I have a metal roof about 10 years old the ends where a flat roof begins. I had my flat roof replaced with a tpo system. It leaks much more than ever before. I am being told that water is getting under the ridge cap and in the screw holes and that is where the water is coming from. Under the ridge cap there is no foam. Under the metal roof is the old composition roof. I am being told to replace all of the screws and seal under the ridge cap. I do have a low pitch roof. I just don't see how that much water can get under the ridge cap. No water is getting in the house. And the attic is dry. What should I do?

Did the leak start after the TPO roof was installed? How did they tie the two roofs together?

It had developed a leak in the tar roof. I had the tar roof removed and the tpo roof replacing the tar. I thought the tpo was put on top about 10" overlapping the metal roof. But they put window flashing on the metal part and the tpo at the edge . It leaks more now than before. I was told the tpo should have been put below

yes, the TPO should be under the metal roof.

+1 Big red flag there. I am sure the membrane guys didn't want to mess with the metal, but you must, must, must run the membrane under the metal in this case.
