What is the square footage of the attic? The reason I'm asking is since you have such a small area to work with I would just add faced batts to the joist areas with no insulation, air sealing first of course. From the pictures it looks like your ceiling joists are spaced 24" on center and they are 2x6 joists correct? So what I would purchase is R-19, 22" wide faced for the ceiling joists, placed with the facing towards the living space below, and add an additional R-30 unfaced placed perpendicular to the ceiling joists on top of your current insulation. Add air baffles to the rafter bays to provide proper ventilation for the attic.
Thanks for the reply, handyman. The attic is pretty small - not sure about the sq. footage (the house is 1400 sq feet). I am not going to insulate the ceiling because it is being replaced this summer - and when my HOA replaces the roof, they REPLACE THE ROOF, from the plywood up! They strip it down to the joists and lay everything down brand-new.
