Abstract: A nonpenetrating roof membrane fastening system for covering and securing a waterproof flexible membrane on a roof deck. A plurality of flexible spot bonding pads are secured at spaced intervals to the roof by a smaller, more rigid, fastener plate or washer and a linear fastener which extends through the aligned centers of the pads and plates. An outer exposed peripheral area of each of the bonding pads has an adhesive applied thereto and bonds the pads to the underside surface of the flexible membrane which is laid over the secured pads avoiding any penetration of the membrane by the linear fastener. The membrane is a nonreinforced EPDM and the bonding pads are formed of a fabric reinforced EPDM.
