Can construction foot traffic on the roof dislodge or break the seal between the foam and the sheathing?

I am having the underside of my roof (flat roof-1/4″/12) sheathing sprayed with 2″ of closed cell foam (flash/batt). I am concerned that construction foot traffic on the roof will dislodge or break the seal between the foam and the sheathing. There is quite a bit of flex in the roof sheathing. Is my concern valid?

If the underside of the sheathing was clean when the foam was applied an it was applied under the appropriate temperature conditions it's not coming off without a chisel. (It's chemically similar to Gorilla Glue.)
