Every 5 inches make a new mark until you get to the rop of the roof. High wind areas and other types of shingles may need more. Do this on both sides of the roof. This will allow the flashing piece to move independently of any differential expansion and contraction that may occur between the roof deck and the wall.

However shingles are packaged in a way that they are light enough for the average person to carry around. Because the bending can stress and deform shingles especially in cold weather the ends of those shingles may warp over time creating a prominent pattern on the roof. Row 7 begins with a full 3 tab shingle. Use the chalk line to snap a straight line vertically every 6 inches.

To attach a 3 tab shingle align it with the layout line and drive nails 1 2 inch above the cutout slots including the half slots at each side. Repeat this on both sides of the roof. Pattern curling is caused by the roofer having to lift the end tab of every other shingle to install the last shingle nail at the end of the next shingle.
