Selecting Nested Polygons using ArcPy

First, is there a way to select nested polygons that are completely surrounded by a larger polygon? For example, I'm working with polygons that represent roofs of buildings, and in some cases, there are multiple polygons for a roof, especially when there is a taller  structure in the center of the roof, surrounded by a lower roof area.

Second, would it be possible to automate selection of these nested polygons and tie them to their larger, parent polygon, that completely surrounds them?

I need to combine multiple roof polygons to form one "building" polygon.
