What is the minimum slope needed for coping? Is 1/4 " per foot OK?

Also, does all coping require drip edge?

I have seen in all design manuals that coping is sloped towards roof, and away from facade, to prevent water intrusion into wall. What if water is sloped towards facade, but contains drip edge?

Re: Coping

Rule of thumb is the coping cap is sloped back to the roof. ( there are of course some exceptions) The slope factor should be enough for the water to run back to the roof. 1/4" per ft is fine.

It's not just water intrusion into the wall that's a concern is also aesthetics. Over time water running over many different finished wall surfaces will stain the wall and not look too good. Drip edge or not.

There should be a drip edge on both sides of the coping.
