I was checking into a poly foam roof for my camper, but the info online makes me wonder how it would work on my house. Anyone have experience with this type of roofing system? Will it work in higher pitch roofs? What about handling sustained winds? Katrina loved my shingles.
Retired now, was a Fl. roofing Contr. The foam has been around for 20+ years. Great isulation, but only as good as the protective coating, most do not last many years. The foam is very brital, movement on camper would be a problem. Is not wrinkle free, so appearance would be a drawback. Would suggest a top of the line elastomeric coating. Buy the best you can find, Need one w/ high content of polymer, and little fillers. BH
We are currently using the Demilec Sealection 500 on the underside of the roof sheathing. It has spectacular performance! We completed an air test prior to crawl sealing on an energy star home yesterday with 50 pascals negative pressure and were lees than 2 air changes an hour. The air seal and slow heat saturation make the product out perform all other insulations. Browse the web for the "R value Myth."
In our knowledge base Demilec is the only company which provides all the necessary documentation which meets all the code criteria.
On wood framing you can only use the open cell foam which is vapor permeable. Many of the older foams which were sprayed over wood caused significant problems because they were closed cell. The closed cell foam is a vapor barrier which will cause wood to rot. It is a spectaculr product when applied to steel or masonry.
I've haed a foam roof on my house for about 18 yrs now --flat roof with gravel on top of foam edges protected with cover of special coating. worked great for 8 yrs --tree fell through roof and have had hard time stopping leaks where two foams came together --solved problem with roof repair liquid. In general well pleased

I'm doing a report in my materials class about Enovate closed cell spf. Anyone worked with it before? If so, what are the advantages/disadvantages to regular closed cell, open cell, and fiberglass insulation. Any info specific to florida is also great. You can email me at manbeastmatt@yahoo.com. thanks a million.
I have used Icyene as well as a Soy-oil based spray foam. Both create a super tight building envelop, problem is it is not a DIY product, if that is what you are looking for.
I am building a house with a 45 foot high wall on a hill side. I have Pro intaller using pump jacks with have a smaller footprint than traditional scaffording. They do require a way to attach to the house. We are making permanet anchors points so that future exterior work will be a "breeze".
