Understanding the Spray Polyurethane Foam (SPF) Application Process

Myths about SPF insulation - R&A Contracting

When it comes to protecting your roof, Spray Polyurethane Foam (SPF) is the best choice available. One of the great attributes to an SPF cool roof is its ability to withstand even the most severe weather elements. With routine re-coatings, an SPF roof has a lifetime guarantee. So, how is a SPF roof installed?

Spray Polyurethane Foam is first applied in liquid format that can adhere to any roofing substrate. The liquid form of SPF is a combination of a polyol blend and isocyanate that rapidly bonds together upon contact. During application the SPF expands to almost twenty times its liquid density, creating a monolithic covering over any roofing surface.

The energy efficiency of SPF is a massive cost reducer for any commercial building. A standard SPF cool roofing solution can reduce HVAC costs by up to 30% per year! The airtight density of SPF creates a highly insulated covering that registers upwards of 6 R-Value in heat resistant indexes. Continued protection against ultraviolet (UV) radiation is made possible through a thin elastomeric coating that can be continuously reapplied to protect the base coat of SPF. Re-applications are recommended once every 10-15 years, which is a significant change from continual maintenance of other commercial cool roofing solutions.

In my experience you, and your team, are at the top of the list of all the roofing companies I’ve dealt with over the years. Thank you!

Eric and crew were really nice to have around. They were courteous, careful and caused little if any disruption. Their work looks good too! To be honest… a good experience with a product that I initially had misgivings about. I’m a convert because of Bubba, Sam and Eric. Thank you.

“I want to thank the crew at R&A for a job well done on our very leaky roof at the shop. It is certainly nice to have the drips and rivers gone from the shop when it is raining. I also wanted you to know how much we appreciated that the guys were able to stay out of our way and allowed us to do business as usual without any problems or interruptions. The roof looks great and the clean-up after the job made it so we couldn’t even tell you’d been here. Thanks for doing what you do so well!”

Jay Moore, President of Safe Way Tire and Auto Center

“My wife and I were on vacation when water pipes burst in our house. We got a hold of Craig and the R&A crew was able to start evacuating the water immediately. The best part was that they were able to start work before we even returned home. It was a very fast turnaround considering the extensive amount of water damage.”

Will from Dardenne Prairie, MO

“Craig and Mike came out in a timely fashion when we needed the work done. They did a reliable and quality job.”

Jerry from SLR Properties

“Craig helped us out tremendously with the insurance process. Timely and very professional.”

Lindell from Greater Missouri Builders (GMB)

“We purchased a house and there was some damage to the roof. Very impressed with the thoroughness of Mike’s inspection. Very comfortable with their explanation of what needed to be fixed. Most impressive was the way they protected our landscaping. Really liked the way they treated me as a valued customer, even though it was only a small project.”

Ross from Troy, MO

“I use R&A Contracting when my commercial roofs receive storm damage. They work on our behalf through every step of the insurance claim process. They perform all of the work and complete the insurance process, making our roofs better than they were before the storm.”

Director of Facilities for a large Property Management Company

“The team at R & A Contracting responded immediately when notified of our water disaster. They removed water-damaged materials and property quickly and restored our home even before the final settlement from our insurance company. They minimized how long our family had to live in a hotel and got us back to normal as fast as possible.”
