Every time I try to search this subject all I get is info on garage or lanai insulation!!

Be careful especially if you have an asphalt shingle roof. Sun heats up the roof and foam insulation will create a lot more heat between the roof and the foam insulation and could cause damage to your roof. Also if you have a small roof leak you will never know it since the water can not go through the foam. Check with a roofer. Friend in S. Florida had it and it worked great but problems I cited MIGHT occur later
