One side done. What I did, was glue 1/16 rod to the roof at 1 1/2" intervals. When these were dry, I used contact cement on the roof and the back of the copper. 15 minutes later the cement was ready. I put a spacer between the copper and the roof, except the last 3 inches or so, so the whole thing wouldnt stick. Working right to left, I pressed down one section, then formed the ridge over the glued-on rod with a popsicle stick, and then moved the spacer. When that was done, I trimmed the edge, and rolled and glued the edges over.
