I hired a contractor in insulate my roof deck with open cell foam. My rafters are nominal 10-bys and the contract says 8"-9" subject to variations. The picture below shows what I'm finding so far (they are coming back in two days to finish another part of the house). Is that simply the first of two layers? Or am I in trouble with a potentially dishonest contractor? I hope the former!

Many thanks in advance!
