i recently had 2900 sf of standing seam metal roof installed on a new home i am building and GC'ing it myself. i paid for the material directly and used a installing contractor that was recomended by a construction aquaintance. about half the roof is 1.5:12 and the other half is 2.5:12. the contractor told me that ice and water shield is only required at the low eaves 3 ft up. the rest of the roofs are installed directly on the 3/4" plywood. we are also using closed cell spray foam insulation. we were told that we do not need venting in the soffits with spray foam. i am concerned with the installation. the skylight and chimney had leaked and they are in the flatter roof. aslo there appears to be a lot of moisture in the plywood in the flatter roofs. we are currently roughing in plumbing and HVAC and i am about a month away from spray foam. after the 2 leaks i researched the manufactures installation instructions and the 2 curb penetrations were not installed per manufactures details. at that point i discovered the manufacture recomends a minimum pitch of 2 and it could be designed flatter with the use of ice and water shield. my question is, is the roof ok installed directly on plywood and do i have any recourse with the installing contractor? we elected not to pay for manufactures shop drawings because they were $5000 and the roof is basicall 4 different rectangls with no valles

In my opinion there should have been underlayment. Yes, the panels probably can be removed and re-installed. Check with Kingspan.
