Waterproof deck flashing system and method

摘要

A two-component deck flashing system and method for installing the same. The system utilizes “L” flashing strips with attached cleats utilizing clinch lock joints to alleviate the need for fasteners which might otherwise penetrate and easily damage waterproof sheeting materials. A cover plate is attached to the cleats to define the outside edge of the topping surface. This two component system is designed for installation at wall-to-deck junctures by incorporating a form of a wall “saddle” flashing having one or more wall plates with attached “L” flashing extension with cleats and cover plate extensions. All components are integrated with and overlapping adjacently installed components to provide a flush, easily sealed and maintained, top surface. This two-component deck flashing system can be installed more easily and effectively in the field than prior art systems.

主权项

1. A waterproof deck flashing system for mounting on a free edge of a deck allowing water collecting on the deck to run off the free edge without seeping into materials upon which the system is mounted comprising:
one or more “L” flashing strips extending longitudinally along the free edge of the deck and having a horizontal leg extending horizontally over a horizontal surface of the deck at the free edge and a vertical leg extending downward from the free edge of the deck; one or more cleats attached with the one or more “L” flashing strips, said one or more cleats
having a width less than the longitudinal length of the one or more “L” flashing strips such that a plurality of the cleats may be attached along the longitudinal length of the one or more “L” flashing strips and allow water to flow between the cleats and over the free edge, andhaving a horizontal leg for attachment with the horizontal leg of the one or more “L” flashing strips and a vertical leg extending above and away from the free edge of the deck,wherein the horizontal leg of the one or more cleats is attachable to the horizontal leg of the one or more “L” flashing strips without penetrating the horizontal leg of the one or more “L” flashing strips or any waterproof sheet or other waterproofing materials that might otherwise be mounted on top of the horizontal leg of the one or more “L” flashing strips; a waterproof sheet for mounting on the horizontal surface of the deck and extending over the horizontal leg of the one or more “L” flashing strips; a drainage sheet for mounting over the waterproof sheet; and one or more cover plates which, when attached with the one or more cleats, extend vertically above the free edge of the deck to form the outside edge of any topping material that may be applied over the drainage sheet.
