R&A Contracting - Spray Foam St. Louis

Building owners across the U.S. are raving about spray foam for their roofs. You may wonder, “It’s spray foam- how fantastic could it possibly be?!” Prepare to be wowed!

Spray foam is delivered in liquid format contained in large drums that are transported to the jobsite. The drums contain two separate chemical elements: isocyanate, a type of polyurethane, and polyol fiber, a hard resin-type material. A spray applicator (hence the name ‘spray’ foam) is used to extract the liquid from the two drums and then applied (hence the name ‘applicator’) on the roofing surface. And that’s when spray foam starts its magic.

You may be tempted to think, “If the spray foam is liquid, won’t it just slide off any slope before it has time to bond?” That’s a great question! The polyol fiber creates an adhesive bond to any roofing surface, even rock, metal, and brick. As soon as the two materials are mixed and sprayed, the spray foam instantly begins its expansion process. The chemicals react to each other and rapidly expand to as much as thirty times its liquid density.

So, what if you applied spray foam into tight spaces- how strong is the spray foam expansion process? Strong enough to raise sinking concrete slabs, such as porches, driveways, sidewalks and roadways! Construction crews are using spray foam to level depressed sections of concrete so they don’t have to rip out the old section, dispose of the debris, and pour new concrete. The time and money saved from using spray foam to level concrete sections is unbelievable.

Construction crews are also using spray foam in the form of Ditch Foam, or Saddle Foam as it’s often called, to support water and gas pipelines underground. The spray foam doesn’t settle over time like sand and rock does. It also never deteriorates. This eliminates any need for a crew to send personnel into tight spaces to secure supports and risk possible injury or even death. Using spray foam to safely and securely position water and gas pipelines also save time and money.

I’d be an idiot if I did not take this opportunity to communicate to you how much we appreciate the way in which you conduct business and take care of our facility. 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.”
