Abstract
A roof system includes a roof deck including a rake edge, an underlayment, a plurality of asphalt shingles, and a one-piece metal apparatus. The one-piece metal apparatus includes a stem, an upper arm, and a lower arm that form an F-shape. The upper arm and lower arm of the one-piece metal apparatus are above the underlayment, and the stem is situated outside and adjacent to the rake edge of the roof deck. The stem, the upper arm, and the lower arm form a three-sided space to accept a thickness of the overlapping rows of the plurality of asphalt shingles. The end of the overlapping rows of the plurality of asphalt shingles are situated within the space formed by the stem, the upper arm, and the lower arm of the one-piece metal apparatus.
