Thanks Forest. Looking at the end near the door it does indeed appear to cover a seam. Any way to coax it into sliding? It's a long piece, about 16' long but it won't budge. No way to really get a good grip on it either. I've tried a philiips screwdriver in the screw hold to try to provide something to actually push on but it doesn't budge a bit.

I have a sneaking suspicion that my leak is behind this guy. The lack of paint on one of the screws implies to me that at least 1 other person came to the same conclusion.
