Abstract
EPDM or other roof membrane with preapplied seam tape is formed into a roll by forming two sheets and placing one on top of the other. The seam tape of the first sheet is at one end and facing one direction whereas the seam tape of the adjoining sheet is at the opposite side and facing the opposite direction, either up or down. The two sheets are then rolled up together. Since the combined thickness of the two sheets is constant throughout, the diameter of the roll is likewise constant throughout.
