Laying Out Rubberall EPDM Membrane
Unroll the EPDM membrane over the substrate so that the sheet is in the desired position and is wrinkle free. If more than one sheet of membrane is required always place the first sheet of membrane at the low point on the roof. Subsequent sheets would overlap the prior sheet by at least 10.16cms if using seam tape or 15.24cms if using rubber to rubber adhesive, moving up the roof. Care should be taken to ensure membrane overhangs perimeter of the roof at least 7.62cms.
