Spray Polyurethane Foam

Spray Polyurethane Foam (SPF) Roofing is a seamless, monolithic closed cell roofing system that is suitable for a wide range of new construction as well as retrofit roofing applications. SPF Roofing systems are unlike any other type of roof system in that they are “manufactured” in the field. Specialized plural component spray apparatus are utilized for the application of the materials directly to the roof deck or existing substrate. The SPF is applied in a continuous, seamless self-flashing operation. The SPF can be tapered in the field to direct water to existing drains or scuppers to eliminate ponding water problems that plague most other roofing systems. SPF is fully adhered with no gaps or seams which prevents any lateral movement of water in the roofing system in the event of damage, thus making leaks easy to identify and repair unlike any other roof system. After application of the SPF, a protective coating is also spray applied in one continuous seamless application in multiple coats. Depending on the type of coating being applied, roofing granules can be applied directly into the topcoat of the roof system.
Owners and facility managers looking for a roof system with the highest return on investment, increased energy savings and an indefinitely renewable roof system (through periodic re-coats) should look no further than a Cardinal Commercial Roofing and Insulation SPF Roofing system.


Spray Polyurethane Foam Layering

  • SPF is a closed-cell insulating product preventing any lateral or vertical transmission of water.
  • SPF is monolithic; no laps, seams or joints.
  • SPF is self-flashing.SPF is impervious to ultraviolet rays.
  • The SPF insulating factor is significant, an “R”- value of 6.8 per inch, thereby saving heating and cooling costs. SPF acts as an exterior thermal blanket, which shields the existing surface from solar heat and winter cold, thus reducing thermal shock and its resulting damage.
  • Compressive strength of SPF Roofing Foam is 40-50 P.S.I.
