I agree about concerns on how the velcro will work. I may use some  
thin battens to spring a curve on the insulation, and some edge strips  
on pop top to hold the insulation in place around the edges and hope  
the velcro will work holding the battens in place in the middle.

And yes, wonder about any moisture trapping spaces between roof and  
insulation. Having it removable is a compromise made to facilitate  
cleaning.

Its all undiscovered country for me Chris, sort of making up as I go  
along.
