How would you determine the roof deck attachment with dimensional lumber on top of the trusses and plywood on top of the lumber? The plywood thickness could not be determined because of the spacing of the lumber blocked all access to measure the plywood. However, minimum 6" nail spacing on edge and 6" in field could be determined.
Typically they use half inch plywood. If you look around you can usually find a place to measure it. I’m in your area if you want give me a call.
Check for roof penetrations, may be able to see both layers.
Woody, you do carry an 18 volt cordless recip saw, right?
That sounds like a ‘HOLMES’ Inspection to me. LOL
