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.

Method of winding two overlapped sheets with preapplied seam tape

A method of rolling a membrane sheeting having a preapplied seam tape is disclosed. In order to provide a uniform diameter of the formed roll, filler strips are placed along the field portion of the membrane sheeting parallel to the seam tape. This is then rolled up to form a uniformly thick roll of membrane sheeting.
