When the shingles are being used, lay them over the valley flashing, cut completions to the chalk line and nail the shingles a minimum of 50 mm (2) back from the chalk line.

The metal action flashing pieces are rectangle-shaped in shape and style, around 250 mm (10) long and at least 50 mm (2) broader than the face of the shingle being utilized. For instance, when using metal flashing with shingles with a typical 143 mm (5 5/8) exposure (such as conventional 3-tab shingles), the size of the flashing will be 250 mm x 200 mm (10 x 8).
