I am a home inspector that just reviewed a standing seam metal roof for a friend of mine. The roof is a new installation, but is leaking badly. I can clearly see that the flashing details are improper, but the roof is also leaking at or near the ridge in several locations. I checked the manufactureres website (Wheeling Pittsburg) but they had no installation details. Where can I find the proper crimping, pan width, fasteneriner spacing, guage recommendations, etc. in order to establish if the roof is installed properly?

I would call the manufacturer and have the detail faxed or mailed to you. Generally speaking the details are included in an overall manual that is very large and not generally posted on the site.
Make sure you have a residential product and check the various building product approval reports. ICBO, DADE, SBCCI etc. They typically have the details in it.

After reaching the manufacturer I was informned that they do not sell this material as roofing, rather for HVAC duct fabrication. Is 29 gauge galvanized HVAC duct sheeting suitable for standing seam residential work if the manufacturer doesn't recommend it for that application? Also, do you know of an open source for typical standing seam installation details?

The thickness of the steel is not of primary importance but the metalic coating weight is. A minimum of G90 for painted galvanized steel and AZ50 for Galvalume exposed is recommended.
I do not believe that the product you are looking at is Standing Seam as it is typically not formed from 29 gage material. It sounds like you may have a vertical rib panel that is through fastened. Depending on where the material was purchased, it may have been an agricultural panel formed from lower weight steel.
HVAC duck work is typically steel rejected from the roofing and siding industry. Did you contact the company that made the steel or the one that roll formed it into roofing.
One should always contact a member manufacturer of our asociation and specify that you want a residential metal roof system as they will ensure it complies to the MCA guidelines.
Hope this helps.
