Palomino Bronco Roof Dip Edge

It was a while ago, all my old photos are on a iphone somewhere... i just took a piece of rigid aluminum, bent it 90 degrees (the front was somewhat harder as it came in at an angle ) around that corner and bolted it into the front and side where there was good wood. I used eternabond tape to waterproof it underneath too. If i recall correctly, I actually sistered the rotten wood with a good piece of 3/4 Pressure treated decking to get good enough wood to bolt through. Those tops are junk, and so hard to repair! Good luck! Also, there was some sort of adhesive between the osb and the drip edge. I remember using a small wire wheel on my drill to remove it.
