"It appears to be about 6:12, which is what my house it."
Agreed. That's what I was thinking when I saw the picture.
That's about 25 degrees, and that is the ragged edge of what someone without experience or the proper equipment should attempt to work on.
I painted steel roof on the house I grew up in back in the 1980s. I was roped off, took my time, was VERY careful, but it was still a gold plated bitch.
There were multiple roof slopes. Several (smaller sections, thank God, that were pretty quick and easy to deal with) were closer to 10:12 pitch, but most of it was in the 6 to 8:12 pitch.
A day of working on that was some of the most tiring work I've ever done. The 7-8 days it took me to clean, prep, and paint the roof? I'm still feeling it nearly 50 years later.
