A lack of understanding is also shown in the FT-2000 Yahoo! group. A fine
document which explains traditional roofing filters is here:
http://www.qth.com/inrad/roofing-filters.pdf . The FT-2000 is an
up-conversion receiver (unless I've lost the plot again).
Elecraft's design is more subtle and has been explained several times in
this list.

Roofing filters - I think the term has more to do with marketing than
engineering. Other companies have made a big deal over having them and
people have come to think of them as something special.
