removing some ceiling joists & double remainders to create open beam ceiling
4/12 roof single story. Putting in Liv. rm only. doubling every 4th joist & maybe make an open coffered ceiling. Putting foam and sheetrock on rafters. I live in So. Louisiana, but have woods between house and south side of house. House did not flood in Katrina.
Easy - consult a structural engineer - any other advise or just winging it is just asking for trouble especially with so much information that is missing
