I know one of my problems is going to be finding a saddle that will work for me at several tasks like roofing, siding, tree work, etc. Why do you think the saddle will not be comfortable when working on a steep 10/12 or gabel dairy barn style roof that you would be "perched" on?
I've never seen a roofer use anything other than fall arrest equipment and many don't even do that if they know OSHA isn't looking. If it's too steep to walk you use roof brackets and planks, scaffolding or a lift depending on the situation.
If I ever saw a guy doing roof work with a saddle he would have to be from some jackleg handyman company that does tree, painting, roofing- anything to make a buck.
