Working Craps program
PEP8

1.Python uses underscore as naming separator in function and variable names, see PEP8

2.Two blank lines are used to separate function/classes

Improvements.

To make your module reusable you should use if __name__ == '__main__' condtion before invoking your main function.

So instead of calling play() you should do:

if __name__ == '__main__':
    play()


Your play_again and play function got difference only in print statements, so you can just combine them into a single function.

def start_game(first_run=False):
    if first_run:
        print("Do you wanna play Craps? Y/n ")
        response = input("&gt;&gt;&gt; ").lower()
    else:
        response = input("Play Again? Y/n &gt;&gt;&gt;").lower()
    if response == "y":
        check_roll(roll())
    else:
        input("ENTER to quit")


Note 

I've renamed function into start_game since I find play a bit confusing. But you can keep your name if you want.

Now if you look at your check_roll and reroll function they are also the same except for win and lose conditions, so you can also combine them into a single one like this:

def check_roll(dice, win_conditions=(7, 11), lose_conditions=(2, 3, 12)):
    if dice in win_conditions:
        print("You win")
        start_game()
    elif dice in lose_conditions:
        print("You lose")
        start_game()
    else:
        print("Time to try to roll the point")
        check_roll(roll(), (dice,), (7,))


Also, I did small improvement to roll() function so now you can see values of dice you've rolled:

def roll():
    input("Press Enter to roll")
    dice = random.randint(1, 6), random.randint(1, 6)
    print("You rolled a {}" .format(dice))
    return sum(dice)


So in the end, what we have is this:

import random


def roll():
    input("Press Enter to roll")
    dice = random.randint(1, 6), random.randint(1, 6)
    print("You rolled a {}" .format(dice))
    return sum(dice)


def check_roll(dice, win_conditions=(7, 11), lose_conditions=(2, 3, 12)):
    if dice in win_conditions:
        print("You win")
        start_game()
    elif dice in lose_conditions:
        print("You lose")
        start_game()
    else:
        print("Time to try to roll the point")
        check_roll(roll(), (dice,), (7,))


def start_game(first_run=False):
    if first_run:
        print("Do you wanna play Craps? Y/n ")
        response = input("&gt;&gt;&gt; ")
    else:
        response = input("Play Again? Y/n &gt;&gt;&gt;")
    if response.lower() == "y":
        check_roll(roll())
    else:
        input("ENTER to quit")


if __name__ == '__main__':
    start_game(True)
