    yes it is a great product and well worth the investment. i used insulation from buyfoilinsulation.com

    No dont add to the roof. The under side of the roof needs air flow and you will trap moisture, causing mold and rot. Make sure you have plenty of vents under your eaves and take your extra money and buy a solar powered attic fan (or 2 )

    do not insulate your roof,it will cause the roof to get VERY hot,this will damage the roofing,shorten its life,,the temp in your attic should be within 3-4 deg of outside temp,,,insulate the floor Only and have plenty of ventilation
