my dad has been spraying foam on roofs now for almost 30 years. we have been in business for our selves for about 3. to apply one inch of foam with 30 mills of coating and granuels to protect the foam it runs from $1.55 to $2.00 per square foot. the r value in an r7 per inch applied. we have applied up to 10 inches for those that wish for that kind of insulation. we are out of apache junction az. If u have any questions just call gary at 480 316 2504hmmm i have thought of that process before, what type of equip do you need and what kinda cost factors are involved? what kinda R value does it give per sq inch? or where can i find out more info on it
I seen many spray foam roofs. Once you get it down and have the tools in is very simple to do. However when they leak.... wow! do they leak they are like a sponge. You can step on a blister and squirt water up to your eyes. That is no jokeI've considered spray foam for roofing, however I'm no scientist and the setup costs are incredible.
