Covered deck installation

After years of procrastination , I have finally decided to build a covered deck/porch off of the North side of our cabin overlooking our pond. The deck will run the entire length of the cabin North wall about 32' and extend about 10' from the cabin. The cabin side of the deck and new steel roof will be secured to the cabin wall with the outside of the deck and roof to be supported by 4 x 4 pressure treated posts.
I have discussed the building details with a builder that has been recommended a doing quality work at a reasonable price. He plans to bore a series of five holes to below the frost line and secure the 4 x 4 posts by setting the posts in the bored holes and pouring concrete to fill the holes and secure the posts. My concern is will the pressure treated posts eventually rot out at/below the ground level using this procedure and would I be better installing galvanized steel post anchors to secure the posts to the concrete rather than just sinking the posts in the concrete.
Also wondering if anyone could recommend an easy to install quality post base anchor bracket which I could use for this project.

Why not get cardboard concrete tubes and pour concrete footers that reach above ground. Then the wood could be replaced.

Simpson makes a 4x4 post base. BC40
Also they make a 4x4 to a 2 ply header BCS2 2/3

I use them on every screen room I build.

That's what all of ours are like.

Clarification because there is also a footer question.

The BC 40 is a post base that attaches to a deck.

In VA we dig a 16x16x20 footers pour 8” deep concrete and then set deck posts right on top.

Bill, Catscratch, Skelly, that's kind of what I had imagined doing but wasn't very clear in my description. Thanks for the reinforcement. I am still still looking for a good strong galvanized steel bracket that is easy to install, sets in wet concrete and secures the base of the 4 x 4 posts.

What Bill said,Sonotubes(sp?) work well. Keeps the heaving ground from "grabbing" the concrete.

I have used the attached when using Sonotube (cardboard form) allows you to install anchor but still allow your 4x4 to seat in the base.

Skelly, does this bracket include an anchor for installing in wet concrete when poured or are you required to wait until the concrete dries and then drill the hardened concrete to install a fastener?

Drill afterwards.

Way easier to install after footers are poured and can lay out the post location.

Post base does not include fastener.

Putting posts in the ground with cement on them would be fine for a fence, with with the roof load you really need a cement foundation footer below the post.

If you get snow, even more load.

Go with 8"x8" treated, they will out live you and the next generation.

I’ve learned from experience two things, The concrete base is the way to go with the tubes and brackets. Also, use at least 6 X 6 posts. 4 X 4 tend to warp too much. Even 4 X 6 warp. 6 X 6. Is way to go
