? About cool roof shingles and Low-E Therma Sheet

[Jared Cooper]

I have a small rental in the East Valley that I need to replace the shingle roof. I would like to reduce the amount of heat transfer into the attic and house, reducing cooling costs. I was given information on a product called Low-E Therma barrier that can be applied to the sheathing and then I’m considering the shingles by GAF or Malarkey with “cooling” granules? Also, will blow in more insulation into the attic. 

Has anyone used either the Low-E and/or cooling granule shingles? Reviews? Any recommendations on the most cost effective strategies for roofing in the Valley? 

Thanks!
