Don Mathis of Macomb, Illinois writes;

Here is a little jig I made for cutting asphalt shingles for cut roof valleys. It consists of two strips of 1/2-in. plywood, one wider that the other. I drilled a series of holes in the ends of the plywood and made a hinge from some plastic cable ties.  That’s it.

To use the guide, I slip an upside-down shingle between the two pieces of plywood, align my layout marks along the edge of the upper layer, and use a utility knife held against the guide’s edge to make my cut.

I use the wire anchor line at the top of the guide to tie it to a scaffold plank to keep the guide form sliding off the roof.

Shep Shep writes: I said this at BT when I first saw that tip in FHB magazine- if you can't cut a reasonably straight line freehand, or using the back edge of a shingle, you shouldn't be doing roofing. If you're shingling a valley, run the shingles long, snap a line where you want to cut, and use a hook knife to cut the shingles.
