  • Patent number: 12753608
    Abstract: A method for connecting an edge metal flashing to a roofing membrane, the method including the steps of: providing a roof assembly including a roof substrate, an edge metal flashing, and a roofing membrane, wherein a portion of the roofing membrane is trapped between the flashing and substrate and wherein the membrane is a water impermeable liquid applied membrane; applying a reactive adhesive layer to a portion of an upper major surface of the flashing; applying an epoxy resin layer on top of the reactive adhesive layer; and applying a water impermeable liquid applied membrane on top of the epoxy resin layer so that the applied water impermeable liquid applied membrane also covers a part of the water impermeable liquid applied membrane. The method provides an edge metal flashing connection system which is easy to apply and provides the required long-term watertightness.

  • Publication number: 20260035925
    Abstract: A method for sealing adjacent roofing membranes of a hybrid roofing assembly. The method involves applying a sealing strip to establish a connection between the adjacent roofing membranes and creating a durable water tight seal at a joint between the adjacent roofing membranes, using a water impermeable liquid applied membrane. The method enables connecting in a water-tight fashion two incompatible roofing membranes using a water impermeable liquid applied membrane, thereby enabling the creation of hybrid roofs and reducing both repair and installation expenses.
