Roll crimps reduce pressure slightly but it is hard to know exactly how much in each case. Personnally I will estimate/guess 500 psi on average when using it over a fold crimp recipe. Here is article from Ballistic Products with a few side by side comparisons. As you can see it can reduce pressure by as much as 1500 psi or as little as 100 psi.
