I had a larger roof built over my old deck. New 6x6's were used to support the new roof. They set on cement filled 8" tubes set 40 to 46 inches into the ground. I have been told I have to use 2x8 beams and 2x6 as floor joists. This will bring my floor height with the added decking to my desired height.
I am told I have to notch the support posts. If this is done, I will be doing this at the top of the cement. Is this acceptable, or is it better to pour a cement slab for the porch? After this is done, I want to make it a 3 season room.
