Did you know that the R-Value of a commercial roofing solution is dependent on how correctly it’s applied?

Commercial roofing insulation is designed to be installed in contact with air barriers on all six sides. If there are gaps or voids in the insulation, the R-Value is functioning at only a fraction of its R-Value rating. Spray Polyurethane Foam changes the R-Value function, which makes all the difference. (Not sure what R-Value is? Here’s a http://rnacontracting.com/real-dating-sites/.)

Closed-cell Spray Polyurethane Foam acts as both insulation and air barrier by nature of its chemical compound. When SPF is sprayed into place, the foam immediately begins its expansion process. The closed-cell spray foam seals off air transfer and eliminates any need for additional air barriers.

Spray foam can help reduce the convection heat transfer load of any commercial building, a benefit that isn’t calculated into R-Value ratings. Building attics can often exceed 120°F during the summer months, which places a significant heat load on HVAC. Spray Polyurethane Foam’s insulating element and air barrier function reduces heat transfer, effectively lowering your attic’s vented temperature to around 80-90°F, even on the hottest summer day.

If you want to know the difference between other commercial roofing solutions and SPF, visit an attic with an SPF-covered interior radiant surface. You will be amazed at the difference. The conduction properties of SPF are well-documented in its industry-leading R-Value and K-Factor ratings. What isn’t so easily captured is the secret sauce of SPF: the air barrier and insulation working as one to reduce convection impact and radiant temperature.

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.”

Will from O'Fallon, MO
