Support columns for second story roof deck
I have a walk out roof deck over my first floor bathroom and laundry room. I want to replace the three support columns that hold up the roof over the roof deck along with the rotted wood around the base of them. My question is whether to secure the bottom part of the column to my new floor or support the column below the floor near the floor joists and build the floor around the column when I redo it. If I put the floor(plywood sheets) in first then place the columns on the floor, how to I attach them without screwing or nailing into the roof so it doesn't leak into my first floor area? If I build around the column, I will have a gap around the column to seal off from leaks. Which is better?
