Roofing inspections on tall buildings

[Todd Kozak]

I recently went under contract with a house that has 3 stories (2-story with large attic).  There isn't access to the roof from the 2nd or 3rd story.   They only have 30' ladders and that wouldn't work.   They didn't inspect the roof.   Should I expect them to?  They gave me a contact to a company that uses a drone.   That costs $175.    Should I expect the inspector to cover somE of those costs?  What is your experience with roof inspections on 3-story buildings? 
thanks!
