My house is 2000 sq. ft. and has trusses with an 8-pitch roof. With that roof pitch, I could have a huge attic-upstairs if not for all the braces that go along with the trusses. Is there any was a truss system can be rebuilt to a normal attic space without tearing them off. Could I put down 2 by 10 floor joists beside the existing truss joists and put 2 by 6 rafters along side the existing rafters and gradually remove the truss braces as I construct the regular brace system?
