Additionally, there is a difference between the roof membrane and the roof structure. The leaking results from some problem with the membrane. It is either partially gone or a seam has been opened. I would guess that a seam has opened at the perimeter and the wind drives the water inside.

There is more wrong with the roof than a leaky membrane. I'm seeing daylight on NBC and BW is estimating holes 3'x 5'.
