When people think of spray polyurethane foam (SPF), envelope insulation often comes to mind first, as awareness of the energy efficiency benefits of the material have surged in recent years and accelerated insulation applications in tandem. However, spray foam was first proven as a viable, high performance material for roofing retrofits and this is where the product initially built its reputation for durability and energy performance.

But 2018 just may prove the pivotal tipping point for spray foam roofing sales, for a few key reasons.
