Has anyone ever used stainless pop rivets on the stripped out ones? Is it better
to use a lag screw or a larger sheet metal screw. I always thought lags were for
metal to wood fasteners. Has everybody have good luck using the lags & what size
would be the biggest? Has anyone put in additional screws in between the other
striped ones?

I won't comment on using pop rivets on you roof deck. I suspect your
considering pop rivets because using conventional fasteners there doesn't seem
to be a good alternative that is larger than the #14 screws BB used. I found a
successful way to deal with the stripped out screws on my roof deck plate.
After extensive searching I found a stainless steel product called a "Strap
Screw" that is available in a #17 screw size, slightly larger than the #14
screws that BB used. The strap screw has a .10 thick washer under the head that
has an EPDM washer bonded to the SS. These screws fastened securely to the
20+/- stripped out holes I found on my roof.
Source of these fastener includes McMaster Carr (mcmaster.com). Part number for
the 3/4" long Strap Screw is 91644a821. I used 3M #5200 as a bedding compound
for each of the fasteners.
