Personally I always try and align building footprints with the base 
rather than the roof (otherwise very tall buildings would look very odd 
indeed).

I can see why (if you were mapping lots of small buildings in e.g. a HOT 
response) it would be easier to say "just trace the roofs" - it'd get 
more buildings traced quickly at a good enough quality (which surely is 
the aim there), but as a general principle where time isn't an issue I'd 
certainly try and trace the building footprint.

Cheers,

Andy
