This is the procedure that I believe that will accomplish my task (Please correct me if I am wrong):

1) remove ceiling joists and expose the attic (rafters). Both sides of the rafters are at 45 degree angles.

2) Insulate properly.

3) Drywall, tape and spackle.

4) Paint

I realize that I described it an a very simplistic manner (I know it will be much more dificult), but am I correct in the procedure?

Do I need to brace the exterior walls or rafters in any way?

Any and all comments or advice would be appreciated.

Thank you in advance,
Dom
