A surface mounted counter flashing system and method is provided for securing and sealing a free end of a roofing material to a wall. A compression plate secures and compressingly seals the free end of a roofing material against the wall surface. The top end of the compression plate defines a first sealing trough for receiving a sealing material. The bottom end of the compression plate includes locking portion for attachment to a counter flashing. The counter flashing includes a mounting surface which is mounted to the wall above compression plate. A covering surface extends out from the mounting surface and encloses the compression plate protecting it from exposure to weather. A locking member is provided on the covering surface which connects and attaches to the compression plate, thus, securing the counter flashing. The top end of the counter flashing defines a second sealing trough for receiving the sealing material. Adjacent counter flashings are installed end-to-end leaving a gap therebetween. A splice plate is attached to the adjacent counter flashings at the second sealing trough and covers the gap. The gap and splice plate allow for movement of the counter flashings. The present invention provides for easy assembly and disassembly of the components and provides for a long lasting seal.

DETAILED DESCRIPTION In accordance with the present invention, a surface mount counter flashing system is provided for sealing a roofing material to a wall surface.
The system includes a compression plate which attaches to the wall surface and compressingly seals the roofing material against the wall surface.
A counter flashing includes an attaching surface which attaches to the wall.
A free surface extends out from the attaching surface and encloses the compression plate to restrict exposure of the compression plate to weather.
The free surface connects to the compression plate to secure the free surface of the counter flashing.
In accordance with a more limited aspect of the present invention, a second counter flashing is attached to the wall adjacent and end-to-end with the counter flashing such that a gap is defined therebetween.
A splice plate is attached to both adjacent counter flashings and covers the gap.
In accordance with a more limited aspect of the present invention, the compression plate provides a first sealing trough filled with a sealing material and the counter flashing provides a second sealing trough filled with a sealing material.
The two sealing troughs provide double protection to prevent fluid from leaking between the roofing material and the wall.
In accordance with another aspect of the present invention, a process for securing and sealing a free end of a roofing material to a wall is provided.
The free end of the roofing material is compressingly sealed against the wall by a compression plate where the compression plate includes a first edge and a locking edge.
The first edge defines a first trough between the wall.
The first trough is filled with a sealing material.
A counter flashing is provided which has a mounting surface and a covering surface extending thererfrom.
The mounting surface of the counter flashing is attached to the wall above the compression plate such that the covering surface encloses the compression plate.
The mounting surface includes a lip extending out therefrom which defines a second trough between the wall
