Roof Seam

[fred]

I have a 2012 avalanche while working on roof doing some caulking noticed about a 6 inch piece of the plywood was popping up at the seam in middle of roof.Can not see it unless you walk on it or sit on it.It is where roof starts to curve down toward front cap.Is this something i should worry about or just keep eye on it. I have some 4 inch enterbond tape was going to run it along seam just for some extra strength.Any suggestions? Thank You

If it were me, I would leave it alone and inspect it on a regular basis. If the plywood is not secured to the frame, adding eternabond isn't going to do much to correct it.

Since the roof membrane and tape aren't rigid, IMO your making a possible future repair if needed, much more difficult.
