So I am still in the process of sealing up all my window/roof leaks. Relating to the roof, I removed the drivers side, long aluminum section that covers the roof/upper body seam (a very long drip rail, correct name?) in preparation for resealing. My wife helped me remove it, definitely a two person job. Anyway after it was out of the way my roof up by the driver has about three of large head pop rivets that hold the roof edge to the aluminum frame missing. Today I'm planning on figuring out what happened (just heads snapped off, whole rivet fell out, or oxidized and disintegrated). Whatever the results I need to add pop-rivets back in place to re-secure the roof. Does anyone know the correct rivets to use? I only use closed end rivets on the roof so as to not create another leak point, even though these are covered, and these do have the extra large heads but I am not sure of the "grip" depth I need to purchase. When I get to looking today maybe I can figure it out, but it is very early here in Orlando and sitting here drinking my coffee, I figured I'd ask since I'm sure this has been discussed before but probably under a painting thread or something else to where I cannot find it, so I'm going to ask a related window question in another topic discussion...
Thanks for any assistance,

I believe they are 3/16 diameter and have a grip range of 1/4–3/8”. You can
use a longer grip range rivet iirc because the extrusion you are riveting
into is hollow and fairly large.

I would visit a marine store for your rivets.....you want "splay or claw rivets" and not "pop rivets".....a pop rivet just bunched the material behind it and then releases the center leaving you a hole plus they dont grab that great if the holes are not perfect. A splay rivet will slice open as the plunger or pin pulls up creating a claw and grabs from behind plus the pin doesnt drop out. YMMV and JMO.

So the type of rivet I was planning on using is a closed-end blind Aluminum rivet with Aluminum mandrel with large flange (head). The large flange is usually used on material where there is risk of pull thorough. I do not think this would have been a problem with the aluminum roof, but the GMC engineering thought so I guess. I also see the value of the peel type of rivet, no chance of pull out with a large flange head, but will have a hole in the middle left that I could fill with epoxy I guess. Hmmm... today I will finally have time to investigate what was original by getting inside the coach, and hopefully I will be able to see whats what. I'll let you all know I find and I'll be sure to take a picture or two.

Sorry, I need more coffee. Wondering what to use for these rivets. They are joining the metal oof to the plastic cap, so need more length? How long? And Someone I read somewhere said to use Stainless Steel shank aluminum head blind sealig rivets with an air riveter. Is the air irveter necessary? Hate to buy a $40 tool for one rivet. Just looking for some guidance here on what size/type of rivet to choose and what tool I will need to install.

There are low profile "Blind" rivets, made by Marson Corporation that have
gripping ranges that vary in 1/8" variations. They have a large head for
use on softer materials like plastics. Identified by numbers like L6-4 to
L6-12. THEY ARE CLOSED END RIVETS, NOT HOLLOW TUBES. So, they are somewhat
leak resistant. They are a bitch to cinch up, Marson makes a two-handed
tool called the "Big Daddy" #39031. It will cinch them up. As will a
pneumatic rivet gun. Hope this helps.
