You will always pull more than 1 g coming out of a roll. If you don't pull
it coming out of the roll, you will have to pull more than 1 g at some point
to come out of the resulting dive unless you want to hit the ground. You can
stay well within the limits if the airframe, but you can go beyond them
pretty easily, too. 1 G is unaccelerated flight-either straight and level or
in a steady climb or descent. You have to pull up slightly to begin the roll
and you will go to less than 1 G when you're inverted to more than 1 G when
you roll upright and return to level flight.

I did some aerobatics in a Decathlon and what surprised me the most doing my
first barrel roll was how slow it was. I thought I would just whip around it
and be done with it, but it took some time to get all the way around. Even
snap rolls were pretty slow. This would no doubt be longer in a 172 with
what I'm pretty sure is a significantly slower roll rate than a Decathlon.
It's the reason I won't try them in my Tripacer. That would be WAY slow
going around and would probably result in more G's coming out.

As for the roll, depending on what type of roll you're performing, you may
well be not pulling more than 1G at anytime if done properly.

Of course I'm not suggesting that you go out and test this.
