This is why I do all the roofing myself. And I put the screws in the ridge, not in the pan. The rib has enough room to put a screw flat on that little section. My work vs others. If its in the pan, I didn't do it. I can't put comments on every picture. And a picture showing where the water runs off. It was a video I took Clips out of. I didn't do the roof in the picture. But I replaced it, the right way.
