You should probably visit a museum that has lot of different houses from different places, trying to conclude something from some houses you seen from the street is probably impossible. Houses in my village and region do not use metal and don't have windows, and windows on the roof is a good idea because you get a lot of light in the attic, it is a lot of effort to go in the attic to spy on someone if you can do it from a window from a regular wall anyway.
