I am making a 14×16 open carport this weekend.
Is there any way possible for me to avoid digging and setting the posts with concrete? I am going to be using 4×4 posts. I don't know much about construction so i cannot figure it out.
I basically live on one big boulder so digging isn't the most feasible idea.
We do get a heavy snow-load but my roof is going to be steeply angled to one side to cover that.

Either you dig to set metal post anchors or you dig to set the post's. Also, since your in a climate that has freezing weather, if you want to build by Code, you'll need to dig your holes 48" to avoid ground heave from frozen soil. So the only real decision than is what is more secure: metal anchors or posts set in concrete? Post's will give the greatest support if set in concrete. I believe a 1/3rd of the total post length is recommended to be set in the ground. You should also use treated or naturally decay resistant (cedar, redwood, cypress) posts if set below ground level. You could also use concrete piers, but the footing will still need to be below ground freeze (48 inches).
