Nope - Tyvek is too slippery to walk on. They'd be nuts to suggest using it on a roof.
I've run across it used as underlayment under a metal roof. It had cooked to where it disentigrated into small pieces when touched. We were tearing of in an exclusive golf course community. What a mess. The roof was about 3 years old and using Tyvek as underlayment was about as close to doing anything right as these guys got.
Titanium and RTGII are similar to Tyvek but designed as roof underlayment.STOP, DROP, ..............ROCK 'N' ROLL
I don't recommend it, but I did use Tyvek once for just that reason. We were doing a tear off and ree-roof on about a 9/12. There was snow in the forecast for that night and we barely had time to strip and resheathe, let alone dry in well. Rather than tarp it down and know how hard and dangerous it would be to pell back the next day, I just grabbed a roll of Tyvek out of the supply. next AM with six inches or so of resh snow pillerd up there. I climbed up and did a tap-tap two or three times and every flake slid right off. Then we layed the tarpaper up as we went along shingling off the brackets. It would have added a couple hours of dangerous work to do it normal.

No, I think they are selling enough Tyvek.
No need to rewrite the code books....AGAIN!
