First, I needed to center the plywood on the roof. I am not sure how well this will show up, however, I found the center of the roof, as well as the center of the plywood I was putting down.
The bottom arrow shows a pencil mark on the roof, 2 feet to the passenger side of center.
The top arrow shows the center of the bottom plywood and the center of the top plywood.
This is the rear of the roof, showing the center of the new plywood and the center of the current roof.
Putting pencil marks all around the plywood on the roof, gave me a reference point for when I put down the new plywood, as well as where to put the adhesive.
