When it comes to home inspections we can never loose site of what the intension is...It is meant for the seller to cure specific defects related to contract verbiage.  Many times it becomes a honey-do maintenance check list and buyers and sellers loose site of the intent.  If there are any concerns regarding items relating to home inspection it also goes back to the way the contract is written.  If a professional is required to determine the extent of the problem in question, then that is the professional that needs to take a look.  Is this roof not functioning?, evidence of leaking?  I see it has been patched, but what is the intension?   That is determined by what the professionals say....
