No the foam is not completely waterproof. Once they get moisture in them your R-value is gone and it will never come back. There are many reasons they are not used here in the NW. One is better off adding rigid insulation under a real roof.

I agree but even thats gonna be quite costly. The cost of the ridgid insulation alone is pretty high. I have had a number of customers want it until we gave the a cost to do it. We just did one in Newport Beach about 2 months ago, but most folks do not want to pay that kind of $. Time consuming screwing it all down also.
