This plywood in the roof has a hump in it.  This is due to the buildings height and the fact that there can be movement and rafters. The Locations that are heaving and bowing appear to be strong And not vulnerable to leak immediately. Bowing and rotting plywood is excluded in service agreements but they should be monitored for any possible issues in the future.

There were approximately 12 to 15 locations that had the same Bowing affect going on on the roof.
