2x10 joist 16 OC that span 10 feet in one direction and 9 feet in the opposite direction. Roof pitch is a 4 and 12 with one layer of asphalt shingles. Perkins come off of rafters ever 6 feet at a 30 degree angle and intersect the double top plate of the load bearing wall. Customer would like to remove entire load bearing wall pause a 4x10 douglas fir beam spanning an additional 9 feet and put in a steel I beam to span the entire 20 feet.

Hello

Will it support a second floor, attic, and roof? Or just attic and roof? What is the city and state so I can look at snow loading?

Just floor joist and ridge beam. Ventura California.

No

You can plan for a W10x33 beam ASTM A992 Gr. 50. It's 10" deep X 8" wide and weighs 33 pounds per foot. This will require detailing the joist connection to the beam to resist lateral torsional buckling.
