St. Louis can be brutal when it comes to weather extremes. Ice storms and temperatures in the teens can storm through our city in January and February. Cardinals baseball means triple-digit scorchers in the bleachers during August. Business owners looking for a reliable roofing solution may wonder, “How does spray foam respond to such temperature extremes?”

At first glance, the word ‘foam’ might make you think that SPF is a pushover. Don’t worry- spray foam is no lightweight. R&A Contracting installs FOAM-LOK 2000 closed-cell spray foam from Lapolla Industries that has a 40-48 psi tensile strength. Click here to read more specifications about FOAM-LOK 2000. Spray foam is applied in liquid form and immediately starts its expansion and bonding process. The dual compound of polyol fiber and isocyanate mean that the spray foam reaches 90 percent strength in less than half an hour. The two compounds adhere to any surface it comes into contact with and strengthens upon expansion.

The closed-cell composite means that microscopic pockets of gas, not air, are trapped inside the foam’s interior. If you remember science class, gas is heavier than air. That means a strong, more durable vapor (gas) is structured inside the foam. When outside pressure, like foot traffic, or temperature fluctuations impact the foam, the gas gives a natural strength reinforcement to withstand the pressure.

So, what does this mean for SPF’s survival in extreme temperatures? The closed-cell construct means that outside air and the sun’s harmful UV rays are not penetrating the foam’s density. An elastomeric or acrylic coating gives another layer of protection against the elements, like sunscreen protects our skin from overexposure.

Our R&A Contracting teams have installed spray foam on commercial buildings across St. Louis and eastern Missouri. We are consistently impressed with how well spray foam lives up to its 6.3 R-Value rating as the most energy-efficient commercial roofing solution available today. You will not find a better roofing solution to cover your business, period. Rain, snow, ice, or sun, spray foam can keep you covered in any season for years to come.

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.”

“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.”
