Hi, whenever I make 1M roses either for cupcake bouquets or for the dome part on giant cupcakes, my roses fall after a while. They slide off the cupcakes/cake, I have no problem when it's on the sides of a regular cake, just on the cupcake bouquet and on the giant cupcake. Is it something on my buttercream recipe or should I put icing on my cupcakes before making the roses. 

Perhaps you need to "crumb Coat" the side of the giant cupcake/cupcake so your rose can attach to it?

Roses?

You mean swirly piped swirls.

I use a crusting buttercream and that always holds better for me. What kind of buttercream are you using.  I once used whipped cream and you could see the slide right offffffff!  Yummy but not pretty!!  And I always crumb coat.

Can it be that your cupcakes are not completely cooled before you pipe the buttercream on them? I'm making a lot of cupcake bouquets lately, and never had a problem of buttercream sliding or even moving at all! No matter if it's a rose, hydrangea or sunflowers, they all stay put! I use SMBC.
