put guy wires equally on three sides. (As there would be nothing to tie to on the side over the edge of wall. (Nothing can extend to the ground because of Car Traffic entering into the shop from the back. So what is the best way to mount? Is there a Tri-pod peak mount designed for 20-25ft and guy wires? Is there a support rod option that can get rid of the need to have Guy wires equally on all side, if used wall M mounts? Is this just a combination of the standard Rohn Telescoping Mast with a standard Rohn Tri-pod? Any Best practices for securing Tri-pod down onto Metal Roof? If any vendors have a solution for this, please hit me offlist, for immediate purchase. PS. in the past, for this type install, I'd mount too wall, extend the pole down to the ground, with concrete at the base, but not an option for this job, to go to ground level. Thanks.
