Abstract: A reinforced elastomeric membrane installed over a new, or existing, non-reinforced waterproof elastomeric membrane of a roof covering and the method of installing the reinforced elastomeric membrane in a continuous and watertight condition that will offer more continuous puncture resistance than current art. The overlapped edge portions of the two membranes (i.e. the new or existing EPDM membrane and the new reinforced EPDM membrane) are sealed together by an intervening adhesive layer. Using reinforced EPDM as walkways to, around, and between serviceable roof top curb units, roof hatches, and roof access points, on new or existing non-reinforced EPDM roofs, provides a greater degree of continuous protection than current art.
