Here's the saddle area, dismantled. We've installed " fascia/roof juncture flashings" uon either side up to the flat. Then we've installed 2 wide sections of galvanized steel to provide a spilloff area. What we did then to finish, was install a granulated self-adhering modified membrane to the "spilloff" sections, and up under the pitched areas a minmum of 1.5-2ft. Then shingled to finish repair.
