The driving issue in this case is not keeping the panel down but preventing it from blowing off in a strong wind.
Roof panel clips.
Keeps panels even for a level structural plane.
Panel sheathing clips are used to brace unsupported panel edges when sheathing meets edge to edge without a rafter for support.
Therefore a structural engineer or other design.
The clips are inserted over the edges of the adjacent plywood panels to reduce deflection of the panel edges between the framing members and are most commonly used for roof sheathing.

This is what the apa engineered wood construction guide has to say about h clips.
Our design and engineering input has been instrumental in producing some of the finest economy and heavy structural clip screws in the industry.
And our bearing plate design has set a new standard overall.
A low slope roof below 2 12 pitch at the same span is an exception however and an h clip is specified.
Quick installation no nails required.
H clips are also necessary for other wood panel thickness and span combinations.
The panel clips connect the roof panels to the roof structure so they need to be installed in a manner that allows them to do that job under normal and demanding circumstances.
One or two h clips will often allow a longer span between roof trusses rafters.
We precision stamp snap lock clips of all types for architectural structural and many other varieties of standing seam roof panels.
