   The link Mark provided is the only thing I could come up with - He just got it posted before I did.

   I have some published tables I could fax to you if you need 'em really bad.Common sense isn't very common.

   What I am missing, Boss, is the tables with the magic number of 60 psf snow on top.  The on-line calculator takes me up to 50 only.  If you have what I need on paper, tell me when you will fax, and I will make sure the line is clear: 518-523-7149

   You can try this calculator.

   Yes, I am serious.   And don't call me Shirley.

   I looked up your rafters on my Canadain Span Book.

   62.7 psf roof rafters ( no ceiling)

   2x10's  spf # 1&2 12" oc = 18'4

                                16" oc = 15'11

                                24" oc =13'

    Reply if you need different spans.  If you add collar ties you can increase the spans of rafters.
