How to Cut Roof Shingles
- 1). Place shingle upside down with the back of the shingle facing toward you.
- 2). Place a yardstick or a straight metal piece alongside the area you want to cut and mark it with the utility knife.
- 3). Cut along the marking. If the knife does not go completely through the shingle, fold back and forth along the cut until the shingle comes apart.
