Houston County, GA | My dad is highly against spray foam unless you are making a refrigerator room. Eventually two chemicals break down. If you have a roof leak where will the water go? Pinnacle shingles say they void the warranty on your shingles due to the heat spray foam generates. Sun beats down and heat can't go anywhere under the felt and plywood. You have to have a air inductor to bring fresh air in, old air out. He did a house it was $5000 to do regular isolation and $18000 for spray foam with the air exchange. | |
