Hot Roof with Standing Seam Metal Roof – Is this a problem? – GreenBuildingAdvisor

I’m in the process of building a house in a high fire zone (California SF Bay Area).  In order to achieve this the goal is to remove all soffit vents and use a metal roof.

Since I lack soffit vents, I was planning on doing a hot roof, with 2″ of spray foam, followed by non-faced batt insulation.  The spray foam was to avoid condensation build-up, and the non-faced insulation (probably rockwool) was to help with both noise and to ensure we had some interior drying potential.

The roof material is PacClad with Pac-Clad HT underlayment.  Roof is already on, and about to do insulation.

The Pac-Clad HT is not vapor permeable (0.02).

Architect also wants to spray-foam and enclose all eves.

Given all of this, am I setting myself up for issue in the future, in the case any water gets between the roofing and the sprayfoam?  If this is an issue what are my options to mitigate?
