2. Mark the Shingles Lay the shingles flat on your cutting surface. Use a straight edge to mark cutting lines on the surface of the shingles according to your measurements. For best results, use a chalk line for longer cuts.

Cutting Techniques

Once you have measured and marked the shingles, it is time to cut them

1. Cutting Straight Lines For straight cuts, place the straight edge along the marked line. Using the utility knife, score the shingles along the edge. Press down firmly yet cautiously to cut through the first layer. You may need to score multiple times depending on the thickness of the shingles.

2. Cutting Curves or Angles For curves or angled cuts, it is advisable to cut with a combination of scoring and snapping. Score the line deeply, and then flex the shingle until it snaps along the scored line. This method works well for intricate shapes but requires patience to avoid cracks.

3. Trimming Corners For trimming corners, use your utility knife to slice off excess material smoothly. Practice on scrap pieces if necessary to improve your technique.

Additional Tips

- Work in Sections If working on a large area, cut the shingles in manageable sections to maintain control and precision. - Check Alignment After cutting, always check to ensure the shingles fit well before proceeding with installation. Cut any additional pieces as needed to achieve a snug fit. - Keep Work Area Clean Regularly clear your work area of debris and excess material. A clean workspace reduces the risk of accidents and allows for a more efficient workflow.
