What are the advantages to a Spray Polyurethane Foam Roof?

The benefits of installing a spray polyurethane foam (SPF) roofing system, rather than another roof type, are numerous regarding installation, performance, cost, and longevity.

  • Energy Efficient – SPF delivers thermal, air, and moisture barriers to provide the highest R-value per inch, which means the material provides better insulation for the building.
  • Durability – The foam material can expand and contract with the building in accordance with outside temperatures, decreasing the likelihood of cracks and splitting.
  • Seamless and Waterproof – Since the SPF mixture is applied as a liquid, it can fill gaps, seams, and cracks in the existing roof and substrate.
  • Environmentally Friendly – Unlike other roofing systems, installing an SPF roof does not produce waste, and when properly maintained, SPF roofing systems stay out of landfills.

What are the disadvantages to a Spray Polyurethane Foam Roof?

While the advantages of an SPF roofing system outweigh the disadvantages, there are a few things you should keep in mind.

  • Hire the Right Professional – The application of the spray is a process that needs to be done correctly from the beginning.
  • Timing is Everything – Installation of an SPF roofing system cannot be performed during cold, windy, or rainy weather. In addition, the existing roof needs to be completely dry and pass an infrared moisture survey.
  • Prone to Mechanical Damage – SPF does not have as high of resistance to punctures, from mechanical damage and in some regions, can be prone to birds pecking, as other roof systems; the repair process is straightforward with a standard cartridge of caulk, unlike other system repairs.
  • Overspray - Spray foam is sort of like a mist. It's lightweight. It can be carried by the wind onto undesirable assets, such as cars. Contractors combat this by using windscreens, spraying out of a booth, or not spraying when it's too windy.
