Amerimax 66004 4" x 50' Aluminum Roll Flashing - Durable Roofing Material for Home Repairs & Waterproofing Projects

i needed to try to cover a gap that i had between my roofline and a patio roof, as it would leak during heavy rains. I tucked this under my shingles adding about a 2" overhang. I put some construction adhesive about every 3 feet or so to hold it in place. This product worked perfectly for what i needed and was easy to work with and handle. Keep in mind this is pretty thin and can be cut with normal heavy duty scissors. If you need more stiffness then you will need a heavier guage flashing.
