Bill:
It appears to be just another name for it.
Commercial use of this name implies that a filter is low-pass with an upper 
cut-off freq.  (a roof)
But amateur usage seems to use the "roofing" name as being closer to the 
"front end" of the RX....
(a roof over the receiver??)

We had a discussion on this many months ago and we'll just adapt to the new 
interpretation...  :-)
