Ahh it get to be spring and a man’s fancy turns to roofing.
Over at the big boy tool store they sell these deals that they call roof anchors or something like that. They have them in permanent and temporary style. You tie your rope to them I suppose.
I am thinking of buying one permanent and one temporary anchor. I will then mount one near the east end of the roof and the other at the west end. I plan to run a chain/cable from end to end. Now I am going to tie my safety rope or lanyard to the chain between the anchors.
This setup will last until near the end of the job when I move the permanent one to near the chimney at the center of the roof.
Would the OSHA man approve?
Should I mount on the ridge or on the flat?
Two or three layers of tear off, a new deck layover, tar paper…

My guess is no unless the equipment is specifically designed and manufactured with that use in mind. But I'm only guessing.
I think I would mount them each about one quarter to one third of the way in from the ends and hook up directly to whichever one I'm closest to.
"Should I mount on the ridge or on the flat?"
The only roof anchor I've used has very specific instructions on how to use it. It can be mounted either over the ridge or on the flat (but if memory serves, the instructions had a strong preference for over the ridge.
It's hard to believe that you can buy a roof anchor without instructions.

Nope.
The Tie off needs a 900 lbs. min , tied to the ridge. It must be an eye, and 8 # 10 3'' screws into a truss or rafter IIRC.
We use Miller systems (saftey in a bucket)? type Fallarrest...maybe Greencu can tell ya...he bought em..about 120 simoles a shot for all that ya need.

Interesting, You want to hook yourself up to some kind of roof mount clothesline style dog run. Sphere says you need 900lbs per but with a cable you would be splitting the weight between both tie downs. In a dead center fall your system would be stronger, yet you would fall farther because of the flex in the cable. How the thing would actually perform in a fall... for example... would your weight drag you to center if you fell near the edge? Would your tether sweeping across the roof knock a co-worker off his feet as it dragged to center?
OSHA, the Army Corps Of Engineers, and the Safety Engineers on every union highrise job I've ever been on have not had a problem with yo-yo's attached to a cable between two points. As long as every part of the fall arrest system met the required standards. I would definately recommend using a yo-yo lanyard, that will prevent most all the concerns mentoned by others.
