ABSTRACT:
A shingle is formed with a first, or trailing, side edge folded over toward the top surface of the shingle to catch moisture and direct it down to the top surface of the next lower shingle. A second, or leading, side edge of the shingle is not folded. An "S" shaped fold, spaced apart from the trailing edge fold, receives the unfolded leading edge of an adjacent shingle. The trailing edge and S fold form a gutter under the leading edge of the adjacent shingle. The top edge of the shingle is folded-over toward the top surface of the shingle for engagement with the folded-under lower edge of the next higher shingle. The folded-over top edge extends to the right or leading edge of the shingle and slides under the left edge of the folded-over top edge of the next adjacent shingle to the fight side. The folded-under lower edge extends along the lower edge of the shingle but leaves a gap relative to the folded-under lower edge of the lateral adjacent shingle. In this way water is caught by the gutter and flows out the gap between folded-under lower edges of laterally adjacent shingles. One or more S-shaped folds are also made in the middle of the shingle to form a panel having the appearance of multiple shingles.
