I would think that this would be between difficult and impossible given the way maps work. Even large scale - high resolution - maps tend to show buildings as mostly rectangles of one sort or another, detail of roof design is not the sort of data usually included.
You might well be able to get this sort of information out of Google Earth since it is a picture, but to get this level of detail you would be looking at a very small area which would not contain many roofs. It might be possible to write a program to do this but I think that would be a fairly daunting task: define area of interest (reasonably easy); define a 'roof' (?); measure each roof; list all greater than 50,000 sq.ft. (or 225 ft2 ). Your hardest part would be defining 'roof' in terms a program would understand.

Well...there are surveys/inspections of flat roofs within some areas...I would assume that such are costly.

I would be inclined to go along with R.A.D's suggestion - try a live body !
StreetView is a function of Google Earth and it definitely has its uses but you must remember that the camera was mounted perhaps 2.5m or 8-9 feet off the ground so looking up you are only going to see the edges of higher buildings which will not give roofing details. I suppose if you can't see the roof then it is probably a flat one . . . but !

It would pretty difficult to do from Google Maps even for a software. You can try putting a project specs in some of the freelancing websites and see if someone can make an app that can do this. Try Upwork. May someone will have a solution.

One possible idea to check is the county Auditor website. In my OH county at least, (and a very few others I have looked at) the property records show at least a rough diagram of buildings, including dimensions. I do think that telling if the roofs are flat or not is probably not discernible from this record though. Plus it would take looking up each property individually. Probably not a real solution but a thought.

Here is a report into what seems an interesting piece of research. It seems that the Ordnance Survey - the UK's Government mapping service - is currently researching ways of identifyng and classifying roof types from the mapping data they hold. It may not be of immediate relevance but does suggest that ways to solve the OP's problem are at least somewhere between here and the horizon. From 'The Register', 14th December 2017.
