That - and, in my experience (mainly with hybrid semiconductor devices), CTE-induced delamination tends to propagate from the edges. The very center of mass stays put, and the two materials progressively expand & contract more at increasing distances from the center. I'll be inspecting and imaging the roof every few days, so this theory may become apparent sooner rather than later, I'm afraid. Especially with volatile temperatures as winter subsides. I'm more or less reconciled to needing a new roof in the car's future.
