OK, recently put on 2 FG comp ‘3tab’ architectural roofs, close to 6/12.
Fairly comfortable doing 3tab ‘freestyle’ with only a 8 foot drop off the edge to grass, no rope. Any steeper or bigger drop would get scary to me. If the bundle wants to slide, it is definitly too steep for me.
Question: How steep is steep to you (obviously 12/12 requires jacks unless you are a ginko)?

6/12 and up requires jacks about every 5'
saw a crew of brazilians roof about 30 square on a 12 pitch with zero staging.... just sneakers
they were done and gone before osha could show up

I took this picture 6 weeks ago from inside my van. I didn't want to scare them off by walking too close taking pictures.
These two were tearing off without toe holds,scaffolding or even a ladder on that side.
Other guys were laying OSB on the other side.
I have seen the quotes from these guys and they work dirt cheap.
This is the same picture, I just cropped it for a closer look.

Why would they need them with an open deck?
I raise my prices at 8/12, but I was walking around on a 12/12 the other day, but I have to use my hands some.

Over 1 story, 7/12 with jacks on the bottom, foam pad to top or walk it to 9/12
9/12 or above jacks on bottom, 6' stepladder on jacks, foam pad to 10/12, over that jacks with room for ladder between.
6/12 when I was young. now a 4/12
I'll work a 6/12 with no jacks. 7/12 gets jacks and planks all the way.
if it is two storeys, I want a jack/plank set at the bottom, and/or a staging around it.
I used to work 8/12 even up to three stores with no jacks or staging.
But that was before I fell that time.
ice and frost change things too. What time of year are we doing this job?

The roofers around here regularly roof 12/12's without anything. I don't have any idea how they do it.
I've got a pair of cougar paw boots. They stick real good. i haven't tried them on a 12/12 yet . I stuck real good to the 8 /12 I was on.
Speaking of roofs. I was using my temp sensor, for fun, to see how how things were last Saturday. The shingles were 115 degrees. The air temp was 106. The black felt on the roof was a whopping 175 degrees! I checked it several times in several places. I was astounded. The galvalume valley metal was only 78 degrees. The underside of the deck was 128 degrees.
Thanks all for your insights. Those pix of 12/12 freestanders seem to be injuries waiting to happen. Even the 6/12 I just did had staging 2 ft below the eave line.
2 years ago when I went back to IL to re-roof 12/12 on mom's house (could not even get anyone to bid then) I even wore harness and roped in in addition to jacks. Mom probably would have been extremely distraught to say the least if I'd injured myself (her dad died in a fall when she was a kid, 1927)
I did my own roof (9/12) 60 squares last year. Jacks and planks at eave and every 5 or 6 feet up the roof. Manlift to install the I&W eave courses and to place the eave planks. Stainless steel achors installed at the ridge: neat things --- a SS strap with D rings on each end -- the strap part is long enough that you leave it on the roof for the next poor bugger who has to do this job, and cover them with the ridge vent material. Snap into the D rings with a carabiner, fall rope, and harness, and you're all set to work.
Manlift to bring up the planks, compressor, gun, shingles. Man does that beat humping this stuff up a ladder, or carrying the shingles up through the interior of the house and out a window, like I did it 30 years ago (same house).
