Diy Foam Roofing. Foam roofs are commonly used in many commercial industrial and institutional flat roof settings. I thought that eichler owners who have spf roofs sprayed polyurethane foam might be interested in hearing how a do it yourselfer re coated their own roof for about 650 in supplies as opposed to paying a roofing company 6 000 to do it. If you recoat your roof over exposed foam you risk trapping moisture into the foam which will cause gases to form and blisters will start to form and erupt ruining the whole roofing system.
My spf roof was installed in 2001 by a company that is no longer in business. Primarily a foam roofing system provides a good amount of insulation.

Closed cell interior spray foam. And how much damage a rise in temperatures could cause is debatable. Foam roofing is usually applied to the roof as a spray. Primarily a foam roofing system provides a good amount of insulation.
