I'm about to install 36" panels. They are overlaping panels with 3/4" ribs every 9" with leser ribs between. I'm concerned about the valley flashings for the dormers and have been looking for a good photo or illustration of a valley dumping onto another panel. I found a photo on this site but it was of a standing seam installation. I know that the valley must terminate above and onto the other panels but I'm not sure how to achieve it. The valleys are of the W type. Also: It would be great to find an illustration for intersection of the two valleys above the dormer. Thank you!

The pictures of the dead valleys you saw on this site were probably mine. A through-fastened roof would work the same way. You may wind up with a panel rib in the way where the valley terminates. If this happens, you can get a curb comapny to make you a rib cover that will seal off the open end of the rib of the lower panel. The rib cover will need to have a base that is long enough to extend up, under the the end of the valley flashing. Attached is a picture of one for a standing seam roof.

Here is a picture of the two valleys mitered together at the ridge of a dormer.
