I am reworking my roof on the front of my house. The previous roof had been leaking down the corner of the house where the garage and porch roofs come together. The previous roof had a sort of false roof added to create a plane moving away from the sidewall, although this seemed to move the problem down.

I have seen some references to low slope roofing membranes like these: http://www.gaf.com/Roofing/Residential/Products/Low_Slope_Membrane/Liberty, is this the way to go?
I just want to make sure water flows out of this area and over the corner without leaking as shown in the pictures.
