Patent ID: 11118357

Abstract:
Flashing for use at the edge of roofs or decks that are provided with surface materials are presented. In exemplary embodiments, flashing may be provided at the edge of a roof to retain or provide an edge treatment for an aesthetic and functional surface material, such as, for example, a cast paver, while at the same time allowing for water drainage. In one embodiment, a piece of flashing material contains a leg that is fastened along the edge of the top of a flat roof. This embodiment continues into two legs that form a V-shaped trough which comes off the roofing membrane and has penetrations at the bottom to release water. The outer leg of the “V” most commonly extends to a level higher than the roofing membrane in order to make contact with and edge an installed surface material. Various other shapes and end treatments, including various embodiments providing both an edge flashing as well as an integrated rectangular shaped gutter-like trough are also presented.
