I'm looking beam solution ' span. it will

Customer Question

Hello I'm looking for a beam solution for 28' span. it will support floor joists and roof load (holding up second floor)
JA: OK. Tell me a bit more about what's going on so we can help you best.
Customer: the total joist length will be ~20'
JA: Is there anything else the Structural Engineer should be aware of?
Customer: I want the beam and joists to be flush, so joists hanging on beam not sitting on beam.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Structural Engineer about your situation and then connect you two.

I can help. Can I get back with you on a few hours when I get home from work?
Customer: replied 1 year ago.
Yes that would be great. I should also add the following - Can I use 2x4's for the columns instead of steel posts? Will the existing conc. block foundation have any issues with the point load of the columns? Also I want to cantilever it off the front, but I assume a beam that can take the 28' load should be just fine with a 4' cantilever. Last - If I need to I do have a wall about midway I could put in another column, but then I have to put something in the basement under it.

I do have some rough draft drawings if that will help as well. Talk to you in a few hours.

Can you take a look at the following link and answer the questions at the bottom of the sheet? Your answers will allow me to accurately model the loading and size your beam. Thanks

1- This would be new Beam #4, 2 - joist span is 20', 3 - I'm planning trusses, 4 - I'm in Michigan, so yes snow load, 5 - roofing will be asphalt shingles.
