I am installing some "pro rib" panels sold by a large home buiding company. Before I realized it I installed one side of the roof with the me panels with the outside "3/16 inch lip" ending up on the bottom instead of on top. Now I am wondering if it will more likely to leak? Do you have any advice? Thanks, Mark

I would swap the ribs so that the correct rib is on bottom. You should be able to do this by taking the fasteners next to the rib that is currently on top, out of each panel and lifing the rib of the bottom panel up, and to the top of the other rib. You may then need to add another fastener adjacent to this rib to ensure that it is properly fastened to the roof.
