    Use an old framing square with your knife. Work on a scrap of plywood with a good edge.

    Cut it on the back side, and then snap it off.

    Flip the shingle over, using a straight edge score the shingle with utility knife then bend and snap. That’s as good as it gets.

    A straight edge helps. They also sell knives made for roofing material. Cut from the back side. I am sure you are going through a lot of utility blades.

    Buy hooked blades for your utility knife. They work very well because you pull the blade up through the shingle.
