Interesting - I hadn't really thought about it from this point of view but
you are right. I often tear back and rebuild my stuff multi times to get it
right and the overlapping causes a lot of extra tearback. I did build one
model in this modular way (the Schoolhouse,
http://www.lionsgatemodels.com/cat-schl.htm ) because it had colored stacks
of bricks at the corners, and it was quite convenient to be able to remove
the front or back walls, switch them over, or leave them off completely for
interior viewing at shows. The corner columns of 1x1 bricks weren't very
stable though :-)

A cheaper way to reinforce the underside is to use a row of plates along the
underneath of each row of roof slopes where they don't overlap the next row.
It doesn't look as good but it adds considerably to the strength.
