I have built two "shed roof" carports using 4 x 4s for supports. I also
used 6 posts per bay. The first one was a 3 bay, the second one was a 4
bay. On the second one I put each post at least 3 to 4 feet down and put
at least 3 sacks of concrete on each post. I also put diagonal wind
bracing in both directions. Roofing on both is galvanized ribbed steel, no
sheathing, although I did nail 1 x 4 strips about 16" or so on center
across the rafters. No problems. The first one had almost 2 feet of wet
snow on it once.
I have a full set of pictures I can send out on CD if anyone is interested,
or if anyone wants to post on a web site.
