ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is directed to the roofing arts. It finds particular application to a counter flashing system and method that seals roofing material. It is to be appreciated that the present invention also finds application to other roof and wall sealing systems which may include reglets, flashings, and/or coping structures.
Reglet, flashing, and counter flashing devices have been used to form water-tight seals and covers for joints or termination areas of different wall materials of roofs. Many of these prior art devices have been found to be difficult to assemble and install, and have been unsatisfactory in installations covering the termination of a water-proof roofing membrane extending along a portion of the wall. Once installed, many prior art reglet, flashing and counter flashing assemblies are very difficult to replace often requiring the components to be ripped out and re-installed. In addition, longitudinally adjacent sections of these devices have been difficult to properly align, thus, presenting the possibility of leaks at adjoining section joints. This makes a precise installation difficult and expensive to achieve. Additionally, installation forces exerted on the components of some prior art reglet or flashing structures cause the components to rotate or be pulled. As a result, sealants may pull away from the wall and/or break between adjoining sections causing adverse effects to the water-proofing performance of the wall membranes.
The present invention provides a new and unique counter flashing system and method which cures the above problems and others.
SUMMARY OF THE INVENTION
In accordance with the present invention, a roof counter flashing for attachment to a wall is provided. An anchor has a first end which attaches to a wall and a second end which has a slot. The slot includes a plurality of teeth. A counter flashing has a mounting end and a free end where the mounting end is removably mounted within the slot of the anchor and has a plurality of teeth that engage the plurality of teeth in the slot. A fastener maintains the mounting end of the counter flashing in engagement with the slot of the anchor to secure the counter flashing to the anchor.
In accordance with a more limited aspect of the present invention, the first end of the anchor is mounted within the wall.
In accordance with a more limited aspect of the present invention, the anchor includes a ledge which receives and holds stucco material.
In accordance with yet a more limited aspect of the present invention, the anchor further includes an edge extending out from the anchor between the first end and the second end which defines a channel for receiving a sealant.
In accordance with a more limited aspect of the present invention, a splice plate snap connects to the edge of the anchor and attaches to the free end of the counter flashing and covers a portion of the counter flashing and anchor.
In accordance with another aspect of the present invention, a counter flashing system is provided. An anchor means includes a securing means for securing the anchor means to a wall. The anchor means includes a mounting means for mounting a counter flashing and includes a grip means. A counter flashing which covers a portion of a wall is removably mounted to the mounting means by engaging the grip means. The grip means reduces the movement of the counter flashing.
In accordance with a more limited aspect of the present invention, the grip means includes at least one projection which engages the counter flashing.
In accordance with a more limited aspect of the present invention, the counter flashing includes at least one projection which abuts with at least one projection of the grip means.
In accordance with a more limited aspect of the present invention, the mounting means includes a slot which receives a portion of the counter flashing for mounting.
One advantage of the present invention is that the counter flashing is detachable from the anchor without having to damage any of the components.
Another advantage of the present invention is that the anchor grips the counter flashing with a plurality of teeth which prohibit the counter flashing from moving or disconnecting from the anchor.
Another advantage of the present invention is that the components quickly and easily connect and disconnect to one another simplifying installation and removal of the system.
Another advantage of the present invention is that the termination bar is enclosed by the counter flashing protecting it from weather and ultraviolet rays which extends the life and functionality of the termination bar and its roof seal.
Still further advantages of the present invention will become apparent to those of ordinary skill in the art upon reading and understanding the following detailed description of the preferred embodiments.
