there is a lot more information that is needed before I could support the notion that it is the seams, humps as you are referring to.
What is the roof pitch?
Do you know what profile do you have? A picture will be helpful.
Often times leaks that come into a house start further up the roof.

We're told that rain is blowing up and into the humps in the metal roofing. (There's a leak only when it rains during a very windy storms.)
Is there a way to impede the water without blocking the roof from breathing?

Can you tell me a bit more about the installation? Is this open rafter construction and no formal ventilation?
