I have a roof top junction box, I need to have bare pv wires enter the junction box, how to create water tight seal.. or is there a way to have them enter conduit with bare wires that will create a water tight seal then go into the junction box?

You would use a cable gland.

Ohh also, I am using the gray flexible conduit to go from the box on the roof to down the side of the building into a disconnect, the box on the roof will be within 12" of the edge of the roof (panels will cover it), do I need a conduit strap on the roof itself or can I start using them once I get off the roof and going down the wall?

Flexible conduit can span up to 6' from the termination point (box) before the first strap is required.

Is this on a house? How are you attaching the box to the roof?
It is on a pole barn, the conduit box will be attached to the roof, it is a roof top junction box for shingle roofs.
I would not go through the roof.
I would place the tubes/cables over the edge of the roof and onto the wall under the overhang and then go into/through the wall for less possibility of water intrusion.
With cable glands or similar + silicon etc.
