Sprayed Polyurethane Foam is applied as a liquid using plural-component spray equipment to fill cracks and crevices. It then expands to approximately 30 times its original liquid volume to form a extremely dense, closed-cell monolithic seamlessly sealed roof surface.  The Polyurethane Foam dries within seconds after being applied to the roof surface. Its expansion results in a weather tight roofing membrane that is fully adhered to the substrate. Because of polyurethane's light weight, it adds little additional weight to the system and is ideally suited to re-roofing applications. Polyurethane foam has a history of more than 40 years as a sustainable roofing medium. Polyurethane foam adds excellent above deck insulation value to the structure and utility bills can significantly reflect the difference.

SPF Roofing Systems provide many benefits to building owners; the two most prominent being

waterproofing/leak prevention and high insulation value.  Many additional benefits also exist such

as superior compressive strength, light weight, self flashing, condensation control, durable and sustainable for

the life of the structure. 

industrial spray polyurethane foam roofing



  • Leak free monolithic seal is completely waterproof

  • Self flashing, lightweight & highly durable

  • Highest insulation value provides energy savings

  • Withstands extreme weather, such as hail - insurance companies prefer SPF roofing in hail prone areas

  • Strong adhesion & wind uplift resistance - rated hurricane proof
  • Requires NO fasteners, which eliminates leaks and thermal bridging
  • UL & FM approved systems
  • Versatile, build in slope to drain on flat roofs
  • Ease of maintenance (Texas A&M reduced their maintenance crew from 32 to 3 after installing over 8 millions sf of SPF roofs
