no.
If it does, it isn't secured very well. If it slides too easily a strong storm can rip pieces right off your house.
Thankfully, it's fairly easy to re-do, and it doesn't require much in the way of tools or expirience.
Where exactly is it sliding around? does every piece move, or just the pieces near the J-channel at the bottom, or maybe around the doors/windows? Each piece should be attached with roofing nails and then hook into the piece below it, so they shouldn't move laterally.
