摘要	Shingle blanks including a first fold region, a second fold region, a third region, a lower edge and an upper edge are provided. The shingle blank has a length. The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.
