stainless steel roof fasteners
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?

You can get SS pop rivets in any size with large diameter heads at marine stores. They are harder to pull than the conventional rivet and in my opinion will do the better job. After 'pulling' the rivet dab a small amount of silicone in the hole in the head of the rivet.

Don I read your request late today so I'm not going to comment now as it is my bedtime. I've redone several roofs and will gladly go through it with you. If you like you can call me at 951 260-8892 or if you prefer my addy is wander dot rob at gmail dot com. PS never silicon

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.
