Decaf is a little tricky, compared to regular, but not really hard to
roast. Typically it takes a little less roast time than regular and it
shows oil on the surface of the beans at lower roast levels than
regular coffee.  It has little or no chaff released during the roast,
so if your roaster is one which expects to collect chaff to help keep
the air flow down and temperature up, then it could change the
expected temp profile compared to regular coffee.
It still has the first and second cracks, and it still makes smoke as it roasts.
If all you ever will roast is decaf, then once you have the hang of
it, you'll be fine.
Get you some decaf greens and give it a shot.  On your first roast,
take it all the way into french or more (keep going past the first
cracks, the gap between first and second and on well into a rolling
second crack) just to get a feel for how it sounds and smells. Second
crack has a distinctly different sound than first crack. Learn to hear
it. First cracks are closer to sharp pops; second cracks are quieter
and more "crackly" sounding.
Get  a stopwatch and note the times when first crack starts, ends, how
long the gap is, where second crack starts and where you end up.  This
will give you some benchmark times to keep an eye on in future roasts.
 You usually don't want to roast purely by time, but it is helpful to
have an idea.
Then go back and run another batch and see if you can stop it between
first and second cracks (CITY to CITY+). Wait a day and brew it. (Oh,
you'll go ahead and brew some almost immediately... we all did that...
 but just know that it will actually be better the next day, even
though the cup you just brewed was likely the best you'd tasted in
your life).
If you decide to roast some regular, it normally takes about 20%
longer than decaf.

I've found decaf outgases sufficiently to taste delicious after 4  
hrs. of roasting and begins to peak at 12-24 hrs. Delayed  
gratification is definitely unnecessary.

Sandy,
You are certainly the decaf queen!  I agree that decaf usually needs
less rest than regular.  (I wonder if the same changes due to the
decaf processing that make it show oil at a lighter roast level also
makes the out-gas event happen faster?)
We don't usually brew straight decaf, but our morning drip pot lend is
20 gr decaf + 25 gr regular to make 9 "cups". When we have brewed
straight decaf, the homeroasted decaf is so good that I know I could
switch to all decaf if I ever needed to do so.

Thank you ... I really do appreciate the insight.  I
just ordered a bunch of greens (some regular and decaf
of the same, and others) and can't wait to get
crackin'!

Folks,
Thanks for the help with roasting the Decaf.  I
roasted some this weekend and just had my wife try
some of it without telling her it was decaf.  Her
response was, "OOOOH, this is Camille coffee."  Then I
told her it was decaf.  She just left the house with
the Thermos to share with mother and sisters.  I must
say that I enjoyed it as well.
Thanks again!
Eddie

Many thanks to you folks!  So far I have given home
roasted decaf coffee to four people that nearly fell
on the floor when I told them afterwards that it was
decaf.  Three of them were drinking it black!
Thank You!
