Bingo ^^^ , did you tear down that old wood entry ? If you want to get real detailed cut 2 strips of roofing copper 1 just cut to stand and follow the contours of the ribs and the other put a 90 the full length about an inch and then cut at the bends needed to lay flat then solder the flat vertical in front of the 90 bend , thats the old fashioned way that lasts ,install with the flat vert piece behind the siding if possible or at least back from what little roof overhang you have , then caulk with black jack or some other butyl based roofing sealant .
