How best to remove roof ?

[73Charger]

My SE had a vinyl roof at one time in its life, and I was wondering how I should about removing the rivets left in it that go across the back side.  I was thinking of using a grinder. Would I possibly run into the problem of them breaking away from the roof and rattling around between the roof and the inside metal or is there only one piece of metal there?  I just don't want to make it worse.

Mine was just ground down, never a problem till you want to put the top back on, lol They won't fall out I would just grind down smooth.

OK thanks. I have like a 4" angle grinder I'll use then.
Would it matter if I grind from the top or from the side - as far as not breaking these things?

you can just grind the top they will grind away easily, just be careful when you get to the surface if you have a aggresive grinding disc not to  hurt the surface.
