The big heat wave is over and were back to low 80's
The Shasta white shingle have Owens Corning highest solar reflective index, or tied for #1.
The Prior roof was dark and non reflective.
The difference is dramatic.
On an 82 degree day in the upstairs is now only 1-2 degrees hotter than the downstairs vs 8-10 or more. The attic never triggered the 105 start on the attic fan.
Impressed so far.
