When my son bought his house there was 0 insulation in the attic. He found that out when he got his first winter heat bill of $650. The next spring I drove to Menards and bought their cellulose insulation which was almost a 1/3 the cost of buying local. Rented the blower machine from the local Home Depot and two days later his attic was R60. There was enough insulation left to do my garage 24" deep. Go big or go home.

No idea about the paint, but how can it reflect heat out from under the shingles and roof material?
