What are the advantage and disadvantage of insulating or attaching R-22 insulation to the underside of the roof in the attic? My house is located in Dallas, Texas.

If you have 2X6 rafters, there should be no problem, other than finding R-22 insulation. What you will find is R-19, for a 2X6, or R-25 for a 2X8. Don't compress fiberglass insulation -- that will reduce it's effectiveness.
