What is the absolute best product for deflecting heat from a roof? So far, all I've found is Duration® Premium Cool Shingles at http://www.owenscorning.com/roofing/...-premium-cool/

Is this the best roof shingle product for deflecting heat from a roof?

And, what else can I do besides changing roof shingles and adding an attic fan to keep my attic/roof cool?
